[0045] Integrated metrology system with multiple support units

[0046] There is provided an integrated metrology system that is both stable and compact.

[0047] It has been found that during the transportation of the integrated metrology system, the integrated metrology system should have a large support base which will contribute to the stability of the integrated metrology system during the transportation of the integrated metrology system. [0048] After the integrated metrology system is transported to its desired location - the large support base may not be required - especially as the large support base unnecessarily increases the footprint of the integrated metrology system.

[0049] There is provided an integrated metrology system that has (a) a main body 110 that has a rear side and a front side, the rear side faces the other system; the front side defines a front border 140 of the main body; (b) one or more detachable supporting units 130 that are detachably coupled to the main body and support the main body while extending outside the front border; and (c) at least one auxiliary supporting unit 150 that is configured to support the main body at an absence of the one or more detachable supporting units.

[0050] After the integrated metrology system 100 is installed (see for example figure 9) - the one or more detachable supporting units 130 may be removed and the main body 110 may be supported by the at least one auxiliary supporting unit 150. The at least one auxiliary supporting unit 150 does not extend outside the front border as much as the one or more detachable supporting units do - and may even not extend outside the front border at all.

[0051] The support base may be defined by (a) at least one additional supporting unit 160 positioned below the main body and either one of (b) one or more detachable supporting units 130 (when still connected to the main base), and (c) at least one auxiliary supporting unit 150 (when positioned to support the main body.

[0052] The distances between the at least one additional supporting unit 160 and the one or more detachable supporting units 130 exceeds the distances between the at least one additional supporting unit 160 and the at least one auxiliary supporting unit 150.

[0053] Each supporting unit out of the at least one additional supporting unit, one or more detachable supporting units and the at least one auxiliary supporting unit may be movable in relation to floor on which the integrated metrology system is positioned, or may be fixed.

[0054] The at least one auxiliary supporting unit 150 is configured to move in relation to the main body along a first direction (for example upwards and downwards) - between a position (upper position) in which the at least one auxiliary supporting unit contacts the floor and another position (lower position) in which the at least one auxiliary supporting unit does not contact the floor.

[0055] The one or more detachable supporting units 130 are configured to move in relation to the main body along a second direction (for example outside the main body - in a horizontal direction). [0056] The first direction may differ from the second direction.

[0057] The one or more detachable supporting units 130 may be removed after the at least one auxiliary supporting unit 160 is moved to the lower position - in which they support the main body.

[0058] Examples of the various supporting units are shown in figures 12-13. There may be any number of supporting unit of any type (detachable, auxiliary, and additional supporting units). [0059] Each detachable supporting unit 130 includes a wheel 132, and an arm 134. The wheel 132 is illustrated as having two degrees of freedom.

[0060] Wheel 132 may rotate about wheel’s axis 131. Wheel’s axis 131 connected to wheel’s housing 137 that in turn is rotatable along further axis 135 (in relation to the main body). In figures 12 and 13 the wheel’s axis is horizontal and the further axis is vertical.

[0061] The arm 134 may be supported by a support frame 119 that defines a support frame inner space 113 in which the arm 134 may move - for example perform a horizontal movement - towards the main body and outside the main body.

[0062] In figure 12 the arm 134 is outside the support frame inner space 113 and in figure 13 the arm is partially within the support frame inner space 113.

[0063] In order to move within the frame inner space, a rear portion of the arm 134 is shaped and sized to move within the support frame inner space 113.

[0064] The arm 134 may be fixed to the support frame 119 by a fixation element 117 that is configured to hold the arm at a fixed position while the arm is partially positioned within the frame inner space. The fixation element 117 may be a pin that may be pushed or rotated inside an aperture (maybe a threaded aperture) formed in the support frame - thereby pressing the arm towards another side of the support frame.

[0065] The arm 134 may include an arm’s cavity 133 in which an edge of the fixation element 117 may be positioned when fixing the position of the arm.

[0066] Each additional supporting unit 160 may be positioned below the main body and may include an additional wheel 163 and an additional housing 167. The additional wheel 163 may rotate about an additional axis 161 that is rotatably coupled to the additional housing 167.

[0067] The additional housing 167 may be fixed to the main body or may be rotatably coupled to the main body by yet another axis (not shown) - thereby allowing the additional wheel to have two degrees of freedom. [0068] Each additional supporting unit 160 may be closer to the rear side of the main body than the detachable supporting unit 130. Any other position of any of the support units may be provided.

[0069] The auxiliary supporting unit 150 may be a leg, may include wheel, may be fixed to the main body or may move in relation to the main body. The movement (between an upper position to a lower position) may be done by rotation, in a linear or non-linear manner.

[0070] Movable keyboard

[0071] A safety border (also referred to as “Safety light barrier” and also referred to as “Light Curtain”) (denoted 142 in figure 7) may be defined by a user of the integrated metrology system 100. A user may not operate the integrated metrology system 100 (and/or even the other system 10) when any part of the integrated metrology system 100 crosses the safety border 142. There may be provided one or more sensors that monitor the safety border and check whether the keyboard or any other component passed the safety border - and when a crossing occurred - generate an alert, prevent the progress of a manufacturing process, and the like. In figure 7 the safety border 142 is defined by a part 143 of a frame of the other device.

[0072] The integrated metrology system 100 includes a keyboard that when used extends outside the main body.

[0073] Maintaining the keyboard open may either cross the safety border or may force the main body of the integrated metrology system 100 to be small enough to enable the integrated metrology system 100 not to cross the safety border even when the keyboard is open.

[0074] There may be provided an integrated metrology system that may include (a) a main body 110 that has a rear side and a front side, the rear side faces another system; the front side defines a front border 140 of the main body, (b) a front interface 210, and (c) a keyboard 200 that is movably coupled, via the front interface 210, to the main body.

[0075] The keyboard 200 is configured to be moved between multiple positions, the multiple positions includes a first position and a second position.

[0076] When positioned at the first position (Extended position or Open position) the keyboard extends outside the front border 140 by a first distance. The first distance may be about the width of the keyboard.

[0077] When positioned at the second position (Folded position or Closed position), the keyboard does not extend outside an imaginary line that is located up to a second distance from the front border, the second distance is smaller than the first distance. The imaginary line may fall on the front border 140 - or may be spaced apart from the front border 140.

[0078] In figures 1-5 the keyboard is in the first position.

[0079] In figures 7-11 the keyboard is at the second position.

[0080] Figures 22 and 23 illustrate scenarios in which the keyboard is in the first position and additional scenarios in which the keyboard in in the second position.

[0081] Figures 22 and 23 illustrate a second position in which the keyboard still slightly extends out of the first border and also illustrated a recess 209 formed in the main body in which the keyboard and the front interface may fully or partially enter) when positioned in the second position.

[0082] The keyboard (or rather the front interface) may be rotatably coupled to the main body - for example by keyboard axis 207.

[0083] The keyboard axis may be located near a top of the keyboard. Figure 22 illustrates keyboard axis 207 located near a bottom the keyboard.

[0084] The second position may be a vertical position or almost vertical position (see figure 22) and the first position may be a horizontal position.

[0085] The keyboard may be non-rotatably coupled to the main body.

[0086] There may be provided a keyboard fixation element for holding (by mechanical means and/or electromagnetic means) the keyboard in the second position.

[0087] The keyboard may be replaced by another unit that is movable between different positions- including an open position and closed position.

[0088] Heat evacuation and maintainable integrated metrology system [0089] The integrated metrology system 100 is connected (via a rear interface) to another system. It may be desired to perform maintenance operations without disconnecting the integrated metrology system 100 from the other system.

[0090] The integrated metrology system 100 may include a main body frame and multiple panels that protect the main body. The panels are detachably coupled (for example via clips, screws, bolts and nuts) to the main body frame- so that they can be easily removed during maintenance operations. The main body frame may include openings (such as opening 109 of figure 16) that ease the access to various parts of the main body.

[0091] Furthermore - in order to ease the maintenance and/ or to ease upgrades of the integrated metrology system 100 - the integrated metrology system 100 may have a modular configuration. Various components of the integrated metrology system 100 may be arranged as detachable modules that are located in multiple compartments of the integrated metrology system 100.

[0092] The integrated metrology system 100 may include a very powerful light source that may dissipate a substantial amount of heat.

[0093] In order to prevent the heat from distorting optical components of the optical hard and from damaging or distorting other units of the integrated metrology system 100 - the light source is spaced away from the optical head. In addition - the heat is conveyed outside the main body of the by one or more air suction element such as air vents.

[0094] There may be provided an integrated metrology system 100 for evaluating semiconductor wafers, the metrology system may include a main body 110 that may include optical head 230 and light source 220.

[0095] The light source 220 is positioned at a lower portion of the main body. The optical head 230 is positioned an upper portion of the main body.

[0096] The optical head 230 is optically coupled to the light source 220 via an optical path that includes an optical cable (denoted 208 in figure 14 ) and may include additional optical components. [0097] Figures 14-15 illustrate the main body 110 as including multiple compartments - such as first till fourth compartments 211-214. The first compartment 211 is the lowest compartment and the fourth compartment 214 is the highest compartment.

[0098] The optical head 230 is located within fourth compartment 214.

[0099] Mechanical stage 280 and chuck 281 are located within third compartment 213.

[00100] Computer module 270 is located within second compartment 212.

[00101] Light source 220 is located within first compartment 211.

[00102] As indicated above - the light source 220 and the optical head 230 are positioned at different compartments of the main body, wherein the optical head 230 is located above the light source 220. In the example set forth in figure 14 and 15- second compartment 212 and third compartment 213 are intermediate compartments that are positioned between the light source 220 and the optical head 230.

[00103] As illustrates in figures 14 and 15- and especially in figure 21 - the air from the vicinity of the light source is evacuated (for example sucked) by one or more air suction elements 250 that are positioned below the light source 220. A perforated plate 290 (including apertures 291) is positioned between the one or more air suction elements 250 and the light source 220 and allow the one or more air suction elements 250 to such air from the space above the one or more air suction elements 250 - through the openings formed in the perforated plate 290. Additional perforated plates are shown in figure 15. There may be multiple perforated plates at the bottom of one or more compartment. [00104] The air suction elements 250 are positioned at a bottom of the main body and may extend (in part) outside the main body - and in a space 102 located below a lowest compartment of the main body.

[00105] The air suction elements may even evacuate air from at least a majority of the main body

- for example via apertures formed in the compartments - may such air from second compartment 212 and from any other compartment that is not sealed .

[00106] Figure 14-15 also illustrate that the optical head 230 is positioned below (and even only below) a high power mechanical stage control unit 260 of the integrated metrology system.

[00107] The light source 220 may be a laser driven light source.

[00108] A power consumption of the light source may exceed 50 watt. For example- it may range between 70 and 140 watts.

[00109] Figures 17 and 18 illustrates a mechanical stage 280 that support a chuck 281 and move the chuck in various directions (for example- X, Y and Z). There are also provided first end effectors 301 and second end effectors 302. The first end effectors 301 are positioned above the second end effectors 302. The first and second end effectors may be moved in various manners - for example upwards and downwards - in order to allow the first end effectors 301 to receive (from other system 10) a first wafer - while the second end effectors may receive from the chuck support another wafer

- that can be taken by the other system.

[00157] Any arrangement of components to achieve the same functionality is effectively "associated" such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality may be seen as "associated with" each other such that the desired functionality is achieved, irrespective of architectures or intermedial components. Likewise, any two components so associated can also be viewed as being "operably connected," or "operably coupled," to each other to achieve the desired functionality.

[00158] Furthermore, those skilled in the art will recognize that boundaries between the above described operations merely illustrative. The multiple operations may be combined into a single operation; a single operation may be distributed in additional operations and operations may be executed at least partially overlapping in time. Moreover, alternative embodiments may include multiple instances of an operation, and the order of operations may be altered in various other embodiments.

[00159] Also for example, in one embodiment, the illustrated examples may be implemented as circuitry located on a single integrated circuit or within a same device. Alternatively, the examples may be implemented as any number of separate integrated circuits or separate devices interconnected with each other in a suitable manner.

[00160] Also for example, the examples, or portions thereof, may implemented as soft or code representations of physical circuitry or of logical representations convertible into physical circuitry, such as in a hardware description language of any appropriate type.

[00161] However, other modifications, variations and alternatives are also possible. The specifications and drawings are, accordingly, to be regarded in an illustrative rather than in a restrictive sense.

[00162] In the claims, any reference signs placed between parentheses shall not be construed as limiting the claim. The word ‘comprising’ does not exclude the presence of other elements or steps then those listed in a claim. Furthermore, the terms “a” or “an,” as used herein, are defined as one or more than one. Also, the use of introductory phrases such as “at least one” and “one or more” in the claims should not be construed to imply that the introduction of another claim element by the indefinite articles "a" or "an" limits any particular claim containing such introduced claim element to inventions containing only one such element, even when the same claim includes the introductory phrases "one or more" or "at least one" and indefinite articles such as "a" or "an." The same holds true for the use of definite articles. Unless stated otherwise, terms such as “first" and “second” are used to arbitrarily distinguish between the elements such terms describe. Thus, these terms are not necessarily intended to indicate temporal or other prioritization of such elements. The mere fact that certain measures are recited in mutually different claims does not indicate that a combination of these measures cannot be used to advantage. [00163] While certain features of the invention have been illustrated and described herein, many modifications, substitutions, changes, and equivalents will now occur to those of ordinary skill in the art. It is, therefore, to be understood that the appended claims are intended to cover all such modifications and changes as fall within the true spirit of the invention.

[00164] The terms "including", "comprising", "having", "consisting" and "consisting essentially of are used in an interchangeable manner. For example- any method may include at least the steps included in the figures and/or in the specification, only the steps included in the figures and/or the specification.
