Title:
PRECISION TOOL TIP CONTACT MODULE AND CONTACT METHOD USING SAME
Document Type and Number:
WIPO Patent Application WO/2017/116178
Kind Code:
A1
Abstract:
The present invention relates to a contact module for causing a precision tool tip for micro-processing to contact an object to be processed. Disclosed is a contact module comprising: a stage unit comprising a first stage, on which the object to be processed is seated, and a second stage arranged to face the first stage such that the precision tool tip, which protrudes toward the first stage, is provided thereon; a coating unit comprising a first conductive layer applied on the precision tool tip; a contact unit comprising a first contact portion and a second contact portion, the first contact portion being at least partially made of a conductive material and arranged on the second stage so as to protrude toward the first stage and to be spaced from the precision tool tip, and the second contact portion being at least partially made of a conductive material and formed on the first stage so as to protrude toward the second stage and to be spaced from the object to be processed; a sensing unit comprising a first conductive line connected to the first conductive layer and to the first contact portion such that an electric signal can flow therethrough and a second conductive line connected to the second contact portion such that an electric signal can flow therethrough, the sensing unit transferring an electric signal to one of the same and sensing whether the same contact each other or not on the basis of a sensed change; and a control unit for causing the first contact portion and the precision tool tip to continuously contact the second contact portion such that the relative position between the first contact portion and the precision tool tip is derived therethrough, the control unit causing the first contact portion to contact the object to be processed and then moving the precision tool tip as much as the relative position such that the same makes a contact.
