Title:
CRYSTAL MANUFACTURING APPARATUS, SEMICONDUCTOR DEVICE MANUFACTURED USING SAME, AND METHOD FOR MANUFACTURING SEMICONDUCTOR DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2010/023937
Kind Code:
A1
Abstract:
Provided is a crystal manufacturing apparatus capable of manufacturing a crystal in a desired position on a substrate. One end of a spring (2) is fixed to a rack (1) and the other end thereof is coupled to a magnetic body (3). One end of the magnetic body (3) is coupled to the spring and the other end thereof is coupled to a piston (6). A coil (4) is wound around the magnetic body (3) and electrically connected between a power supply circuit (5) and a ground node (GND). The piston (6) comprises a straight member (61) inserted into a cylinder (7). The cylinder (7) has a hollow columnar shape and comprises a small hole (71) in the bottom surface (7B) thereof. The cylinder (7) holds a silicon melt (13). A substrate (11) is supported by an XY stage (12) so as to face the small hole (71) of the cylinder (7). The power supply circuit (5) feeds a pulsed current to the coil (4) to move the piston (6) in a vertical direction (DR1). As a result, a droplet (14) is ejected from the small hole (71) toward the substrate (11) at an initial speed of 1.02 m/s.
