Title: Process and system for crystallizing semiconductor film
Inventor: ISHIDA ARICHIKA
IPC: H01L21/20
Filed: 2003-02-03
Abstract: <P>PROBLEM TO BE SOLVED: To provide a process for crystallizing a semiconductor film, and to provide a crystallizing apparatus (laser annealer) reducible in size.  <P>SOLUTION: An amorphous silicon thin film 17 of a glass substrate 16 placed on a stage 24 is irradiated with a laser beam B from a laser oscillator 21. Irradiating point of the laser beam B on the amorphous silicon thin film 17 is moved linearly to the scribe line 19 of a device 18 on the glass substrate 16 by means of a scan mirror 23. The stage 24 is moved in the direction perpendicular to the moving direction of the laser beam B irradiating point. The amorphous silicon thin film 17 is crystallized by laser annealing to obtain a polysilicon thin film. Moving range of the laser beam B irradiating point becomes smaller. A condenser leans 22 having an extremely long focal point is thereby not required. Every time when the laser beam B irradiating point moves, the stage 24 is moved by the beam width of the laser beam B. Moving speed of the stage 24 can thereby be lowered.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
