Title: Device and method for laser beam irradiation and method of designing the device
Inventor: TAKANO YOSHIE
IPC: G02B26/10
Filed: 2002-09-20
Abstract: <P>PROBLEM TO BE SOLVED: To solve the problem that, when vertical aberration (light rays passed through a lens etc., are not concentrated properly to one point and form an imperfect image) caused in an object to be irradiated by means of the optical system of a laser beam irradiation device is unignored, uniform laser beam irradiation is difficult due to uneven laser beam irradiation intensities produced in the surface of the object and, in addition, since the aberration becomes different depending on the arrangemenet of lenses etc., and characteristics of the lenses, the aberration must be taken into consideration at every optical system.  <P>SOLUTION: The aberration of an optical system is corrected on a substrate 104 side by causing a setting-up base on which the object to be irradiated is set up to suck the substrate 104 by deforming the base in accordance with the aberration of the optical system. It is also possible to correct the aberration of the optical system by performing laser beam irradiation while the substrate 104 is moved vertically in accordance with found aberration. When the aberration of the optical system is corrected on the substrate 104 side, the uneven laser beam irradiation intensities can be reduced. When a TFT is formed in this way, the variation of electrical characteristics of the TFT can be reduced, because uneven laser beam irradiation is eliminated.  <P>COPYRIGHT: (C)2004,JPO
