Abstract:
A method for manufacturing a semiconductor device comprising the steps of:forming a semiconductor film over a substrate; first irradiating a first pulsed linear laser light to said semiconductor film, while moving said substrate in a direction perpendicular to a longitudinal direction of said first pulsed linear laser light; second irradiating a second pulsed linear laser light to said semiconductor film, while moving said substrate in the direction perpendicular to the longitudinal direction of said second pulsed linear laser light; and forming a plurality of thin film transistors having active regions using said semiconductor film, each of said active regions including source and drain regions and a channel region interposed therebetween, wherein the first and second irradiating steps are conducted in such a manner that an irradiation area of one pulse is partly overlapped with a next pulse, and wherein each of said active regions is formed in such a manner that a line connecting said source and drain regions is parallel to the longitudinal directions of said first and second pulsed linear laser lights.
