Patent ID: 8207024

Claim:
A method of manufacturing a semiconductor device comprising: forming an amorphous semiconductor film over an insulating surface; irradiating the amorphous semiconductor film with a laser beam while scanning the laser beam in a first direction so that crystals are grown along the first direction; patterning the crystallized semiconductor film to form a crystallized semiconductor island; forming a first thin film transistor comprising a first channel region in a first region of the crystallized semiconductor island so that a channel length direction of the first channel region is the first direction; forming a second thin film transistor comprising a second channel region in a second region of the crystallized semiconductor island so that a channel length direction of the second channel region is different from the first direction; forming a capacitor comprising a third region of the crystallized semiconductor island; and forming a light emitting element electrically connected to the first thin film transistor and the second thin film transistor, wherein the first thin film transistor, the second thin film transistor and the light emitting element are formed in a pixel, and wherein the first region, the second region and the third region are adjacent to each other.
