Abstract:
1. A method for manufacturing a semiconductor device, comprising the steps of: forming an insulating layer over a substrate; forming a non-single-crystal semiconductor layer over the insulating layer; irradiating a single crystal semiconductor substrate with ions to form a damaged region in the single crystal semiconductor substrate; attaching the non-single-crystal semiconductor layer and the single crystal semiconductor substrate to each other; separating the single crystal semiconductor substrate at the damaged region to form a single crystal semiconductor layer over a first portion of the non-single-crystal semiconductor layer; and forming a first gate electrode over the non-single-crystal semiconductor layer in a pixel region and a second gate electrode over the single crystal semiconductor layer in a driver circuit region after the separation of the single crystal semiconductor substrate, wherein the first gate electrode and the second gate electrode are formed in the same process.
