Abstract: It is an object of the present invention to provide a technique for making a semiconductor device thinner without using a back-grinding method for a silicon wafer. According to the present invention, an integrated circuit film is mounted, thereby making a semiconductor device mounting the integrated circuit film thinner. The term “an integrated circuit film” means a film-like integrated circuit which is manufactured based on an integrated circuit manufactured by a semiconductor film formed over a substrate such as a glass substrate or a quartz substrate. In the present invention, the integrated circuit film is manufactured by a technique for transferring.

Abstract: A gate metal is formed in a film, the foregoing gate metal is partially etched per each TFT having a different property, and a gate electrode is fabricated. Specifically, a resist mask is fabricated by exposing a resist to light per each TFT having a different property which is required. A gate metal is etched per each TFT having a different property which is required using the foregoing resist mask. At this time, a gate metal covering a semiconductor active layer of a TFT except for the TFT during the time when the patterning of a gate electrode is performed is left as it is covered. The step of fabricating a gate electrode of each TFT may be performed under the conditions optimized in conformity with the required property.
