Title: Manufacture of thin film semiconductor device
Inventor: SHIMOGAICHI YASUSHI
IPC: H01L29/786
Filed: 1993-12-22
Abstract: PURPOSE:To improve a hydrogen treatment in efficiency by a method wherein a glass substrate is subjected to a hydrogen process before a polycrystalline silicon film is formed and subjected to a transistor process. CONSTITUTION:First of all, a glass substrate 1 is previously lessened in defect level through a hydrogen treatment. Then, a semiconductor thin film 2 of polycrystalline silicon is formed on the surface of the glass substrate 1. A TFT 3 is formed as integrated by the use of the semiconductor thin film 2 as an element region. The glass substrate 1 is hydrogenated through such a manner that a hydrogen-containing film 21 and a hydrogen-shutoff film 22 are successively deposited on the surface of the substrate 1, and then the substrate 1 is heated. It is preferable that the hydrogen-containing film 21 and the hydrogen-shutoff film 22 are removed from the substrate 1 after the glass substrate 1 is hydrogenated. By this setup, the glass substrate 1 can be lessened in defect level, so that it is lessened in probability that hydrogen atoms introduced into the semiconductor thin film 2 are absorbed in the glass substrate 1. Therefore, the semiconductor thin film 23 is improved in hydrogenation efficiency.
