Inventor: TAKITA MASATOSHI
IPC: G02F1/1333
Filed: 1992-01-24
Abstract: PURPOSE:To improve the performance of a transistor by specifying OH group content and metal impurity content. CONSTITUTION:A quartz glass substrate for p-SiTFT is regulated to 50 or lower ppm OH group content, free from chloride and 1ppm or less metal impurity content. The quarts glass is warped at >=1000 deg.C when the OH group content is over 50ppm and is not warped even at 1000 deg.C or a higher temp. when the OH group content is 50ppm or less and the degradation of patterning accuracy is prevented. When chlorine is present, the problem about the characteristic of the transistor arises and internal resistance ratio (current ratio) at the time of on-off TFT is decreased and if chlorine is not present, the demerit is vanished. And when metal impurity particularly alkali metal impurity is present, the film forming is ununiformed or the electrical adverse effect to TFT element arises and when the metal impurity content is 1ppm or lower, the demerit is vanished.
