Title: Manufacture of thin film transistor
Inventor: OKI KENICHI
IPC: H01L29/786
Filed: 1985-04-09
Abstract: PURPOSE:To prevent an electrode film from lifting off to cause electrodes to shortcircuit or the reliability to decrease by employing two resist films to control the sectional shape of the resist at lifting-off step time. CONSTITUTION:After a thin insulator film 13 of a Cr gate electrode 12 and an a-Si thin semiconductor film 14 are continuously formed on an insulating substrate 11, a resist 15 of first layer is coated, prebaked, and entirely exposed with exposure amount of 60-80% of the normal value from the side of a substrate surface. Then, a resist 16 of the second layer is coated, prebaked, and with a gate electrode 10 as a mask self-aligning exposure is executed from the back surface of a substrate. When a development is then performed, the resist 16 is stopped in dissolving at the edge 227, while the resist 15 is dissolved to the inside of the mask pattern, and a sectional shape 17 becomes an overhung state. Then, while the resist remains, source and drain electrode films are formed.
