Title: Formation method of resist pattern
Inventor: AKAMI YUTAKA
IPC: H01L21/027
Filed: 1991-10-08
Abstract: PURPOSE:To obtain the formation method, of a resist pattern, wherein the time of a reduction-exposure operation is short and the resist pattern of high resolution can be obtained. CONSTITUTION:A g-line resist layer 10 which has been formed on a substrate 4 is coated with an i-line resist layer 15 so as to be thinner than the g-line resist layer 10. When a prescribed pattern is reduction-exposed on the i-line resist layer 15 via a lens 2, the i-line resist layer 15 is bleached to the prescribed pattern. After the whole face has been exposed to a g-line by making use of the i-line resist layer 15 as a mask, it is developed. Thereby, the g-line resist layer 10 is patterned. Consequently, since the prescribed pattern is reduction- exposed on the thin i-line resist layer 15, the time of a reduction-exposure operation is reduced and the throughput of the exposure operation is enhanced. Since the resist pattern of the i-line resist layer 15 which has been brought into close contact is used as the mask, it is possible to obtain the resist pattern of high resolution.
