Title: Projection-exposure equipment
Inventor: SATO KAZUO
IPC: G03F9/00
Filed: 1985-11-22
Abstract: PURPOSE:To make it possible to form a fine pattern on an uneven substrate for the whole part of an original drawing, by exposing in order the image of the original drawing set in an exposure-optical system composed of a light source, original drawing, lens and substrate, in the manner in which the focus is taken partially and sequentially. CONSTITUTION:A substrate 4 is mounted on the substrate-fixing stand 8 of an equipment, and the profile of unevennes of the substrate surface is measured. In the measurement, the profile of unevenness is stored in an electric circuit 7, by using the scanning based on the shift of the fixing stand 8 and the detected values of height by an optical detector 6. Then an exposure process is followed. In order to focus exactly the pattern on the substrate 4 when a dimension (b) deviates by DELTAb because of the unevenness of the substrate surface, the substrate is to be shifted in the inverse direction by DELTAb, or the distance between the original drawing and the lens is to be varied by DELTAa. Accordingly, the whole part of the original drawing can be projected on the substrate 4 without defocusing, in the manner in which a part of the original drawing is shielded from light according to the data of the unevenness stored in the electric circuit 7, and moved upward or downward synchronizing with the light-shielding.
