Title: Method for forming resist pattern
Inventor: YANAGAWA SHUSAKU
IPC: H01L21/768
Filed: 2001-04-02
Abstract: PROBLEM TO BE SOLVED: To accurately form a resist pattern on a substrate, where the thickness difference of resist occurs. SOLUTION: A quantity S of absorbed light in the resist shows dependency having cyclicity to the real thickness of the resist. Besides, such resist thickness dependency is changed a little by the thickness of a silicon oxide film, and the curve of dependency (standing wave curve) is shifted in the direction of lateral axis. Therefore, the top or bottom point of the standing wave curve is shifted between thickness D1 and D2 having a thickness difference (d) by adjusting the thickness of the silicon oxide film or the range of the thickness D1 and D2 having the thickness difference (d) can be shifted to the top or bottom point of the standing wave curve by controlling the thickness of the resist and a difference ΔS in the quantity of absorbed light between the thickness D1 and D2 can be reduced so that the dispersion of line width caused by the resist thickness difference (d) can be suppressed.
