Abstract

PURPOSE: To obtain a semiconductor integrated circuit device in which a fine pattern is formed simply, surely and at low costs by a method wherein a photoresist film is exposed again by using a photomask in which a light- shielding pattern larger than a desired pattern has been formed. CONSTITUTION: First, a light-shielding chromium pattern 2 in a pattern size (b) which is larger than a desired pattern (a) is formed on a glass substrate 1. By making use of the chromium pattern as a mask, a photoresist film is exposed. Thereby, an exposure profile 3 which is steep and has a high optical intensity contrast is obtained. Then, the photomask is moved by [(b)-(a)], and the photoresist film is exposed again. At this time, an exposure profile 4 which is steep and has a high optical intensity contrast is obtained in the same manner as a first operation. Thereby, the exposure profile 4 in which a fine line pattern in the size (a) is steep and has a high optical intensity contrast is obtained. Thereby, a fine pattern can be formed simply, surely and at low costs.
