Title: Exposure method of photoresist layer for formation of fine pattern
Inventor: KIM CHOE DONG
IPC: H01L21/027
Filed: 1998-12-24
Abstract: PURPOSE: A method for exposing a photoresist layer is provided to obtain more exactly a fine pattern. CONSTITUTION: In a photomasking process for defining a pattern line(11) on a substrate(10), a light emitted from a light source(S) is reflected by a spherical mirror(M) and then travels in parallel. At this time, the light oscillates in every direction. When the parallel light is projected to a reflect material at a specific incidence angle(theta), the light reflected by the reflect material has a certain oscillating direction(DR1). Therefore, the position of the reflect material is adjusted so that the reflected light may accord with a direction of the pattern(11). Thereby, a resolving power of an i-line stepper with wavelength of 365 nm is improved and a margin of the photomasking process is increased. On the other hand, a light polarized to one direction passes through a double refraction material having different refractive indexes according to each axis, and then projected to the pattern.
