Title: Exposing method of electronic beam
Inventor: MACHIDA YASUHIDE
IPC: H01L21/027
Filed: 1979-12-12
Abstract: PURPOSE:To obtain the highly precise drawing of a microscopic pattern by removing the proximity effect using a method wherein the portions of the exposed pattern, having a smaller measurement of the distance to the adjoining pattern than the prescribed measurement, are discriminated and a reduced amount of exposure is exposed on said portions. CONSTITUTION:The portion B1, where the distance l between patterns A and B arranged in close vicinity each other is smaller than the distance l0 to be effected by the proximity effect arising from the reflection and scattering of the electronic beam on the substrate surface, is discriminated. In the case of the patterns A and B1, they are exposed after the amount of exposure per unit area is corrected to a smaller value taking into consideration of the proximity effect. The portion B2 having no proximity effect is exposed with the prescribed amount of exposure. Hence, the narrowing of the pattern interval due to an overexposure caused by the proximity effect is prevented and a highly accurate drawing can be performed.
