Title: Apparatus and system for electron beam lithography
Inventor: NAKAYAMA YOSHINORI
IPC: H01J37/317
Filed: 1990-08-01
Abstract: PURPOSE:To make it possible to form a microscopic pattern with high precision by providing a forming aperture obtained by processing a desired lithographic pattern element by using a means of correcting a proximity effect produced between patterns. CONSTITUTION:A point 16 and a point 17 are parts wherein a proximity effect between lithographic patterns is estimated to be produced easily, and they are taken as representative points whereat the quantity of stored energy is calculated. At these representative points, the distribution of the quantity of the stored energy in a resist film is determined by simulation and the proximity effect between the patterns is estimated preliminarily. Then it is determined that an unexpected resist pattern is formed at the point 16 while the energy in such a quantity as to have an effect on the formation of a resist pattern is not stored at the point 17. By deleting a part of a figure to be drawn, the resist pattern can be formed, as desired, at a point (x) 18 being the representative point by the proximity effect between patterns and, besides, the resist pattern may not be formed at the representative point 16. According to this constitution, a desired pattern can be drawn at a high processing speed and with high precision.

Abstract: PURPOSE:To make a snap.fastener not easily detach from a base plate by retaining the snap.fastener which is integrally molded on an upper cover, to a flat seat hollow provided on the base plate. CONSTITUTION:The flat seat hollow 21 is provided on the base plate 2 to retain the snap.fastener which is integrally molded on the upper cover, to the flat seat hollow 21.
