Title: Pattern forming method for semiconductor device
Inventor: TSUTSUI HIROAKI
IPC: G03F7/20
Filed: 1987-05-06
Abstract: PURPOSE:To obtain the relative arrangement of patterns with excellent accuracy, by performing a developing process after a first exposure, and performing a second and the following exposures applying the position alignment mark contained in a pattern actually shown in a photoresist as a reference. CONSTITUTION:When a pattern A is exposed in order and subjected to a first development, the pattern A of a resist is formed in a region of the pattern A. In the case where positive resist of novolac system and the like is used, the resist is left as it is on the region of a pattern B because it is not exposed. When the pattern B is exposed in order by using a position alignment mark C in the pattern A, and a second development is performed, the pattern B wherein the relative position alignment to the pattern A is exactly finished can be obtained. Thereby, the relative arrangement of patterns formed by a plurality of exposure regions can be obtained with high accuracy.

Abstract: PURPOSE:To reduce the size of the electrostatic charging device, and to reduce the fitting space and also to decrease the current capacity of a high voltage power source by using an insulating material for the shield member of a corona wire. CONSTITUTION:An insulating shield 2 is used as the shield member of the corona wire 3. The shield 2 is formed by etching a glass bar of, for example, 5mm. square with hydrofluoric acid and thus working it in a recessed shape; a dimension A is 2mm. and dimensions C and D are 5mm.. Consequently, no coroma current flows through the shield 2 and discharge becomes hard to occur; and the distance between the wire 3 and a photosensitive drum 1 is shortened, so the sectional area CXD of the electrostatic charging device is reduced to one fifth as large as before and the fitting space is put closer to the drum 1 and, therefore, one tenth as large as before. Further, a discharging current flows to only the photosensitive body side, so the current capacity of the high voltage power source is reduced.
