Abstract

PURPOSE:To prevent damage to a substrate by additionally covering the parts except the target forming region with a separate photo resist film wherein the above process is done when etching formation is made to the target pattern on a semiconductor substrate by consisting a photo resist as a mask. CONSTITUTION:When the target is made by utilizing photo etching process for isolation diffusion, an oxide film 8 is formed on the silicon substrate 7 and the oxide film 8 is furthermore covered with the first photo resist film 9. Next, a desired pattern is formed by partially exposing the photo resist film 9 and a window 10 for isolation and windows 11 for target are formed by consisting the photo resist film 9 as a mask and by etching the oxide film 8. After that, the surface of the first photo resist film 9 except the region which becomes a target is covered with the second photo resist film 12 and a target pattern 13 is formed on the silicon substrate 7 by etching treatment. In this way, damage to the isolation region 10 will be prevented.
