Title: Semiconductor device
Inventor: MORITA NAOYUKI
IPC: G03F1/44
Filed: 1988-01-14
Abstract: PURPOSE:To make a high-accuracy size control available, by equipping dummy patterns made of the same material as that of a size-measuring pattern, around the size-measuring pattern. CONSTITUTION:Around a size-measuring pattern 1, dummy patterns 2 made of the same material as that of the size-measuring pattern 1 are equipped. By this, the density of an actual semiconductor device is made equal to the pattern density near the size-measuring pattern 1 and thereby, a size difference caused at dry etching of a resist pattern can be completely avoided. Since there is no difference in size between an actual semiconductor device and the size-measuring pattern 1, a high-accuracy size control is possible.
