Title: Manufacture of semiconductor device
Inventor: EMA TAIJI
IPC: H01L21/8242
Filed: 1990-11-09
Abstract: PURPOSE:To improve resolution and form a pattern with high precision, by performing exposure by using an exposure mask exposing a region smaller than a semiconductor device forming region, in independent basic unit regions where the same pattern is regularly repeated. CONSTITUTION:In a basic unit region where the same pattern is regularly repeated when photo resist is exposed, photo resist is exposed in each specified region of the basic unit, by using an exposure mask 10 exposing a region smaller than a semiconductor device forming region 2. When the other pattern is formed, exposure is performed for each unit of the semiconductor forming region 2. That is, as to an element wherein the pattern rule is strict, e.g. a contact hole, photo resist is exposed in a region smaller than the semiconductor device forming region 2. Thereby the resolution in the case of exposure is improved, and a pattern can be formed with high precision.

However, these methods are same in meaning such that both of them are mutually separated or at least one of them is temporarily preserved at crystallizing temp. Quenching and gradual cooling are relative to one compsn. and the boundary thereof is changed by a combination of a color former and a coupler. Then, an electron donating color forming compd. is used by mixing a fluorane compd. and a triphenylmethanephthalide compd.
