A microscopic interconnection pattern and a gate electrode can be prevented from being deformed when a first region requiring high temperature heating, such as a source-drain region and a second region which should be prevented from being heated at high temperature, such as a microscopic interconnection pattern and a gate electrode are formed on the same semiconductor substrate. A first region which requires high temperature heating and a second region which should be avoided from being heated at high temperature are formed on a semiconductor substrate. In that case, the second region is composed of a narrow portion (1) and wide portions (2) wider than the narrow portion (1) formed on respective ends of the narrow portion 1. Then, the semiconductor substrate is photo-annealed.
