Abstract
PURPOSE:To improve yield in case of production by a method wherein insulating films are formed in steps that are divided at least twice, contact holes are formed every formation, and the disconnection of metallic wiring is prevented by the difference in level. CONSTITUTION:A silicon oxide film 6 is deposited on a surface of substrate silicon 5 by means of a CVD method. The thickness of the oxide film at that time is made approximate half of the thickness of the final oxide film. A resist film 7 is formed for etching a contact hole, the desired pattern in made up, and the contact hole is etched first. All the resist film 7 is removed after etching, and an oxide film 8 is built up again on the whole surface in the same manner as the preceding time. The sum of the oxide film 7, 8 is made the thickness of an oxide film finally necessary for the protection of the surface. A contact hole is etched and the resist is exfoliated in the same manner as mentioned above.
