When a contact hole is formed by a dry etching process, damage is caused by the impact of the etching gas to the underlying layer, such as the element region of the semiconductor substrate, which is exposed by etching. In addition, the contact hole created by dry etching has a sharply cut shape, so
When the wiring material film is deposited, there may be no corrugated layer of the wiring material film on the side surface of the contact hole, or even if there is, it will be in a very uneven state and cause disconnection of the wiring. In addition, as a result of the formation of steep irregularities, the resolution of the resist pattern decreases, and especially when wiring is stacked in multiple layers, the irregularities become more severe, making it difficult to form fine wiring patterns.

An organic film is coated on the insulating film using a spin code method so that the surface is flat, and the organic film and the insulating film are selectively left under etching conditions with the same etching rate. 2. A method for manufacturing a semiconductor device 1d according to claim 1, wherein uniform etching is performed until fg is obtained. (5) The process of forming connection holes in the insulating film involves forming four turns of resist on the insulating film, and selectively etching the insulating film using the resist turns as a mask. Claims: 1. A method for manufacturing the semicircular body "K14" described in the first article.
