Title: Manufacture of semiconductor device
Inventor: AOKI HIDEMITSU
IPC: H01L23/532
Filed: 1998-05-28
Abstract: PROBLEM TO BE SOLVED: To prevent the degradation of a low-permittivity interlayer film by a method wherein the interlayer film does not come into contact with an oxygen plasma used to peel off a resist mask or with an organic isolation treatment liquid used to remove a deposit in a process in which a through hole and a wiring groove are etched by using the low-permittivity interlayer film. SOLUTION: A silicon nitride film 106 is formed on a low-permittivity interlayer film (an HSQ film) 105. The silicon nitride film 106 is patterned by using a resist mask 107. The resist mask 107 is peeled off by using an oxygen plasma. After that, the HSQ film 105 is etched by making use of the silicon nitride film 106 as a mask. In addition, before a deposit is generated, the surface of the HSQ film 105 is covered with a CVD oxide film. A deposit which is generated after that is removed by using an organic peeling liquid. The oxygen plasma and the organic peeling liquid do not come into contact with the HSQ film 105, and the degradation of the characteristic of the HSQ film 105 is prevented.  A low permittivity intrinsic to the HSQ film 105 is held, the interlayer capacitance of an interconnection can be lowered, the speed of a semiconductor device can be made high, and moisture in the film can be suppressed. As a result, the current leak of the semiconductor device can be suppressed, and the corrosion of the semiconductor device can be suppressed.
