Title: Manufacture of semiconductor device
Inventor: SATO SEIICHI
IPC: G03F7/00
Filed: 1987-08-26
Abstract: PURPOSE:To prevent an intermediate layer and an upper layer resist film from mixing in a boundary therebetween even if a lower layer resist film and the intermediate layer are heat treated at a low temperature by forming an oxide film by oxygen plasma processing or sputtering on the intermediate layer and then forming a resist film. CONSTITUTION:A lower layer resist film 2 is formed on a second aluminum wiring layer 1 on an interlayer insulating film 6. Then, the surface is coated with spin-on glass (SOG) to form an intermediate layer 3. Then, the film 2 and the layer 3 are heat treated at 170 deg.C necessary for curing a resist. The film 2 is cured at this temperature, but the SOG of the layer 3 is not completely cured. Thereafter, an oxygen reactive ion etching is conducted by an anisotropic etching unit to form a silicon oxide film 4 on the layer 3. Further, since the film 4 becomes a barrier even if it is further coated with the resist to become an upper layer resist film 5, the SOG is not dissolved by the action of the solvent of the resist thereby to eliminate the possibility of mixing with the film 5.

Filed: 1985-09-30
Abstract: PURPOSE:To eliminate the necessity of rewriting so as to shorten sharply the time required for making shifting work when the mode is changed, by recording the mode when recording is made to the record on a track. CONSTITUTION:The information processing system of this invention is composed of a central processor 1, channel 2, disk controller, string controller 4, and plural disk storage devices 5.
