Title: Insulating film flattening method
Inventor: NAKAJIMA HIDEHARU
IPC: H01L21/316
Filed: 1995-09-19
Abstract: PROBLEM TO BE SOLVED: To provide an insulating film flattening method with which both local flattening and global flattening can be accomplished simultaneously. SOLUTION: First, an SOG film 4b is thckly covered on a CVD interlayer insulating film 3 which conformably covers an Al wiring pattern 2. At this time, the condition of local flattening is satisfied by setting the thickness of the SOG film 4b in such a manner that its lowest altitude part becomes higher than the highest altitude part of the CVD interlayer insulating film 3. Then, said SOG film 4b is flattened by a pure physical mechanism, having no chemical structure, such as the cutting by a cutting blade or by a wiping blade. The above-mentioned cutting operation is conducted after baking of the SOG film 4, and the wiping operation is conducted before the baking of the SOG film 4b.  As the CVD interlayer insulating film 3 has the hardness higher than the SOG film 4b, the cutting and the wiping operation is stopped at the highest altitude part of the CVD interlayer insulating film 3, and the global flattening can be accomplished.

Abstract: PURPOSE:To enable an insulation thin film of uniformity and good quality to be formed over the whole sample having a large diameter, by a method wherein the cathode is so constructed as to be in the form of a disc made of the same substance as that of the sample. CONSTITUTION:The disc electrode 8 is as large as a sample table 5 or the sample mounted on the sample table 5.
