Title: Insulating film on base and method for manufacturing the same
Inventor: MIYAKAI TAMON
IPC: H01L27/12
Filed: 2002-03-06
Abstract: <P>PROBLEM TO BE SOLVED: To obtain a low-dielectric-constant film which has superior mechanical strength as compared with a general low-dielectric-constant material as an insulating film on a base.  <P>SOLUTION: A low-dielectric-constant insulating film structure is obtained by providing a silicon oxide film 12 on a lower-layer structure 10 across an Sin film 11 as an etching stopper, digging a large number of holes 14 by etching using a photoresist of a honeycomb pattern as a mask, and charging a low- dielectric-constant insulating material in holes 15 of the honeycomb-shaped silicon oxide film 12a which are increased in diameter by etching. Although the low-dielectric-constant insulating material to be charged has low mechanical strength, the honeycomb-shaped silicon oxide film 12a has mechanical strength and then the low-dielectric-constant film structure has superior mechanical strength. Consequently, the insulating film can withstand CMP pressure, for example, when a wire is formed by digging a wiring groove in the low-dielectric- constant insulating film structure, forming a copper layer by an electrolytic plating method, and removing excessive copper flatly by CMP.  <P>COPYRIGHT: (C)2003,JPO
