Abstract

See full text

The present invention can provide an abrasive composition for polishing a semiconductor device which composition contains water, microparticles of an abrasive, and a chelating agent, wherein the abrasive is cerium oxide; the microparticles of cerium oxide have an average particle size of 0.01-1.0 .mu.m and which composition is used for suitably forming a shallow trench isolation structure in a well-controlled manner during planarization of a semiconductor device including element-isolated structure. The invention also provides a method for producing the semiconductor device by use of the abrasive composition.
