This article presents a study of the issues in integrating the pattern
, fill, planarization, and surface cleanup processes to design a shall
ow trench isolation (STI) flow suitable for 0.25 mu m complementary me
tal-oxide semiconductor technologies. Technological choices and their
effects on the characteristics of the STI technology are discussed. Ex
perimental data are presented to illustrate how process choices at var
ious stages of the STI flow are made to optimize the STI structure. (C
