摘要

A quantitative analysis of BPSG film flow capability with isothermal furnace and rapid thermal anneal conditions has been performed. Empirical equations are presented for calculation of BPSG film flow angles on device steps and in contact holes in a wide range of dopant concentration, film step coverage, anneal temperature and anneal time. Factors, which affect gap-fill capability of BPSG films in modern ULSI device technology are analyzed.
