摘要： A method for treating a copper surface of a semiconductor device provides exposing the copper surface to a citric acid solution after the surface is formed using CMP (chemical mechanical polishing) or other methods. The citric acid treatment may take place during a cleaning operation that takes place in a wafer scrubber, or subsequent to such an operation. The citric acid treatment removes copper oxides that form on copper surfaces exposed to the environment and prevents hillock formation during subsequent high temperature operations. The copper surface is then annealed and the annealing followed by an NH3 plasma treatment which again removes any copper oxides that may be present. The NH3 plasma operation roughens exposed surfaces improving the adhesion of subsequently-formed films such as a dielectric film preferably formed in-situ with the NH3 plasma treatment. The subsequently-formed film is formed over an oxide-free, hillock-free copper surface.

摘要： A method of forming a silicon oxide, shallow trench isolation (STI) region, featuring a silicon rich, silicon oxide layer used to protect the STI region from a subsequent wet etch procedure, has been developed. The method features depositing a silicon oxide layer via PECVD procedures, without RF bias, using a high silane to oxygen ratio, resulting in a silicon rich, silicon oxide layer, located surrounding the STI region. The low etch rate of the silicon rich, silicon oxide layer, protect the silicon oxide STI region from buffered hydrofluoric wet etch procedures, used for removal of a dioxide pad layer.
