Cleaning composition, method for cleaning semiconductor substrate, and process for manufacturing semiconductor device

摘要

The cleaning composition which comprises organic polymer particles (A) having a crosslinked structure and a surfactant (B) and is used after chemical mechanical polishing. The cleaning method of a semiconductor substrate is a method for cleaning semiconductor substrate given after chemical mechanical polishing, by the use of the cleaning composition. The process for manufacturing a semiconductor device including a step of chemically and mechanically polishing a semiconductor substrate and a step of cleaning the semiconductor substrate obtained after the chemical mechanical polishing, by the cleaning method.
