Method of surface processing substrate, method of cleaning substrate, and programs for implementing the methods

摘要

A method of surface processing a substrate that enables deposit to be removed from a substrate so as to obtain a clean substrate. A substrate is cleaned with a liquid chemical. A deposit which is formed through the cleaning with liquid chemical is exposed to an atmosphere of a mixed gas containing ammonia and hydrogen fluoride under a predetermined pressure. The deposit that has been exposed to the atmosphere of the mixed gas is heated to a predetermined temperature.
