ABSTRACT:
A convenient method of depositing chemical protection material on the surface of a semiconductor substrate whereby deposition of contaminating substances after a clean surface has been obtained can be prevented and maintaining of this surface performed includes a process of depositing a high molecular straight-chain organic compound3onto a highly clean surface2of a semiconductor substrate1during semiconductor washing or after semiconductor washing of the semiconductor substrate.
