1. A surface treatment apparatus comprising:
- a vacuum chamber;
gas introducing means for introducing a gas into said vacuum chamber;
gas heating means for heating said gas and activating said gas to make active particles while the gas is being introduced, said gas heating means comprising a gas furnace and a heater for heating said gas furnace,gas injecting means for injecting said activated gas into said vacuum chamber to form a beam of said active particles; and
substrate holding means installed in said vacuum chamber to hold a substrate of which a surface is to be treated in a position opposite to said gas injecting means, to allow said beam to impinge on said surface in a perpendicular direction to said surface.

Abstract
A surface treatment apparatus comprising a vacuum chamber, means for introducing a gas into the vacuum chamber, a gas furnace for heating and activating the gas while it is being introduced, apertures for injecting the heated gas, and a substrate stage for holding a substrate of which the surface is to be treated by the injected gas. The gas that is heated and activated is blown onto the surface of the substrate to treat the surface without causing the surface to be damaged. Therefore, the apparatus can be employed very effectively for a process for producing semiconductor elements.
