Filed: 1998-09-15
Abstract: PROBLEM TO BE SOLVED: To flatten the surface of silicon at atomic layer level in an actual LSI manufacturing process by flattening the surface of the silicon at the atomic layer level by heat-treating the silicon in an atmosphere containing atomic hydrogen. SOLUTION: In a method of flattening the surface of silicon, an atmosphere containing a large amount of atomic hydrogens generated by thermionic emission from a metallic filament, making contact with the metallic filament, etc., is formed and silicon is heat-treated in the atmosphere. There is no nud at all to use a high temperature such as 1,000 deg.C or higher as the heat-treating temperature of the silicon, and moreover the heat-treating temperature may be 1,000 deg.C or lower, and furthermore about 900 deg.C or lower. In addition, when atomic hydrogen is generated in a silicon treating space or supplied to the space after the hydrogen is generated, it is necessary to prevent the mixture of impurities in the hydrogen as much as possible. Thus, planarization of a silicon metal can be made at atomic layer level under low-temperature conditions.
