摘要:
A method of smoothening a surface of a semiconductor structure comprises exposing the surface of the semiconductor structure to a reactant. A chemical reaction between a material of the semiconductor structure and the reactant is performed. In the chemical reaction, a layer of a reaction product is formed on at least a portion of the surface of the semiconductor structure. The layer of the reaction product is selectively and completely removed.
