Abstract

A method of modifying a surface of a body such as a semiconductor body is described in which a beam of electromagnetic radiation is directed towards the surface so that the electromagnetic radiation is incident on the surface at or near the Brewster angle, the electromagnetic radiation incident on the surface preferably being so polarised that the electric vector of the electromagnetic radiation lies in the plane of incidence of the electromagnetic radiation at the surface.
