Abstract:
1. A method for manufacturing a semiconductor element comprising: forming a base film over a glass substrate; forming a semiconductor film over the base film; forming an oxide film or a nitride film over a surface of the semiconductor film by radical oxidation or radical nitridation of the semiconductor film, at a temperature of the glass substrate lower than a strain point of the glass substrate by 100° C. or more; forming a film for preventing oxidation or nitridation of the semiconductor film over the oxide film or the nitride film; forming the oxide film or the nitride film and the film for preventing oxidation or nitridation each into a predetermined pattern; and performing an element isolation by radical oxidation or radical nitridation of a region of the semiconductor film at a temperature of the glass substrate lower than the strain point of the glass substrate by 100° C. or more, wherein the region is not covered with the predetermined pattern, and wherein the radical oxidation or the radical nitridation is performed over the semiconductor film placed apart from a plasma generation region in a plasma treatment chamber with an electron temperature of from 0.5 eV to 1.5 eV, and anelectron density of from 1×10
