Patent ID: 8278194

Claim:
A method for fabricating semiconductor devices, comprising: (a) forming over a temporary substrate a sacrificial film layer having a plurality of spaced apart sacrificial film portions, which expose partially the temporary substrate; (b) growing laterally and epitaxially an epitaxial film layer over the sacrificial film layer and the temporary substrate; (c) forming over the epitaxial film layer a patterned mask that covers partially the epitaxial film layer and that defines a plurality of through holes to expose a plurality of epitaxial surface regions, respectively; (d) forming a plurality of conductive members respectively in the through holes and on the epitaxial surface regions; (e) removing the patterned mask and removing apart of the epitaxial film layer and a part of the sacrificial film layer beneath the patterned mask until a portion of the temporary substrate therebeneath is exposed, thereby forming gaps among the conductive members and dividing the epitaxial film layer into a plurality of epitaxial structures; (f) removing the sacrificial film layer by wet etching; and (g) after the step (f), removing the temporary substrate by wet etching.
