Abstract

A method for manufacturing a semiconductor device includes: forming a protrusion-patterned layer on a substrate, the protrusion-patterned layer including a plurality of separated protrusions, each of which includes a base portion formed on the substrate and a top end portion opposite to the base portion; laterally growing a base layer on the top end portions of the protrusions of the protrusion-patterned layer in such a manner that each of the top end portions is covered by the base layer and that the base layer cooperates with the protrusions to define a plurality of cavities thereamong; thickening the base layer to a predetermined layer thickness; and separating the base layer from the substrate by destroying the protrusions of the protrusion-patterned layer.
