First Claim
Patent Images
1. A method of fabricating a semiconductor substrate, themethod comprising:
- forming a plurality of semispherical protrusions at an interval on a first plane of a substrate;
forming a first semiconductor layer on the first plane of the substrate;
forming a metallic material layer comprising a pattern of shapes on a first surface of the first semiconductor layer opposite to the first plane of the substrate; and
forming a second semiconductor layer on the first surface of the first semiconductor layer using metal organic chemical vapor deposition to form cavities in portions of the first semiconductor layer adjoining the metallic material layer.

Abstract
Disclosed are a flat and thin semiconductor substrate, which is formed on a heterogeneous substrate to be easily lifted-off from the heterogeneous substrate, a semiconductor device including the same, and a method of fabricating the same. The semiconductor substrate includes a substrate having a plurality of semispherical protrusions arranged at a predetermined interval on a first plane, and a first semiconductor layer formed on the first plane of the substrate.
