Patent ID: 7364990

Claim:
A method of manufacturing a semiconductor device, the method comprising: providing a substrate on which an insulation structure is disposed, the insulation structure having first and second openings, and on which first and second seeds are respectively exposed by the first and second openings, the first and second seeds being of a single-crystalline material; and forming a single-crystalline structure on the substrate by epitaxially growing first and second preliminary epitaxial layers on the first and second seeds, respectively, until upper portions of the first and second preliminary epitaxial layers protrude from the first and second openings, respectively, such that upper portions of the first and second preliminary epitaxial layers confront each other above the insulation structure, before the upper portions of the first and second preliminary epitaxial layers are connected directly to each other above the insulation structure, performing a deposition process comprising selectively forming material having an amorphous state on the insulation structure in between the unconnected portions of the first and second preliminary epitaxial layers, and growing the material having an amorphous state such that a preliminary connection structure of the material having an amorphous state contacts lower portions of the first and second preliminary epitaxial layers before the upper portions of the first and second preliminary epitaxial layers are connected, and forming a connection structure by transforming the material of the preliminary connection structure having an amorphous state into a single-crystalline material.
