Abstract
A processing system includes one or more processing chambers, and a system controller configured to cause the processing system to perform (a) a pre-clean process on exposed surfaces of a semiconductor structure, the semiconductor structure comprising a first semiconductor region, a second semiconductor region separated from the first semiconductor region by a trench, and a dielectric layer over at least a portion of the first semiconductor region and the second semiconductor region, (b) a first deposition process to form an amorphous silicon-containing layer on the exposed surfaces of the semiconductor structure, (c) a recrystallization anneal process to recrystallize at least a portion of the amorphous silicon-containing layer to form a silicon-containing crystalline layer within the trench, (d) an etch process to remove remaining portions of the amorphous silicon-containing layer, and (e) a second deposition process, to epitaxially form a source/drain region over the silicon-containing crystalline layer within the trench.
