Abstract
Techniques for semiconductor devices including amorphous silicon are disclosed. In the illustrative embodiment, trenches are etched through several layers of a memory during manufacture, including through a phase-change layer. To protect the phase-change layer during further processing steps, amorphous silicon is applied to the phase-change layer using low-temperature chemical vapor deposition, which can be done without exceeding the melting point of the phase-change layer. The amorphous silicon can be oxidized, forming a protective silicon oxide layer around the phase-change layer.
