摘要:
The layers of a semiconductor device have exposed edges. The layers that are susceptible to oxidation are protected from oxidation by coating them with a nitride passivation layer. The nitride passivation layer can be applied using plasma enhanced chemical vapor deposition (PECVD). A method of making a passivated sidewall semiconductor includes the steps of applying a nitride or other protective material over a wafer using PECVD or other appropriate deposition method.
摘要:
Antimony-based semiconductor devices are formed over a substrate structure (10) that includes an antimony-based buffer layer (24) and an antimony-based buffer cap (26). Multiple epitaxial layers (30–42) formed over the substrate structure (10) are dry etched to form device mesas (12) and the buffer cap (26) provides a desirably smooth mesa floor and electrical isolation around the mesas.
