Abstract:
One or more embodiments relate to a method of making a heterojunction bipolar transistor (HBT) structure. The method includes: forming a partially completed heterojunction bipolar transistor (HBT) structure where the partially completed heterojunction bipolar transistor (HBT) structure includes a silicon layer having an exposed surface and a nitride layer having an exposed surface. The method includes growing a first oxide on the silicon layer and etching the nitride layer using an etchant.
