Abstract:
Semiconductor structures and methods of manufacture semiconductors are provided which relate to heterojunction bipolar transistors. The structure includes two devices connected by metal wires on a same wiring level. The metal wire of a first of the two devices is formed by selectively forming a metal cap layer on copper wiring structures.
