Hbt process flow
Webbased electroplating process [6]. Dielectric sidewall spacers are formed that passivate the base-emitter junction and permit the formation of a self-aligned base contact. After base-contact deposition, the remaining HBT process flow follows that of a standard mesa-HBT process. The transistors are passivated WebHBT technology, in order to investigate its characteristics and performance for high frequency applications. It proves that, the technology can be widely used and can …
