An advanced, high-performance 4-inch InP HBT process technology has been offered for commercial pure-play foundry services by GCS for the last two years. In this paper, we reported on recent advances of our proprietary device design and process technology, GCS’s InP HBTs show potentially excellent reliability under lifetests at current densities of 100kA/cm 2 and higher. State-of –the-art circuit performances have been demonstrated by our customers designing into our baseline InP HBT process technology; which we believed are strong evidences of the readiness of InP HBT technology for mainstream IC production.
