WebHBT process, with minor metal, and etch chemistry differences, Similarly, the InP HEMT process has much similarity to the GaAs HEMT technologies. The InP backside ... WebHBT process [2,3]. The 4th generation HBT process, so called HBT4, includes two interconnection metal layers (M1 and M2) and a thicker SiN layer as the dielectric layer between M1 and M2. A thicker SiN film instead of using Polyimide as dielectric film can provide better mechanical and moisture protection.
