发明名称 PLASMA PROTECTION DIODE FOR A HEMT DEVICE
摘要 A silicon substrate having a III-V compound layer disposed thereon is provided. A diode is formed in the silicon substrate through an ion implantation process. The diode is formed proximate to an interface between the silicon substrate and the III-V compound layer. An opening is etched through the III-V compound layer to expose the diode. The opening is filled with a conductive material. Thereby, a via is formed that is coupled to the diode. A High Electron Mobility Transistor (HEMT) device is formed at least partially in the III-V compound layer.
