Abstract:
A terminal structure of an insulated gate bipolar transistor (IGBT) device includes a main junction, a cutoff ring, and a plurality of terminal rings disposed between the main junction and the cutoff ring, and a resistive element having a first terminal electrically connected to the main junction, a second terminal electrically connected to the cutoff ring, and a plurality of intermediate terminals electrically connected to the terminal rings, respectively. The resistive element is configured to uniformly distribute the lateral voltage between the main junction and the cutoff ring to the terminal rings to ensure that the peak electric field is uniformly distributed across the terminal structure, thereby reducing the terminal structure area and package cost of the IGBT device, while improving the device reliability

Claim (Index 5):
The terminal structure of  claim 2 , wherein the resistive element comprises a regular shaped resistive material layer such that the voltage between the main junction and the cutoff ring is uniformly distributed across the resistive element when the IGBT device is under normal operating conditions.
