Abstract
The technology of this disclosure relates to an IGBT chip integrating a temperature sensor, and relates to the field of power device technologies, to improve accuracy of temperature monitoring of the IGBT chip. The IGBT chip integrating the temperature sensor includes a cell region, an emitter pad, a gate pad, a gate finger structure, a temperature sensing module, and a conductive shielding structure. The emitter pad is electrically connected to emitters of a plurality of IGBT cells. The gate finger structure is connected between the gate pad and gates of the plurality of IGBT cells. The temperature sensing module includes a temperature sensor, an anode pad, a cathode pad, and a metal lead. The temperature sensor and at least a part of the metal lead are located in the gate finger structure and are insulated from the gate finger structure.
