  • POWER SEMICONDUCTOR MODULE AND DISCRETE POWER SEMICONDUCTOR DEVICE HAVING AN ACTIVE TEMPERATURE SENSOR DIE, AND CORRESPONDING METHODS OF PRODUCTION
    Publication number: 20240243042
    Abstract: A power semiconductor module includes: an electrically insulative frame; a plurality of power semiconductor dies housed within the electrically insulative frame and electrically interconnected to form a power electronics circuit; an active temperature sensor die housed within the electrically insulative frame and including an integrated current source; a first temperature sense terminal electrically connected to a first contact pad of the active temperature sensor die; and a second temperature sense terminal electrically connected to a second contact pad of the active temperature sensor die. A discrete power semiconductor device and methods of producing the module and discrete device are also described.

  • Resistor circuit
    Patent number: 11646137
    Abstract: A method of forming a resistor circuit, the method comprising forming a first resistor comprising a first type of resistor, forming a second resistor comprising a second type of resistor, the first type of resistor being different from the second type of resistor and simultaneously doping a first part of the first resistor and a second part of the second resistor, the first resistor and the second resistor being configured such that doping of the first part of the first resistor and the second part of the second resistor defines a temperature coefficient of the first resistor and a temperature coefficient of the second resistor, wherein the temperature coefficient of the first resistor and the temperature coefficient of the second resistor have opposite signs.
