Abstract |
AB |
[EN] A power semiconductor device includes a first contact, a second contact, and a semiconductor volume disposed between the first contact and the second contact. The semiconductor volume includes an n-doped field stop layer configured to spatially delimit an electric field that in the semiconductor volume during operation of the power semiconductor device, a heavily p-doped zone and a neighboring heavily n-doped zone, which together form a tunnel diode. The tunnel diode is located in the vicinity of, or adjacent to, or within the field stop layer. The tunnel diode is configured to provide protection against damage to the device due to a rise of an electron flow in an abnormal operating condition, by the fast provision of holes. Further, a method for producing such devices is provided. |
