  • Patent number: 8120135
    Abstract: A transistor has a cell array with two or more transistor cells, a temperature sensor, which is integrated in the cell array or is adjacent to the cell array, and an isolation structure. The isolation structure isolates the temperature sensor from the cell array, and has an isolation trench, which is arranged between the cell array and the temperature sensor. The distance between the temperature sensor and the active transistor cell that is closest to the temperature sensor corresponds approximately to the pitch between active transistor cells within the cell array.

  • Publication number: 20110089528
    Abstract: A semiconductor having an optimized insulation structure which is simple and inexpensive to produce and can be made smaller than LOCOS insulation structures is disclosed. An implantation mask on a surface of a semiconductor substrate is used to implant elements into the semiconductor substrate, which elements, on thermal activation, form an insulation region together with the further elements of the semiconductor substrate. The thermal activation is effected by means of laser irradiation, during which the semiconductor substrate is briefly melted and then recrystallizes during the subsequent cooling, so that the implanted elements form the insulation region together with the further elements of the semiconductor substrate.
