  • Monolithic semiconductor switches and method for manufacturing
    Patent number: 8193559
    Abstract: One aspect is monolithic semiconductor switches and method for manufacturing. One embodiment provides a semiconductor die with a first n-type channel FET and a second n-type channel FET. A source of the first n-type channel FET and a drain of the second n-type channel FET are electrically coupled to at least one contact area at a first side of the semiconductor die, respectively. A drain of the first n-type channel FET, a gate of the first n-type channel FET, a source of the second n-type channel FET and the gate of the second n-type channel FET are electrically coupled to contact areas at a second side of the semiconductor die opposite to the first side, respectively. The contact areas of the drain of the first n-type channel FET, of the gate of the first n-type channel FET, of the source of the second n-type channel FET and of the gate of the second n-type channel FET are electrically separated from each other, respectively.
