Description
Dadurch, daß bei dem Back-Source-MOSFET die Sourceelektrode und die Drainelektrode getrennt auf jeweiligen (insbes. gegenüberliegenden) Hauptflächen des Wafers angeordnet sind werden das Verdrahtungsmuster vereinfacht und der Verdrahtungswiderstand deutlich verrin gert. Indem dabei ferner die Sourcezone elektrisch mit dem Substrat verbunden wird und die Sourceelektrode an der Rückseite des Substrats angeordnet wird, wird das Substratpotential stabil, so daß keine Störung in einem Logikteil zu befürchten ist, das mit dem MOSFET als Leistungsteil in einem Leistungs-IC enthalten ist.
