  • Publication number: 20190221489
    Abstract: In order to address the problem in that, by increasing the gate resistance of a power semiconductor element, while variation of switching time can be controlled, loss due to the gate resistance becomes larger and power efficiency for the entire system is lowered, the present invention provides an insulating substrate capable of uniformizing switching speeds of circuit elements while suppressing influence on power efficiency of the circuit elements. In the insulating substrate according to the present invention, part of a wiring layer is formed as a control signal circuit layer, and part of the control signal circuit layer is formed as a resistance layer that increases input resistance when the circuit element receives a control signal.

  • Patent number: 10084052
    Abstract: In a semiconductor device, a gate insulating film is provided with a multi-layer structure including a first insulating film and a second insulating film. The first insulating film is formed of an insulating film containing an element having an oxygen binding force larger than that of an element contained in the second insulating film, and the total charge amount is increased. Specifically, by performing oxygen anneal, it is possible to perform the step of supplying oxygen into an aluminum oxide film and increase the total charge amount. This allows a negative fixed charge density in the gate insulating film in the vicinity of an interface with a GaN layer to be set to a value of not less than 2.5×1011 cm?2 and allows a normally-off element to be reliably provided.
