Abstract
An insulated gate semiconductor device () includes a gate (), a source terminal (), a drain terminal () and a variable input capacitance at the gate. A ratio between the input capacitance (C) when the device is on and the input capacitance Cwhen the device is off is less than two and preferably substantially equal to one. This is achieved in one embodiment of the invention by an insulation layerat the gate having an effective thickness dlarger than a minimum thickness.
