Abstract: The gate capacitance of a Field effect transistor (24) used as a switch is rapidly charged via a diode (35) to turn the FET on, and is rapidly discharged to turn the FET off by a switching transistor (36) connected across the diode and the FET such that it becomes conductive only when the diode becomes reverse biased, thereby providing a discharge path for the gate capacitance. The circuit is used in a photovoltaic relay, the FET being turned on by a photovoltaic isolator (20) having a LED 21 energised by an input signal optically coupled to and dielectrically isolated from a series-connected stack of photo diodes connected to the switching FET, which may comprise a bilateral semiconductor FET (BOSFET).

Abstract: An auxiliary MOSFET is integrated into a lateral IGBT structure with the source and drain of the auxiliary MOSFET in parallel with the emitter-base circuit of the IGBT. A driver, integrated with the IGBT chip, turns off the base emitter voltage to the IGBT before turning off the auxiliary MOSFET during turn off. The auxiliary MOSFET is turned off again at the beginning of the conduction period to ensure full conductivity modulation of the DMOS drain and maximum gain of the PNP transistor. Short circuit protection and overtemperature protection circuits are also integrated into the chip.

Abstract: A reduced mask process for forming a MOS gated device such as a power MOSFET uses a first mask (33) to sequentially form a cell body (50) and a source region (51) within the cell body (50), and a second mask step to form, by a silicon etch, a central opening (80,81) in the silicon surface at each cell and to subsequently undercut the oxide (60) surrounding the central opening (80,81). A contact layer (84) then fills the openings (80,81) of each cell to connect together the body (50) and source regions (51). Only one critical mask alignment step is used in the process.
