Patent ID: 7394135

Claim:
A dual source metal oxide silicon field effect transistor comprising a plurality of cells, each of the plurality of cells comprising a gate, and insulation layer, and a channel, the channel comprising a source and a drain, the plurality of cells being diffused into a common drain substrate having a common drain connection for connecting all of the drains of the plurality of cells to an external power circuit, the plurality of cells being divided into a first group of cells having a common first source connection connecting together all of the sources of the first group of cells and having a common first gate connection connecting together all of the gates of the first group of cells and a second group of cells having a common second source connection connecting together all of the sources of the second group of cells and having a common second gate connection connecting together all of the gates of the second group of cells, the number of cells in the first group of cells being essentially equal to the number of cells in the second group of cells, the common first source connection and the common second source connection being for connecting respectively to the external power circuit, the common first gate connection and the common second gate connection being for connecting respectively to first and second control and gate drive circuits, and the common first source connection and the common second source connection being highly interdigitated.
