Abstract:
A transistor comprising:a first region of semiconductor material having a first conductivity type and a first dopant concentration, the first region having a plurality of legs that extend away from a center region to form an X shape, the plurality of legs having ends; a second region of semiconductor material having a second conductivity type and a second dopant concentration, the second region laterally contacting adjacent legs of the first region; a third region of semiconductor material having the first conductivity type and a third dopant concentration that is less than the first dopant concentration, the third region laterally contacting the second region, and contacting the first region; a fourth region of semiconductor material having the second conductivity type and a fourth dopant concentration, the fourth region laterally contacting the third region; a fifth region of semiconductor material having the second conductivity type and a fifth dopant concentration, the fifth region lying laterally adjacent to the fourth region, being electrically connected to the fourth region and spaced apart from the second region, the fifth dopant concentration being substantially equivalent to the second dopant concentration; a layer of isolation material formed on the third region; and a gate segment formed on the layer of isolation material, the gate segment being straight and formed adjacent to the ends of the adjacent legs of the first region.
