|20110045664||TRANSISTOR STRUCTURE HAVING A TRENCH DRAIN - A semiconductor device is formed having a trench adjacent to a current carrying region of the device. The trench is formed having a depth greater than the depth of a tub region of the device. Increasing the trench depth moves a region of higher field strength from the tub region to a region along the trench. The region along the trench does not have a junction and may withstand the higher field strength.||02-24-2011|
