  • Power trench DMOS with large active cell density
    Patent number: 5981999
    Abstract: A design for a trench DMOS transistor having improved current carrying capability is presented. The principal improvement lies in the periodic replacement of the individual cells in the array with a protection cell of a different size. When this is done it becomes possible to significantly increase the density of cells per unit area. This results in a corresponding improvement in the amount of channel area available to the device and hence an increase in its current carrying capability.
