    摘要: An electronic device can include a semiconductor layer overlying a substrate and having a primary surface and a thickness, wherein a trench extends through at least approximately 50% of the thickness of semiconductor layer to a depth. The electronic device can further include a conductive structure within the trench, wherein the conductive structure extends at least approximately 50% of the depth of the trench. The electronic device can still further include a vertically-oriented doped region within the semiconductor layer adjacent to and electrically insulated from the conductive structure; and an insulating layer disposed between the vertically-oriented doped region and the conductive structure. A process of forming an electronic device can include patterning a semiconductor layer to define a trench extending through at least approximately 50% of the thickness of the semiconductor layer and forming a vertically-oriented doped region after patterning the semiconductor layer to define the trench.

    摘要: A semiconductor component resistant to the formation of a parasitic bipolar transistor and a method for manufacturing the semiconductor component using a reduced number of masking steps. A semiconductor material of N-type conductivity having a region of P-type conductivity is provided. A doped region of N-type conductivity is formed in the region of P-type conductivity. Trenches are formed in a semiconductor material and extend through the regions of N-type and P-type conductivities. A field oxide is formed from the semiconductor material such that portions of the trenches extend under the field oxide. The field oxide serves as an implant mask in the formation of source regions. Body contact regions are formed from the semiconductor material and an electrical conductor is formed in contact with the source and body regions. An electrical conductor is formed in contact with the backside of the semiconductor material.
