In one embodiment, a method for forming a transistor having insulated gate electrodes and insulated shield electrodes within trench regions includes forming disposable dielectric stack overlying a substrate. The method also includes forming the trench regions adjacent to the disposable dielectric stack. After the insulated gate electrodes are formed, the method includes removing the disposable dielectric stack, and then forming spacers adjacent the insulated gate electrodes. The method further includes using the spacers to form recessed regions in the insulated gate electrodes and the substrate, and then forming enhancement regions in the first and second recessed regions.

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.

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.

In one embodiment, a vertical insulated-gate field effect transistor includes a shield electrode formed in trench structure within a semiconductor material. A gate electrode is isolated from the semiconductor material using gate insulating layers. Before the shield electrode is formed, spacer layers can be used form shield insulating layers along portions of the trench structure. The shield insulating layers are thicker than the gate insulating layers. In another embodiment, the shield insulating layers have variable thickness.
