    摘要: A method for forming a transistor having insulated gate electrodes and insulated shield electrodes within trench regions includes forming dielectric stack overlying a substrate. The dielectric stack includes a first layer of one material overlying the substrate and a second layer of a different material overlying the first layer. Trench regions are formed adjacent to the dielectric stack. After the insulated shield electrodes are formed, the method includes removing the second layer and then forming the insulated gate electrodes. Portions of gate electrode material are removed to form first recessed regions, and dielectric plugs are formed in the first recessed regions using the first layer as a stop layer. The first layer is then removed, and spacers are formed adjacent the dielectric plugs. Second recessed regions are formed in the substrate self-aligned to the spacers.

    摘要: A semiconductor component that includes a field plate and a semiconductor device and a method of manufacturing the semiconductor component. A semiconductor material includes an epitaxial layer disposed on a semiconductor substrate. A trench having an upper portion and a lower portion is formed in the epitaxial layer. A portion of a field plate is formed in the lower portion of the trench, wherein the field plate is electrically isolated from trench sidewalls. A gate structure is formed in the upper portion of the trench, wherein a gate oxide is formed from opposing sidewalls of the trench. Gate electrodes are formed adjacent to the gate oxide formed from the opposing sidewalls and a dielectric material is formed adjacent to the gate electrode. Another portion of the field plate is formed in the upper portion of the trench and cooperates with the portion of the field plate formed in the lower portion of the trench to form the field plate.

    摘要: In one embodiment, an edge seal region of a semiconductor die is formed by forming a first dielectric layer on a surface of a semiconductor substrate near an edge of the semiconductor die and extending across into a scribe grid region of the semiconductor substrate. Another dielectric layer is formed overlying the first dielectric layer. An opening is formed through the first and second dielectric layers. The second dielectric layer is used as a mask for forming a doped region on the semiconductor substrate through the opening. A metal is formed that electrically contacts the doped region and an exterior edge of the first dielectric layer within the opening.
