    摘要: A method of forming an isolated structure of sufficient size to permit the fabrication of an active device thereon is comprised of the steps of depositing a gate oxide layer on a substrate. Material, such as a polysilicon layer and a nitride layer, is deposited on the gate oxide layer to protect the gate oxide layer. An active area is defined, typically by patterning a layer of photoresist. The protective material, the layer of oxide, and finally the substrate are etched to form a trench around the active area. Spacers are formed on the sides of the active area. The substrate is etched to deepen the trench around the active area to a point below the spacers. The substrate is oxidized at the bottom of the trench and horizontally under the active area to at least partially isolate the active area from the substrate. Oxide spacers are formed on the sides of the active area to fill exposed curved oxide regions and the remainder of the trench may be filled with an oxide.

    摘要: Techniques for forming devices, such as transistors, having vertical junction edges. More specifically, shallow trenches are formed in a substrate and filled with an oxide. Cavities may be formed in the oxide and filled with a conductive material, such a doped polysilicon. Vertical junctions are formed between the polysilicon and the exposed substrate at the trench edges such that during a thermal cycle, the doped polysilicon will out-diffuse doping elements into the adjacent single crystal silicon advantageously forming a diode extension having desirable properties.

    摘要: Methods of forming field effect transistors and resultant field effect transistor circuitry are described. In one embodiment, a semiconductive substrate includes a field effect transistor having a body. A first resistive element is received by the substrate and connected between the transistor's gate and the body. A second resistive element is received by the substrate and connected between the body and a reference voltage node. The first and second resistive elements form a voltage divider which is configured to selectively change threshold voltages of the field effect transistor with state changes in the gate voltage. In a preferred embodiment, first and second diode assemblies are positioned over the substrate and connected between the gate and body, and the body and a reference voltage node to provide the voltage divider.
