    摘要: The disclosure includes preferred semiconductor transistor devices utilizing thin film transistors, as well as preferred methods of forming such devices. Specifically, a bottom thin film transistor gate is formed having a top surface. An insulating filler is provided adjacent the thin film transistor gate to an elevation at least as high as the thin film transistor gate top surface, and subsequently levelled to provide generally planar insulating surfaces adjacent the thin film transistor gate. The planar insulating surfaces are substantially coplanar with the thin film transistor gate top surface. A planar semiconductor thin film is then formed over the thin film transistor gate and over the adjacent planar insulating surfaces. The thin film is doped to form source and drain regions of a thin film transistor which is bottom gated by the thin film transistor gate.

    摘要: A method for forming semiconductor devices includes a low energy implant for tailoring the electrical characteristics of the semiconductor devices. Using the low energy implant, narrow width devices such as access transistors in an SRAM cell, can be fabricated with a low threshold voltage (Vt). The low energy implant is performed on the active areas of a silicon substrate following field isolation and field implant. For an n-conductivity access transistor, the low energy dopant can be an n-type dopant such as phosphorus, arsenic or antimony.

    摘要: A thin film phase change memory may be provided with a layer which changes between amorphous and crystalline states. The threshold voltage of that layer may be increased in a variety of fashions. As a result of the threshold increase, it is possible to transition cells, initially fabricated in the set or low resistance state, into the reset or high resistance state. In one advantageous embodiment, after such initialization and programming, the threshold voltage increase is eliminated so that the cells operate thereafter without the added threshold voltage.

    摘要: A process is provided for forming vertical contacts in the manufacture of integrated circuits and devices. The process eliminates the need for precise mask alignment and allows the etch of the contact hole to be controlled independent of the etch of the interconnect trough. The process includes forming an insulating layer on the surface of a substrate; forming an etch stop layer on the surface of the insulating layer; forming an opening in the etch stop layer; etching to a first depth through the opening in the etch stop layer and into the insulating layer to form an interconnect trough; forming a photoresist mask on the surface of the etch stop layer and in the trough; and continuing to etch through the insulating layer until reaching the surface of the substrate to form a contact hole. The above process may be repeated during the formation of multilevel metal integrated circuits.
