    摘要: The specification and drawings present a new method, device and computer/software related product (e.g., a computer readable memory) are presented for realizing eDRAM strap formation in Fin FET device structures. Semiconductor on insulator (SOI) substrate comprising at least an insulator layer between a first semiconductor layer and a second semiconductor layer is provided. The (metal) strap formation is accomplished by depositing conductive layer on fins portion of the second semiconductor layer (Si) and a semiconductor material (polysilicon) in each DT capacitor extending to the second semiconductor layer. The metal strap is sealed by a nitride spacer to prevent the shorts between PWL and DT capacitors.

    摘要: FinFETS and methods for making FinFETs with a recessed stress liner. A method includes providing an SOI substrate with fins, forming a gate over the fins, forming an off-set spacer on the gate, epitaxially growing a film to merge the fins, depositing a dummy spacer around the gate, and recessing the merged epi film. Silicide is then formed on the recessed merged epi film followed by deposition of a stress liner film over the FinFET. By using a recessed merged epi process, a MOSFET with a vertical silicide (i.e. perpendicular to the substrate) can be formed. The perpendicular silicide improves spreading resistance.

    摘要: A method for fabricating a field effect transistor device includes patterning a semiconductor fin on a substrate insulator layer, the substrate insulator layer arranged on a substrate, patterning a dummy gate stack over a portion of the fin, forming spacers adjacent to the dummy gate stack, removing the dummy gate stack to form a cavity that exposes portions of the substrate insulator layer and the fin, removing exposed portions of the substrate insulator layer to increase a depth of the cavity, removing a region of the substrate insulator layer from beneath the fin to suspend a portion of the fin above the substrate insulator layer, forming a gate stack in the cavity, removing a portion of the gate stack in the cavity to expose a portion of a dielectric layer arranged on the fin, and depositing an insulator material in the cavity.
