    摘要: A static RAM cell may be formed on the basis of two double channel transistors and a select transistor, wherein a body contact may be positioned laterally between the two double channel transistors in the form of a dummy gate electrode structure, while a further rectangular contact may connect the gate electrodes, the source regions and the body contact, thereby establishing a conductive path to the body regions of the transistors. Hence, compared to conventional body contacts, a very space-efficient configuration may be established so that bit density in static RAM cells may be significantly increased.

    摘要: By forming a non-oxidizable liner in an isolation trench and selectively modifying the liner within the isolation trench, the stress characteristics of the isolation trench may be adjusted. In one embodiment, a high compressive stress may be obtained by treating the liner with an ion bombardment and subsequently exposing the device to an oxidizing ambient at elevated temperatures, thereby incorporating silicon dioxide into the non-oxidizable material. Hence, an increased compressive stress may be generated within the non-oxidizable layer.

    摘要: A selective stress memorization technique is disclosed in which the creation of tensile strain may be accomplished without additional photolithography steps by using an implantation mask or any other mask required during a standard manufacturing flow, or by providing a patterned cap layer for a strained re-crystallization of respective drain and source areas. In still other aspects, additional anneal steps may be used for selectively creating a crystalline state and a non-crystalline state prior to the re-crystallization on the basis of a cap layer. Thus, enhanced strain may be obtained in one type of transistor while not substantially negatively affecting the other type of transistor without requiring additional photolithography steps.

    摘要: A stressed MOS device and a method for its fabrication are provided. The MOS device comprises a substrate having a surface, the substrate comprising a monocrystalline semiconductor material having a first lattice constant. A channel region is formed of the monocrystalline silicon material adjacent the surface. A stress inducing monocrystalline semiconductor material having a second lattice constant greater than the first lattice constant is grown under the channel region to exert a horizontal tensile stress on the channel region.
