  • Publication number: 20140042551
    Abstract: SRAM ICs and methods for their fabrication are provided. One method includes depositing photoresist on a first oxide layer overlying a silicon substrate, forming a pattern of locations, using said photoresist, for the formation of two inverters, each having a pull up transistor, a pull down transistor, and a pass gate transistor on said oxide layer. The method involves anisotropically etching U-shaped channels in the oxide layer corresponding to pattern, and thereafter isotropically etching U-shaped channels in the silicon layer to form saddle-shaped fins in the silicon. A second oxide layer is deposited over the saddle-shaped fins, and a first metal layer is deposited over the second oxide layer. A contact metal layer is formed over the first metal layer and planarized to form local interconnections coupling the gate electrodes of one inverter to a node between the pull up and pull down transistors of the other inverter and to a source/drain of one of the pass gate transistors.

  • Patent number: 8575013
    Abstract: Semiconductor devices and related fabrication methods are provided. An exemplary fabrication method involves forming a pair of gate structures having a dielectric region disposed between a first gate structure of the pair and a second gate structure of the pair, and forming a voided region in the dielectric region between the first gate structure and the second gate structure. The first and second gate structures each include a first gate electrode material, wherein the method continues by removing the first gate electrode material to provide second and third voided regions corresponding to the gate structures and forming a second gate electrode material in the first voided region, the second voided region, and the third voided region.

  • Publication number: 20130193516
    Abstract: SRAM ICs and methods for their fabrication are provided. One method includes forming dummy gate electrodes overlying a semiconductor substrate and defining locations of gate electrodes for two cross coupled inverters and two pass gate transistors. A first insulating layer is deposited overlying the dummy gate electrodes and gaps between the dummy gate electrodes are filled with a second insulating layer. The second insulating layer is etched to form inter-gate openings exposing portions of the substrate. The first insulating layer is etched to reduce the thickness of selected locations thereof, and the dummy gate electrodes are removed. A gate electrode metal is deposited and planarized to form gate electrodes and local interconnections coupling the gate electrodes of one inverter to a node between the pull up and pull down transistors of the other inverter and to a source/drain of one of the pass gate transistors.

  • Publication number: 20130137234
    Abstract: Methods are provided for forming semiconductor devices. One method includes etching trenches into a silicon substrate and filling the trenches with an insulating material to delineate a plurality of spaced apart silicon fins. Dummy gate structures are formed, which includes a first dummy gate structure, that overlie and are transverse to the fins. A back fill material is filled between the dummy gate structures. The first dummy gate structure and an upper portion of the insulating material are removed to expose an active fins portion of the fins. The active fins portion is dimensionally modified to form an altered active fins portion. A high-k dielectric material and a work function determining gate electrode material are deposited overlying the altered active fins portion.
