  • Publication number: 20060234428
    Abstract: Enhanced silicon-on-insulator (SOI) buried oxide (BOX) structures and methods are provided for implementing enhanced SOI BOX structures. An oxygen implant step is performed from a backside into a thinned silicon substrate layer. An anneal step forms thick buried oxide (BOX) regions from oxygen implants in the silicon substrate layer. The oxygen implant step forms an isolated region near the oxygen implants. A backside implant step selectively dopes the isolated region for forming a backgate for an SOI device being formed including a selected one of anti-fuse (AF) devices, and SOI transistors including PFET and NFET devices.

    Abstract: Standard photolithography is used to pattern and fabricate a final polysilicon wafer imaged structure which is smaller than normal allowable photo-lithographic minimum dimensions. Three different methods are provided to produce such sub-minimum dimension structures, a first method uses a photolithographic mask with a sub-minimum space between minimum size pattern features of the mask, a second method uses a photolithographic mask with a sub-minimum widthwise jog or offset between minimum size pattern features of the mask, and a third method is a combination of the first and second methods.

  • Publication number: 20060145356
    Abstract: A method and structure for forming an integrated circuit chip that forms thermal conductors in a second wafer, and bonds the second wafer to a first wafer. Then circuits are formed in the first wafer. The thermal conductors in the second wafer have a higher coefficient of thermal conductivity than the second wafer and the bonding process seals the thermal conductors within the second wafer. Chip carrier connections are formed on the side of the first wafer that is opposite to the side where the first wafer is bonded to the second wafer, and then the first wafer can be bonded to a chip carrier. The second wafer has a coefficient of thermal expansion that matches a coefficient of thermal expansion of the first wafer.

  • Publication number: 20060128071
    Abstract: A method is described for fabricating and antifuse structure (100) integrated with a semiconductor device such as a FINFET or planar CMOS devise. A region of semiconducting material (11) is provided overlying an insulator (3) disposed on a substrate (10); an etching process exposes a plurality of corners (111-114) in the semiconducting material. The exposed corners are oxidized to form elongated tips (111t-114t) at the corners; the oxide (31) overlying the tips is removed. An oxide layer (51), such as a gate oxide, is then formed on the semiconducting material and overlying the corners; this layer has a reduced thickness at the corners. A layer of conducting material (60) is formed in contact with the oxide layer (51) at the corners, thereby forming a plurality of possible breakdown paths between the semiconducting material and the layer of conducting material through the oxide layer.

  • Publication number: 20060060938
    Abstract: A resettable fuse device is fabricated on one surface of a semiconductor substrate (10) and includes: a gate region (20) having first and second ends; a source node (81) formed in proximity to the first end of the gate region; an extension region (52) formed to connect the source node to the first end of the gate region; and a drain node (80) formed in proximity to the second end of the gate region and separated from the gate region by a distance (D) such that upon application of a predetermined bias voltage to the drain node a connection between the drain node and the second end of the gate region is completed by junction depletion. A gate dielectric (30) and a gate electrode (40) are formed over the gate region. Current flows between the source node and the drain node when the predetermined bias is applied to both the drain node and the gate electrode.

  • Publication number: 20050275054
    Abstract: A thermal monitor diode is provided that comprises a silicon thin film on an insulator mounted on a silicon substrate. An opening extends through the silicon thin film and through the insulator and partially into the silicon substrate and terminates at an end wall. A conductive material is disposed in the opening and extends to the end wall. The substrate has a P/N junction formed therein adjacent the end wall, and an insulating spacer material surrounds the conductive material and is sufficiently thin to allow temperature excursions in the silicon thin film to pass therethrough. The invention also contemplates a method of forming the diode.

  • Publication number: 20050266652
    Abstract: A structure, apparatus and method for utilizing vertically interdigitated electrodes serves to increase the capacitor area surface while maintaining a minimal horizontal foot print. Since capacitance is proportional to the surface area the structure enables continual use of current dielectric materials such as Si3N4 at current thicknesses. In a second embodiment of the interdigitated MIMCAP structure the electrodes are formed in a spiral fashion which serves to increase the physical strength of the MIMCAP. Also included is a spiral shaped capacitor electrode which lends itself to modular design by offering a wide range of discrete capacitive values easily specified by the circuit designer.

  • Publication number: 20050199966
    Abstract: A dual work function semiconductor structure with borderless contact and method of fabricating the same are presented. The structure may include a field effect transistor (FET) having a substantially cap-free gate and a conductive contact to a diffusion adjacent to the cap-free gate, wherein the conductive contact is borderless to the gate. Because the structure is a dual work function structure, the conductive contact is allowed to extend over the cap-free gate without being electrically connected thereto.
