  • Patent number: 8289748
    Abstract: Method and apparatus for tuning a variable resistance resistive sense element of an electronic device. In some embodiments, a value indicative of a selected number of consecutive pulses is stored in a memory location and a resistive sense element (RSE) is set to a baseline RSE resistance. A tuning operation is performed by applying the selected number of consecutive pulses to the RSE to tune the baseline RSE resistance to a final adjusted resistance.

  • Patent number: 7402364
    Abstract: An alternating phase shift mask with dark loops thereon, a memory array fabricated with the alternating phase shift mask, and a method of fabricating the memory. The dark loops in the mask always separate first regions with 180° phase difference from second regions with 0° phase difference to define active areas or gate-lines in a DRAM chip. By using the alternating phase shift mask to pattern gate-lines or active areas in a DRAM array, no unwanted image is created in the DRAM array and only one exposure is needed to achieve high resolution requirement.

  • Patent number: 7329916
    Abstract: The invention is related to a DRAM cell arrangement with vertical MOS transistors. Channel regions arranged along one of the columns of a memory cell matrix are parts of a rib which is surrounded by a gate dielectric layer. Gate electrodes of the MOS transistors belonging to one row are parts of a strip-like word line, so that at each crossing point of the memory cell matrix there is a vertical dual-gate MOS transistor with gate electrodes of the associated word line formed in the trenches on both sides of the associated rib.

  • Patent number: 6828615
    Abstract: A dynamic random access memory (DRAM) device having a vertical transistor and an internally-connected strap (ICS) to connect the transistor to the capacitor. The ICS makes no direct contact with the substrate. The DRAM cell operates at a substantially lower cell capacitance than that required for a conventional buried strap trench (BEST) cell without causing any negative impact on device performance. The lower cell capacitance also extends the feasibility of deep trench capacitor manufacturing technology without requiring new materials or processing methods. A method of manufacturing the DRAM includes forming a very thin Si layer on top of a DT cell while at the same time the method forms an isolated layer replacing a conventional collar. The formation of the SOI by internal thermal oxidation (ITO) makes the structure in such a manner that the device may be fully depleted.

  • Patent number: 6770954
    Abstract: The present invention provides a semiconductor device in which a low resistance, tunable contact is formed by means of using a SixGe1−x (0<x<1) layer. Thus, only moderate doping is required, which in turn protects the device from short channel effect and leakage. The low resistance, tunable contact is suitable for CMOS devices.

  • Patent number: 6703279
    Abstract: The present invention provides a metal contact of SiGe combined with cobalt silicide and cobalt. The contact resistance is greatly lowered due to both the low Schottky Barrier Height of SiGe and the low sheet resistance of cobalt silicide. The cobalt layer can serve as a glue layer and diffusion barrier layer. Thus, no additional glue layer or diffusion barrier layer needs to be formed. Moreover, the metal contact of the present invention can be integrated with a DRAM by a hybrid contact method. Implantation contact is used in pFET regions and diffusion contact is used in nFET regions. This can reduce mask steps and production costs.

  • Publication number: 20030131927
    Abstract: The present invention is directed to a method and system for transferring a molded element onto a textile material comprising the steps of: (a) heating a liquid polymeric material inside a mold to transform the liquid polymeric material from a liquid to a gel to form a molded element; (b) applying the molded element in the mold to the textile material with heat and pressure in order to transfer the molded element from the mold onto the textile material; and, (c) cooling the molded element on the textile material by applying cold and pressure to the molded element in the mold in order to adhere the molded element to the textile material.

  • Patent number: 6544888
    Abstract: An advanced contact integration technique for deep-sub-150 nm semiconductor devices such as W/WN gate electrodes, dual work function gates, dual gate MOSFETs and SOI devices. This technique integrates self-aligned raised source/drain contact processes with a process employing a W-Salicide combined with ion mixing implantation. The contact integration technique realizes junctions having low contact resistance (RC), with ultra-shallow contact junction depth (XJC) and high doping concentration in the silicide contact interface (Nc).
