  • Publication number: 20070069287
    Abstract: A p-type base layer shaped like a well is formed for each of IGBT cells, and a p+-type collector layer and an n+-type cathode layer are formed on a surface opposite to a surface on which the p-type base layer is formed so as to be situated just below the p-type base layer. The p-type base layer of each of the IGBT cells includes a flat region including an emitter region and a bottom surface penetrated by a main trench, and first and second side diffusion regions between which the flat region is interposed. The first side diffusion region is situated just above the n+-type cathode layer and each of the bottom surfaces of the side diffusion regions forms a parabola-shaped smooth curve in longitudinal section. By replacing the p+-type collector layer with the n+-type cathode layer, it is possible to apply features of the above structure to a power MOSFET.

  • Publication number: 20070069288
    Abstract: A semiconductor device for preventing a parasitic bipolar transistor from operating while reducing the ON resistance of a double-diffused MOS transistor. Boron having a relatively high solid solubility limit in silicon and indium having a relatively low solid solubility limit in silicon are diffused as p-type impurities into a body region. The concentration ratio of indium with respect to boron is higher in the vicinity of a source diffusion layer in the body region than in other portions. Thus, indium that does not solidify remains in the lattice of silicon. This reduces the lifetime of carriers in the body region and prevents the parasitic bipolar transistor from operating. The lateral junction abruptness at a pn junction between the body region and the source diffusion layer is improved, and the ON resistance of the DMOS transistor is reduced.

  • Publication number: 20070069296
    Abstract: A cell design and methods for reducing the cell size of cells in high-current devices, such as MRAM, by increasing the effective width of a transistor in the cell to be greater than the actual width of the active area of the cell are described. This permits the cell size to be decreased without decreasing the current that is driven by the transistor. According to the invention, this is achieved by increasing the length of gate portions of one or more transistors within the active area of a cell to increase the effective transistor width. In one embodiment, two transistors, electrically connected in parallel, are used per cell. The two transistors double the effective transistor width within the cell relative to a single transistor design. Such cell designs can be used with a variety of devices, including various types of MRAM and PCRAM.

  • Publication number: 20070069306
    Abstract: An apparatus and method of manufacture for metal-oxide semiconductor (MOS) transistors is disclosed. Devices in accordance with the invention are operable at voltages below 2V. The devices are area efficient, have improved drive strength, and have reduced leakage current. A dynamic threshold voltage control scheme comprised of a forward biased diode in parallel with a capacitor is used, implemented without changing the existing MOS technology process. This scheme controls the threshold voltage of each transistor. In the OFF state, the magnitude of the threshold voltage of the transistor increases, keeping the transistor leakage to a minimum. In the ON state, the magnitude of the threshold voltage decreases, resulting in increased drive strength. The invention is particularly useful in MOS technology for both bulk and silicon on insulator (SOI) CMOS. The use of reverse biasing of the well, in conjunction with the above construct to further decrease leakage in a MOS transistor, is also shown.

    Abstract: Mounting components such as LSIs, which emit noise to the outside and are subjected to the influence of external noise, on the top-most layer and the bottom-most layer respectively, a co-existing layer of the ground region and the power source region has been employed, where a ground region has been provided respectively to the range corresponding to the position the LSIs on the next layer below the top-most layer and the next layer above the bottom-most layer. Accordingly, the number of layers to be laminated to form the multilayer substrate has been reduced, because it is no longer required, unlike the related art, to provide a ground layer where the ground pattern is formed substantially over the entire surface of layer respectively to the next layer below the top-most layer having mounted a LSI thereon and of the next layer above the bottom-most layer having mounting a LSI thereon.

  • Publication number: 20070069326
    Abstract: A semiconductor device which, in spite of the existence of a dummy active region, eliminates the need for a larger chip area and improves the surface flatness of the semiconductor substrate. In the process of manufacturing it, a thick gate insulating film for a high voltage MISFET is formed over an n-type buried layer as an active region and a resistance element IR of an internal circuit is formed over the gate insulating film. Since the thick gate insulating film lies between the n-type buried layer and the resistance element IR, the coupling capacitance produced between the substrate (n-type buried layer) and the resistance element IR is reduced.

    Abstract: In a method for manufacturing an integrated semiconductor device with low capacitive coupling between a conductive member and a via, a semiconductor substrate with a surface is provided. The conductive member is formed on the surface of the substrate wherein the conductive member is provided for conducting a current in a direction parallel to the surface of the substrate. A sacrifice structure is produced. A via is formed for conducting a current in a direction vertical to the surface of the substrate. The sacrifice structure at least partially defines the shape and position of the via and separates the conductive member and the via. The sacrifice structure is removed thereby generating a void in place of the sacrifice structure.
