  • Patent number: 7233012
    Abstract: A flexible radiation source. The flexible radiation source has a layer of flexible material with at least one radionuclide dispersed therein to form a flexible, radioactive matrix. A layer of flexible nonradioactive material is also provided to which the flexible, radioactive matrix is permanently attached. The flexible radiation source can be folded or rolled from an extended or planar configuration to a folded or rolled configuration without causing the at least one radionuclide from becoming separated therefrom. The flexible matrix material is free from encapsulation by any rigid structure when in use. A storage and shielding container with a compact form factor is provided. The form factor of the storage and shielding container accommodates the flexible radiation source when the flexible radiation source is in its rolled or folded configuration, but does not accommodate the flexible radiation source when it is in fully extended or planar configuration.

  • Patent number: 7233018
    Abstract: Provided are high voltage metal oxide semiconductor field effect transistor (HVMOSFET) having a Si/SiGe heterojunction structure and method of manufacturing the same. In this method, a substrate on which a Si layer, a relaxed SiGe epitaxial layer, a SiGe epitaxial layer, and a Si epitaxial layer are stacked or a substrate on which a Si layer having a well region, a SiGe epitaxial layer, and a Si epitaxial layer are stacked is formed. For the device having the heterojunction structure, the number of conduction carriers through a potential well and the mobility of the carriers increase to reduce an on resistance, thus increasing saturation current. Also, an intensity of vertical electric field decreases so that a breakdown voltage can be maintained at a very high level. Further, a reduction in vertical electric field due to the heterojunction structure leads to a gain in transconductance (Gm), with the results that a hot electron effect is inhibited and the reliability of the device is enhanced.

  • Patent number: 7233043
    Abstract: A trench-gated MOSFET includes adjacent mesas formed on opposite sides of a trench. A body region in the first mesa extends downward below the level of the trenches and laterally across the bottom of the trenches. The body region in the second mesa extends part of the way down the mesa, leaving a portion of the drain abutting the trench. The body region in the second mesa includes a channel region adjacent a wall of the trench. The area where the drain abuts the trench is thus relatively restricted and the drain-gate capacitance of the device is reduced. Moreover, the drain-gate capacitance is made independent of the depth and width of the trenches, allowing greater freedom in the design of the MOSFET.

  • Patent number: 7233047
    Abstract: An improved surface P-channel transistor includes providing a semiconductor substrate, forming a gate oxide layer over the semiconductor substrate, subjecting the gate oxide layer to a remote plasma nitrogen hardening treatment followed by an oxidative anneal, and forming a polysilicon layer over the resulting gate oxide layer. Significantly, the present invention does not require nitrogen implantation through the polysilicon layer overlying the gate oxide and provides a surface P-channel transistor having a polysilicon electrode free of nitrogen and a hardened gate oxide layer characterized by a large concentration of nitrogen at the polysilicon electrode/gate oxide interface and a small concentration of nitrogen at the gate oxide/semiconductor substrate interface.

  • Patent number: 7233048
    Abstract: A method for forming through hole vias in a substrate uses a partially exposed seed layer to plate the bottom of a blind trench formed in the front side of a substrate. Thereafter, the plating proceeds substantially uniformly from the bottom of the blind hole to the top. To form the through hole, the rear face of the substrate is ground or etched away to remove material up to and including the dead-end wall of the blind hole.

  • Patent number: 7233053
    Abstract: To fabricate an integrated semiconductor product with integrated metal-insulator-metal capacitor, first of all a dielectric auxiliary layer (6) is deposited on a first electrode (2, 3, 5). This auxiliary layer (6) is then opened up (15) via the first electrode. Then, a dielectric layer (7) is produced, and the metal track stack (8, 9, 10) for the second electrode is then applied to the dielectric layer (6). This is followed by the patterning of the metal-insulator-metal capacitor using known etching processes. This makes it possible to produce dielectric capacitor layers of any desired thickness using materials which can be selected as desired. In particular, this has the advantage that via etches can be carried out significantly more easily than in the prior art, since it is not necessary to etch through the residual dielectric capacitor layer above the metal tracks.
