  • Publication number: 20110241092
    Abstract: Transistors (21, 41) employing floating buried layers (BL) (72) may exhibit transient breakdown voltage (BVdss)TR significantly less than (BVdss)DC. It is found that this occurs because the floating BL (72) fails to rapidly follow the applied transient, causing the local electric field within the device to temporarily exceed avalanche conditions. (BVdss)TR of such transistors (69. 69?) can be improved to equal or exceed (BVdss)DC by including a charge pump capacitance (94, 94?) coupling the floating BL (72) to whichever high-side terminal (28, 47) receives the transient. The charge pump capacitance (94, 94?) may be external to the transistor (69, 69?), may be formed on the device surface (71) or, may be formed internally to the transistor (69-3, 69?-3) using a dielectric deep trench isolation wall (100) separating DC isolated sinker regions (86, 88) extending to the BL (72). The improvement is particularly useful for LDMOS devices.

Information from sensors is applied to a control unit to control the movement of the movable substrate. Coulomb islands are formed in the juxtaposed edges of a first substrate and second substrate, respectively. The islands generate edge Coulomb forces. These edge Coulomb forces can be used to detach, repel, move, attract and reattach the edges of substrates into new configurations.

    Abstract: A source-drain voltage of one of two transistors connected in series becomes quite small in a set operation (write signal), thus the set operation is performed to the other transistor. In an output operation, two transistors operate as a multi-gate transistor, therefore, a current value can be small in the output operation. In other words, a current can be large in the set operation. Therefore, the set operation can be performed rapidly without being easily influenced by an intersection capacitance and a wiring resistance which are parasitic on a wiring and the like. Further, an influence of variations between adjacent ones can be small as one same transistor is used in the set operation and the output operation.

This transistor includes a source or drain first region and a drain or source second region which are connected by a channel. A gate structure is position on top of said channel and operates to control the channel. The gate structure is formed in a trench whose sidewalls have a shape which converges (narrows) in the width dimension towards the substrate. A capacitor is also formed having a first electrode, a second electrode and a dielectric layer between the electrodes. This capacitor is also formed in a trench. An electrode line is connected to the first electrode of the capacitor. The second electrode of the capacitor is formed in a layer shared in common with at least part of the drain or source second region of the transistor.

  • Publication number: 20110186933
    Abstract: An integrated circuit includes a Schottky diode having a cathode defined by an n-type semiconductor region, an anode defined by a cobalt silicide region, and a p-type region laterally annularly encircling the cobalt silicide region. The resulting p-n junction forms a depletion region under the Schottky junction that reduces leakage current through the Schottky diodes in reverse bias operation. An n+-type contact region is laterally separated by the p-type region from the first silicide region and a second cobalt silicide region is formed in the n-type contact region. The silicided regions are defined by openings in a silicon blocking dielectric layer. Dielectric material is left over the p-type region. The p-type region may be formed simultaneously with source/drain regions of a PMOS transistor.

  • Publication number: 20110156162
    Abstract: In sophisticated semiconductor devices comprising high-k metal gate electrode structures formed on the basis of a replacement gate approach, semiconductor-based resistors may be provided without contributing to undue process complexity in that the resistor region is recessed prior to depositing the semiconductor material of the gate electrode structure. Due to the difference in height level, a reliable protective dielectric material layer is preserved above the resistor structure upon exposing the semiconductor material of the gate electrode structure and removing the same on the basis of selective etch recipes. Consequently, well-established semiconductor materials, such as polysilicon, may be used for the resistive structures in complex semiconductor devices, substantially without affecting the overall process sequence for forming the sophisticated replacement gate electrode structures.
