    摘要： A method for determining a reliable gate oxide thickness for a transistor involves subjecting test transistors to an alternating current (AC) voltage until the test transistors break down. The breakdown times of the test transistors are measured and correlated with the corresponding gate oxide thickness of the test transistor to form a reliability model of the transistor. The reliable gate oxide thickness is determined by extrapolating the reliability model out to a predetermined period of time for which reliability is desired, for example, ten years.

    摘要： A method and system for providing at least one contact in a flash memory device is disclosed. The flash memory device includes a plurality of gate stacks and at lease one component including a polysilicon layer as a top surface. The method and system further include forming a silicide on the top surface of the polysilicon layer and providing an insulating layer covering the plurality of gate stacks, the at least one component and the silicide. The method and system also include etching the insulating layer to provide at least one contact hole. The insulating layer etching step uses the silicide as an etch stop layer to ensure that the insulating etching step does not etch through the polysilicon layer. The method and system also include filling the at least one contact hole with a conductor.

    摘要： A NAND flash memory device incorporates a unique booster plate design. The booster plate is biased during read and program operations and the coupling to the floating gates in many cases reduces the voltage levels necessary to program and read the charge stored in the gates. The booster plate also shields against unwanted coupling between floating gates. Self boosting, local self boosting, and erase area self boosting modes used with the unique booster plate further improve read/write reliability and accuracy. A more compact and reliable memory device can hence be realized according to the present invention.

    摘要： A recording system stores recording cycle information identifying the parameters for recording user data on a particular data sector. During a subsequent operation, the recording system employs the recording cycle information to select a different set of parameters for recording new user data at the particular data sector. One of the parameters might identify a recorded pattern in a balance pad at the data sector, and another one of the parameters might identify a scrambler seed value. By employing a different set of recording parameters for each occurrence of recording user data at the particular sector, sample timing of, for example, a read channel might be based on an average of easy and hard transitions.

    摘要： A method of forming poly insulator poly capacitors by using self-aligned salicide process for mixed mode analog devices. These capacitors are formed in the self-aligned salicide process as stacked poly insulator poly (PIP) capacitors. In the self-aligned salicide process, a self-aligned salicide block process is needed to protect the the salicide formation process from electrostatic discharge (ESD) devices such as resistors or capacitors. The oxide layer of the self-aligned salicide block is used as the dielectric layer of the capacitors to form the PIP capacitor. Therefore, some process steps are omitted due to the formation of the PIP capacitors.

    摘要： An impedance matched write circuit is provided that shunts one or more matching resistors. The impedance matched write circuit includes an interconnect for connecting to a write head and at least one resistor between a control voltage and the interconnect for impedance matching to the interconnect. A transistor can be connected across the resistor to shunt current that would otherwise pass through the resistor during an overshoot mode. The transistor may be a PMOS transistor or a combination of PMOS and NMOS transistors. A gate voltage of the transistor is controlled by a source such that the transistor is turned on in an overshoot mode and turned off during a steady state mode.

    摘要： A semiconductor device having reduced field oxide recess and method of fabrication is disclosed. The method of fabricating the semiconductor device begins by performing an HF dip process on a substrate after field oxidation followed by performing a select gate oxidation. Thereafter, a core implant and a field implant are performed. After the implants, a tunnel oxide mask is deposited. The select gate oxide is then etched in areas uncovered by the tunnel oxide mask, and tunnel oxidation is performed.
