  • Patent number: 7232748
    Abstract: A BARC or other sacrificial fill layer etch comprises a selective etch chemistry of Ar/O2/CO. The BARC etch may be used in a via-first dual damascene method. After via (116) pattern and etch, a BARC/sacrificial fill layer (120) is deposited to fill the via (116) and coat the IMD (110). The excess sacrificial fill layer (120) material over the IMD (110) is removed using the Ar/O2/CO etch. A trench resist pattern (125) is formed over the BARC layer (120). During the main trench etch, portions of sacrificial fill layer (120) remain in the via to protect the etch-stop (104) at the bottom of the via (116).

  • Patent number: 7233194
    Abstract: This invention is a new CMOS voltage booster (20) having an output which can be used in memories to boost the word line voltage above VDD or other voltage boosting applications. The CMOS booster includes a NMOS FET (MN1) to charge a boosting capacitor (C1) to VDD at the end of each memory access and includes a PMOS FET (MP1, MP2) to keep the voltage at the output at VDD during standby. By using this combination, the word line rise time, the size of the booster, and the power consumption during access are significantly reduced. The gate of the NMOS FET (MN1) is boosted above VDD+Vthn by a small capacitor (C2) to charge the word line boosting capacitor to VDD at the end of each memory access. The small capacitor (C2) is pre-charged to VDD by a NMOSFET (MN2) whose gate is connected to the word line boosting capacitor. The gate of each PMOS FET (MP1, MP2) is shorted to its source to turn if off during boostenig. Transistor (MP3) facilitates boosting the NMOS FET (MN1) above VDD.

  • Patent number: RE39697
    Abstract: A nonvolatile memory array is encased in a P-well, and the P-well encased in a deep N-well, the two wells separating the memory array from the integrated circuit substrate and from the other circuitry of the integrated circuit. At the same time the deep N-well is formed for the nonvolatile memory array, deep N-wells are formed for the high-voltage P-channel transistors of the logic circuitry. At the same time the P-well is formed for the nonvolatile memory array, P-wells are formed for the low-voltage N-channel transistors. The memory array contains nonvolatile cells of the type used in the ultra-violet-erasable EPROMs. During erasure, the isolated-well formation allows the source, the drain and the channel of selected cells to be driven to a positive voltage. The isolated well is also driven to a positive voltage equal to, or slightly greater than, the positive voltage applied to the source and drain, thus eliminating the field-plate breakdown-voltage problem.
