  • Patent number: 10276648
    Abstract: A method of fabricating ICs including thin film resistors (TFRs) depositing a dielectric liner layer on a substrate including a semiconductor surface having a plurality of IC die formed therein each including functional circuitry comprising a plurality of interconnected transistors. A TFR layer comprising chromium (Cr) is deposited on the dielectric liner layer. The TFR layer is plasma treated with atomic nitrogen and atomic hydrogen. A dielectric capping layer is deposited on the TFR layer after the plasma treating. A pattern is formed on the capping layer, and the TFR layer is etched to form at least one resistor that comprises the TFR layer.

  • Patent number: 10241140
    Abstract: The present disclosure provides systems and methods for monitoring power consumption of individual devices on an electric power system. A monitoring system may identify unique power characteristics of each device. The monitoring system may use the identified unique power characteristics to disaggregate electric data representative of the power consumption of all of the devices on the electric power system into portions associated with each device.

  • Patent number: 9064903
    Abstract: An analog floating-gate electrode in an integrated circuit, and method of fabricating the same, in which trapped charge can be stored for long durations. The analog floating-gate electrode is formed in a polycrystalline silicon gate level, doped n-type throughout its length, and includes portions serving as gate electrodes of n-channel and p-channel MOS transistors; a plate of a metal-to-poly storage capacitor; and a plate of poly-to-active tunneling capacitors. The p-channel MOS transistor includes a buried channel region, formed by way of ion implantation, disposed between its source and drain regions. Silicide-block silicon dioxide blocks the formation of silicide cladding on the electrode, while other polysilicon structures in the integrated circuit are silicide-clad.

  • Patent number: 8975135
    Abstract: An analog floating-gate electrode in an integrated circuit, and method of fabricating the same, in which trapped charge can be stored for long durations. The analog floating-gate electrode is formed in a polycrystalline silicon gate level, and includes portions serving as a transistor gate electrode, a plate of a metal-to-poly storage capacitor, and a plate of poly-to-active tunneling capacitors. A silicide-block film comprised of a layer of silicon dioxide underlying a top layer of silicon nitride blocks the formation of silicide cladding on the electrode, while other polysilicon structures in the integrated circuit, such as polysilicon-to-metal capacitors, are silicide-clad. Following silicidation, a capacitor dielectric is deposited over the remaining polysilicon structures, followed by formation of an upper metal plate.
