  • Publication number: 20070267673
    Abstract: One or more on-chip VNCAP or MIMCAP capacitors utilize a variable MOS capacitor to improve the uniform capacitance value of the capacitors. This permits the production of silicon semiconductor chips on which are mounted capacitors having capacitive values that are precisely adjusted to be within a range of between about 1% and 5% of their design value. This optimization can be achieved by the use of a back-to-back connection between a pair of the variable MOS capacitors for DC decoupling. It involves the parallelization of on-chip BEOL capacitance of VNCAP and/or MIMCAP capacitors by the insertion in the FEOL of pairs of back-to-back variable MOS capacitors.

These applications are of low-to-moderate performance requirements; hence ultra-low voltage subthreshold operation, where the supply voltage is less than the transistors threshold voltage, is suitable. By tying the PMOS body to the output node of the transistor circuit in which this PMOS is part of will provide the necessary body bias for this PMOS threshold voltage to change dynamically with the circuit's output status. The dynamic change of the PMOS transistor threshold voltage will consequently dynamically increase or decrease the subthreshold leakage current which is the switching current in subthreshold circuits.

  • Publication number: 20070267710
    Abstract: A photosensor includes a photovoltage generator for generating a photovoltage, and a comparator for determining a number of integer multiples of a threshold voltage associated with the photosensor. A primary counter is incremented by the determined number of integer multiples. A voltage injector adds at least one unit of voltage to the comparator, with each voltage unit having a value less than the threshold voltage. A secondary counter determines a number of voltage units needed to cause the voltage in the comparator to attain an integer multiple of the threshold voltage.

    Abstract: The present invention provides a structure and the manufacturing method of high precision chip capacitor fabricated on silicon substrate. The structure of the chip capacitor consists of a dielectric layer formed on the surface of a heavily doped silicon substrate with an inner primary portion of thin oxide and an outer secondary portion of thicker oxide; both oxides are merged seamlessly together into the single dielectric layer thus allowing a layer of electrically conducting film deposited on its surface as the first electrode of the capacitor, while the heavily doped silicon substrate on the opposite surface of the dielectric oxide plays as the bottom electrode. The bottom electrode is electrically connected up to a second electrode on the upper surface through a via so that both the first and second electrodes can be on the same surface for subsequent bumping process, finally, two solder bumps is formed on the top as a surface mountable chip capacitor component.
