    摘要: Disclosed is a low threshold asymmetric MOS device having a pocket region with a graded concentration profile. The pocket region includes a relatively high dopant atom concentration (of the same conductivity type as the bulk region) abutting either the device's source or its drain along the side of the source or drain that faces the device's channel region. The pocket region's graded concentration profile provides a lower dopant concentration near the substrate surface and an increasing dopant concentration below that surface. This provides a relatively low resistance conduction path through the pocket region, while allowing the device's threshold voltage to be somewhat higher at the pocket region. The asymmetric device can also include a counter dopant region located beneath its substrate surface. This forces current to flow in the substrate but just above the region of high counter dopant concentration, where the resistance is relatively low.

    摘要: Low threshold voltage MOS devices having asymmetric halo implants are disclosed herein. An asymmetric halo implant provides a pocket region located under a device's source or drain near where the source (or drain) edge abuts the device's channel region. The pocket region has the same conductivity type as the device's bulk (albeit at a higher dopant concentration) and, of course, the opposite conductivity type as the device's source and drain. Only the source or drain, not both, have the primary pocket region. An symmetric halo device behaves like two pseudo-MOS devices in series: a "source FET" and a "drain FET." If the pocket implant is located under the source, the source FET will have a higher threshold voltage and a much shorter effective channel length than the drain FET.

    摘要: A dynamic clocked inverter latch with reduced charge leakage includes a first node biasing circuit with a P-MOSFET and an N-MOSFET totem-pole-coupled between VDD and an output node, and a second node biasing circuit with another N-MOSFET and another P-MOSFET totem-pole-coupled between the output node and VSS. The first P-MOSFET receives an input data signal and the first N-MOSFET receives a clock signal and in accordance therewith together cause the output node to charge to a charged state having a charge voltage associated therewith. The second N-MOSFET also receives the input data signal while the second P-MOSFET receives the inverse of the clock signal and in accordance therewith together cause the output node to discharge to a discharged state having a discharge voltage associated therewith. During inactive states of the clock signal, the first N-MOSFET becomes reverse-biased by the output node discharge voltage, while during inactive states of the inverse clock signal, the second P-MOSFET becomes reverse-biased by the output node charge voltage, thereby virtually eliminating charge leakage to and from the output node, respectively.

    摘要: Systems and methods for adjusting threshold voltage. A threshold voltage of a transistor of an integrated circuit is measured. A bias voltage, which when applied to a body well of the transistor corrects a difference between the threshold voltage and a desired threshold voltage for the transistor, is determined. The bias voltage is encoded into non-volatile storage on the integrated circuit. The non-volatile storage can be digital and/or analog.

    摘要: A method for the design and layout for a patterned deep N-well. A tile is specified as a fundamental building block for the deep N-well pattern. The tile comprises a first element on a first layer and may comprise a second element on a second layer. A two dimensional region is covered with an array of contiguous tiles, with the elements on each layer connecting with elements of adjacent tiles to form extended shapes. The array may be converted to a collection of sub-arrays through the removal of tiles. The array or collection of sub-arrays may be merged to produce a first layer pattern and second layer pattern. Design rule checks may be applied to verify the pattern. The first layer shapes and second layer shapes may be edited. The first layer shapes and the second layer shapes may then be combined to produce a deep N-well pattern.
