Patents by Inventor King Tsu-Jae

King Tsu-Jae has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6956262
    Abstract: A charge trapping semiconductor device is particularly suited as a replacement for conventional pull-up and load elements such as NDR diodes, passive resistors, and conventional FETs. The device includes a charge trapping layer formed at or extremely near to an interface between a substrate (which can be silicon or SOI) and a gate insulation layer. The charge trapping device can be shut off during static operations to further reduce power dissipation.
    Type: Grant

    Date of Patent: October 18, 2005
    Assignee: Synopsys Inc.

  • Patent number: 6894327
    Abstract: A negative differential resistance device is disclosed which is particularly suited as a replacement for conventional pull-up and load elements such as NDR diodes, passive resistors, and conventional FETs. The NDR device includes a charge trapping layer formed at or extremely near to an interface between a substrate (which can be silicon or SOI) and a gate insulation layer. The NDR device can be shut off during static operations to further reduce power dissipation.

  • Patent number: 6724024
    Abstract: An improved MISFET is disclosed which is particularly suited as a replacement for conventional pull-up and load elements such as NDR diodes, passive resistors, and conventional FETs. The MISFET includes a charge trapping layer formed at or extremely near to an interface between a substrate (which can be silicon or SOI) and a gate insulation layer. In this fashion, charge traps can be optimized for extremely rapid trapping and de-trapping of charge because they are extremely close to a channel of hot carriers. The MISFET channel can be shut off during static operations to further reduce power dissipation, and can also be adapted to operate with negative differential resistance.

  • Patent number: 6594193
    Abstract: An integrated circuit device includes a charge pump for providing a bias signal to a field effect transistor (FET) that is capable of operating in a negative differential resistance mode. The bias signal is applied to a gate of the NDR FET to control the characteristics of the NDR behavior.

  • Patent number: 6559470
    Abstract: An improved negative differential resistance field effect transistor (NDR-FET) is disclosed. The NDR FET includes a charge trapping layer formed at or extremely near to an interface between a substrate (which can be silicon or SOI) and a gate insulation layer. In this fashion, charge traps can be optimized for extremely rapid trapping and de-trapping of charge because they are extremely close to a channel of hot carriers. The NDR-FET is also useable as a replacement for conventional NDR diode and similar devices in memory cells, and enables an entire family of logic circuits that only require a single channel technology (i.e., instead of CMOS) and yet which provide low power.
