Patents by Inventor Alok Nandini ROY

Alok Nandini ROY 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).

  • Publication number: 20200075088
    Abstract: Integrated circuits with an array of programmable resistive switch elements are provided. A programmable resistive switch element may include two non-volatile resistive memory elements connected in series and two varistors. A first of the two varistors is used to program a top resistive memory element in the resistive switch element, whereas a second of the two varistors is used to program a bottom resistive memory element in the resistive switch element. Row and column drivers implemented using only thin gate oxide transistors are used to program a selected resistive switch in the array without violating a maximum voltage level that satisfies predetermined defects per million (DPM) reliability criteria.
    Type: Application

  • Patent number: 9111985
    Abstract: A shallow bipolar junction transistor comprising a high voltage n+ well implanted into a semiconductor substrate. The shallow bipolar junction transistor further comprises a bit line n+ implant (BNI) above the high voltage n+ well and an oxide nitride (ONO) layer above the high voltage n+ well. A portion of the ONO layer isolates the BNI from a shallow trench isolation (STI) region.

  • Patent number: 9041203
    Abstract: A system and method for manufacturing a semiconductor device including multi-layer bitlines. The location of the bitlines in multiple layers provides for increased spacing and increased width thereby overcoming the limitations of the pitch dictated by the semiconductor fabrication process used. The bitlines locations in multiple layers thus allows the customization of the spacing and width according to the use of a semiconductor device.

  • Publication number: 20100078814
    Abstract: A system and method for manufacturing a semiconductor device including a low dielectric constant porous material layer. Ions are implanted into the low dielectric constant porous material layer which thereby provides the porous material layer with sufficient mechanical strength for withstanding semiconductor manufacturing processes. The ions implanted in the porous material layer further facilitate disposition of a conductive layer on the porous material layer.
