Narendra N. Singhdeo 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: 5024883
    Abstract: The present invention is directed to components and the process of forming the components for housing semiconductor devices. The components are formed of a unique ceramic-glass-metal composite material comprising ceramic particles, metallic particles and a glass matrix with said ceramic and metallic particles dispersed throughout. Metal elements can be embedded into the material to enable simplified fabrication of devices such as semiconductor packaging.
    Type: Grant
    Filed: September 14, 1989
    Date of Patent: June 18, 1991
    Assignee: Olin Corporation
    Inventors: Narendra N. SinghDeo, Deepak Mahulikar, Sheldon H. Butt
  • Patent number: 4929516
    Abstract: A semiconductor die attach system adapted for attaching a semiconductor die to a substrate is provided. A metallic buffer component for dissipating thermal stresses is disposed between the substrate and the semiconductor die to dissipate stresses created from thermal cycling of the substrate and the die. The metallic buffer component is sealed between the substrate and the die with a silver-tin sealing composition. A bonding material may be used alone to bond a die to a substrate and dissipate stresses from thermal cycling.

  • Patent number: 4821151
    Abstract: A hermetically sealed package adapted to house a plurality of semiconductor devices. The package include a multi-layer circuit device formed of a plurality of ceramic substrates and conductive circuit patterns disposed therebetween. A ceramic cover having at least one cavity adapted for receiving a semiconductor die is sealed to the multi-layer circuit device. Electrical leads are connected to the semiconductor device and extend outward from the package for connection to the conductive circuit pattern within the multi-layer circuit.

  • Patent number: 4756754
    Abstract: The present invention relates to a composite formed of a mixture of ceramic particles and at least two metallic components adhered together with a glassy phase. A first of the metallic components, in particle form, enhances the flow characteristics of the mixture where the second metallic component and the glass are in the molten condition. The final composite is a continuous phase of the second metallic component having particles of the first metallic component and glass coated ceramic particles distributed therein.

  • Patent number: 4687540
    Abstract: This invention relates to a laminated glass capacitor and method of making the capacitor. The capacitor is constructed of a plurality of internal electrodes stacked and having glass layers therebetween to give electrostatic capacity. External electrodes are connected to associated internal electrodes for taking out the electrostatic capacity. The glass layers are selected from a substantially pore free glass and the internal electrodes are formed of a metal foil selected from the group consisting of deoxidized copper alloy and oxygen free copper alloy.
