Maurice Heathcote Norcott 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: 6334247
    Abstract: The present invention is directed to a high density test probe which provides a means for testing a high density and high performance integrated circuits in wafer form or as discrete chips. The test probe is formed from a dense array of elongated electrical conductors which are embedded in an compliant or high modulus elastomeric material. A standard packaging substrate, such as a ceramic integrated circuit chip packaging substrate is used to provide a space transformer. Wires are bonded to an array of contact pads on the surface of the space transformer. The space transformer formed from a multilayer integrated circuit chip packaging substrate. The wires are as dense as the contact location array. A mold is disposed surrounding the array of outwardly projecting wires. A liquid elastomer is disposed in the mold to fill the spaces between the wires.

  • Publication number: 20010054907
    Abstract: Probes for electronic devices are described. The probe is formed by ball bonding a plurality of wires to contact locations on a fan out substrate surface. The wires are cut off leaving stubs. A patterned polymer sheet having electrical conductor patterns therein is disposed over the stubs which extend through holes in the sheet. The ends of the wires are flattened to remit the polymer sheet in place. The wire is connected to an electrical conductor on the polymer sheet which is converted to a contact pad on the polymer sheet. A second wire is ball bonded to the pad on the polymer sheet and cut to leave a second stub. The polymer sheet is laser cut so that each second stub is free to move independently of the other second studs. The ends of the second stubs are disposed against contact locations of an electronic device, such as an FC chip, to test the electronic device.

  • Patent number: 6062879
    Abstract: The present invention is a structure for probing an electronic device. The structure has a layer of elastomeric material having a first side and a second side; a plurality of electrical conductors extending from the first side to the second side; each of the electrical conductors has a first end and a second end, the first end extends to the first side, the second end extends to said second side; a layer of dielectric material disposed on the first side; the first end of the plurality of electrical conductors extends into openings in the layer of dielectric material. More particularly, in the present invention, the second side is disposed in contact with a first surface of a substrate and the second ends of the electrical conductors are electrically connected to first electrical contact locations on the first surface.
