James J. Toomey 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: 8362531
    Abstract: Method of patterning a semiconductor structure is disclosed. The method involves crystallographic etching techniques to enhance a patterned monocrystalline layer as a hard mask. In one embodiment, the method includes bonding a monocrystalline silicon layer to a non-crystalline protective layer; patterning the monocrystalline layer to form a hard mask; enhancing the pattern of the hard mask; stripping the hard mask after conventional etching of protective layer; and forming a gate oxide thereon. The enhanced patterning of the hard mask is performed with crystallographic etching to replace optical effects of rounding and dimension narrowing at the ends of a defined region with straight edges and sharp corners. A resulting structure from the use of the enhanced patterned hard mask includes a layer of composite materials on the substrate of the semiconductor structure. The layer of composite materials includes different materials in discrete blocks defined by straight edges within the layer.

  • Patent number: 8178931
    Abstract: A method and apparatus for forming connections within a semiconductor device is disclosed. The semiconductor device incorporates a contact bridge between transistor contacts in close proximity. The contact bridge comprises a plurality of metal pillars each having a lower end in electrical contact with first and second transistor elements, respectively; one or more intermediate metal pillars disposed between and in electrical contact with an upper end of the metal pillars; and one or more separation regions of dielectric disposed below the intermediate metal pillar and between the lower ends of the first and second metal pillars.

  • Patent number: 7736966
    Abstract: The present invention relates to a method of fabricating a semiconductor substrate that includes forming at least first and second device regions, wherein the first device region includes a first recess having interior surfaces oriented along a first set of equivalent crystal planes, and wherein the second device region includes a second recess having interior surfaces oriented along a second, different set of equivalent crystal planes. The semiconductor device structure formed using such a semiconductor substrate includes at least one n-channel field effect transistor (n-FET) formed at the first device region having a channel that extends along the interior surfaces of the first recess, and at least one p-channel field effect transistor (p-FET) formed at the second device region having a channel that extends along the interior surfaces of the second recess.

  • Patent number: 7718993
    Abstract: A method for producing predetermined shapes in a crystalline Si-containing material that have substantially uniform straight sides or edges and well-defined inside and outside corners is provided together with the structure that is formed utilizing the method of the present invention. The inventive method utilizes conventional photolithography and etching to transfer a pattern, i.e., shape, to a crystalline Si-containing material. Since conventional processing is used, the patterns have the inherent limitations of rounded corners. A selective etching process utilizing a solution of diluted ammonium hydroxide is used to eliminate the rounded corners providing a final shape that has substantially straight sides or edges and substantially rounded corners.
