Patent application numberDescriptionPublished
20080251880MIXED ORIENTATION AND MIXED MATERIAL SEMICONDUCTOR-ON-INSULATOR WAFER - The present disclosure relates, generally, to a semiconductor substrate with a planarized surface comprising mixed single-crystal orientation regions and/or mixed single-crystal semiconductor material regions, where each region is electrically isolated. In accordance with one embodiment of the disclosure CMOS devices on SOI regions are manufactured on semiconductors having different orientations. According to another embodiment, an SOI device is contemplated as having a plurality of semiconductor regions having at least one of a different semiconductor material, crystalline lattice constant or lattice strain. Methods and processes for fabricating the different embodiments of the invention is also disclosed.10-16-2008
20090117694NANOWIRE BASED NON-VOLATILE FLOATING-GATE MEMORY - A non-volatile memory transistor with a nanocrystal-containing floating gate formed by nanowires is disclosed. The nanocrystals are formed by the growth of short nanowires over a crystalline program oxide. As a result, the nanocrystals are single-crystals of uniform size and single-crystal orientation.05-07-2009
20090289320FAST P-I-N PHOTODETECTOR WITH HIGH RESPONSITIVITY - A lateral p-i-n photodetector is provided that includes an array of vertical semiconductor nanowires of a first conductivity type that are grown over a semiconductor substrate also of the first conductivity type. Each vertically grown semiconductor nanowires of the first conductivity type is surrounded by a thick epitaxial intrinsic semiconductor film. The gap between the now formed vertically grown semiconductor nanowires-intrinsic semiconductor film columns (comprised of the semiconductor nanowire core surrounded by intrinsic semiconductor film) is then filled by forming an epitaxial semiconductor material of a second conductivity type which is different from the first conductivity type. In a preferred embodiment, the vertically grown semiconductor nanowires of the first conductivity type are n+ silicon nanowires, the intrinsic epitaxial semiconductor layer is comprised of intrinsic epitaxial silicon, and the epitaxial semiconductor material of the second conductivity type is comprised of p+ silicon.11-26-2009
20090293162MONOLITHIC HIGH ASPECT RATIO NANO-SIZE SCANNING PROBE MICROSCOPE (SPM) TIP FORMED BY NANOWIRE GROWTH - A scanning probe where the micromachined pyramid tip is extended by the growth of an epitaxial nanowire from the top portion of the tip is disclosed. A metallic particle, such as gold, may terminate the nanowire to realize an apertureless near-field optical microscope probe.11-26-2009

20090311835NANOWIRE MOSFET WITH DOPED EPITAXIAL CONTACTS FOR SOURCE AND DRAIN - A FET structure with a nanowire forming the FET channel, and doped source and drain regions formed by radial epitaxy from the nanowire body is disclosed. A top gated and a bottom gated nanowire FET structures are discussed. The source and drain fabrication can use either selective or non-selective epitaxy.12-17-2009
20100047984SELF-ALIGNED METAL-SEMICONDUCTOR ALLOY AND METALLIZATION FOR SUB-LITHOGRAPHIC SOURCE AND DRAIN CONTACTS - A lateral double-gate FET structure with sub-lithographic source and drain regions is disclosed. The sub-lithographic source and drain regions are defined by a sacrificial spacer. Self-aligned metal-semiconductor alloy and metal contacts are made to the sub-lithographic source and drain using conventional silicon processing.02-25-2010
20100289744RFID-BASED INPUT DEVICE - A device for use with a computer system includes: an array of antennas for transmitting and receiving radio frequency signals; a portable unit operating within radio frequency range of the array of antennas, wherein a location of the portable unit is estimated by the radio frequency signals transmitted from the portable unit to a processor device. The device also includes storage for storing user identification.11-18-2010
20110133280DIFFERENT THICKNESS OXIDE SILICON NANOWIRE FIELD EFFECT TRANSISTORS - A method (that produces a structure) patterns at least two wires of semiconductor material such that a first wire of the wires has a larger perimeter than a second wire of the wires. The method performs an oxidation process simultaneously on the wires to form a first gate oxide on the first wire and a second gate oxide on the second wire. The first gate oxide is thicker than the second gate oxide. The method also forms gate conductors over the first gate oxide and the second gate oxide, forms sidewall spacers on the gate conductors, and dopes portions of the first wire and the second wire not covered by the sidewall spacers and the gate conductors to form source and drain regions within the first wire and the second wire.06-09-2011
