    Type: Grant
    Filed: August 20, 2009
    Date of Patent: April 2, 2013
    Assignee: International Business Machines Corporation
    Inventors: Guy Moshe Cohen, Patricia May Mooney
  • Patent number: 8053328
    Abstract: A method for depositing fine particles from a suspension on selected regions of a substrate is disclosed. The particles are deposited on selected regions of a clean hydrophobic semiconductor surface that are surrounded by a wetting boundary which includes a mesa formed by etching through a silicon-on-insulator (SOI) film and an underlying buried oxide of an SOI substrate. The process is well suited for the growth of semiconductor nanowires that nucleates from fine particle used as a catalyst.

  • Patent number: 7534675
    Abstract: Techniques for the fabrication of field-effect transistors (FETs) having nanowire channels are provided. In one aspect, a method of fabricating a FET is provided comprising the following steps. A substrate is provided having a silicon-on-insulator (SOI) layer. At least one nanowire is deposited over the SOI layer. A sacrificial gate is formed over the SOI layer so as to cover a portion of the nanowire that forms a channel region. An epitaxial semiconductor material is selectively grown from the SOI layer that covers the nanowire and attaches the nanowire to the SOI layer in a source region and in a drain region. The sacrificial gate is removed. An oxide is formed that divides the SOI layer into at least two electrically isolated sections, one section included in the source region and the other section included in the drain region. A gate dielectric layer is formed over the channel region. A gate is formed over the channel region separated from the nanowire by the gate dielectric layer.

  • Patent number: 7496251
    Abstract: Apparatus and methods for packaging optical communication devices include optical bench structures, such as silicon-optical benches (SiOB). An optical communications apparatus includes an optical bench comprising a substrate having an electrical turning via formed therein. An optoelectronic (OE) chip and integrated circuit (IC) chip are mounted on the optical bench and electrically connected using the electrical turning via. The electrical turning via extends in directions both perpendicular and transverse to a surface of the substrate such that the OE chip and IC chip can be mounted on perpendicular surfaces of the optical bench in close proximity and electrically connected using the electrical turning via.

  • Publication number: 20090035919
    Abstract: A method for bonding microstructures to a semiconductor substrate using attractive forces, such as, hydrophobic, van der Waals, and covalent bonding is provided. The microstructures maintain their absolute position with respect to each other and translate vertically onto a wafer surface during the bonding process. The vertical translation of the micro-slabs is also referred to herein as “in-place bonding”. Semiconductor structures which include the attractively bonded microstructures and substrate are also disclosed.
