Publication number: 20090293273Abstract: A method for forming a self-aligned nanotube contact structure by selectively depositing metal over nanotubes or through a nanotube network onto an interconnect layer formed below is provided. An interconnect layer is formed over a first layer of a microelectronics device. A second layer of the microelectronics device is then formed over the interconnect layer and vias are patterned through the second layer. The vias are filled with metal and a nanotube layer is formed over the vias such that openings remain in the nanotube layer. Self-aligned electrodes are formed in the openings by selective electroless plating or chemical vapor deposition such that the electrodes substantially fill only the openings in the nanotube layer that substantially reside over the metal in the vias. The resulting self-aligned nanotube contact structure envelops individual nanotubes in the region and provides low contact resistance.Type: ApplicationFiled: February 11, 2009Publication date: December 3, 2009Applicant: HONEYWELL INTERNATIONAL INC.Inventor: Thomas Keyser

Patent number: 7454102Abstract: An optoelectronic coupling structure, a method of manufacture, and a method of operation are described. The optical coupling structure includes a waveguide that is formed within a device layer of an SOI substrate. A prism is located on a bottom side of the SOI substrate. A BOX layer of the SOI substrate, which is interposed between the prism and the waveguide, serves as a spacer region, which promotes an optical coupling of the prism to the waveguide. By positioning the prism below the waveguide, an optoelectronic IC may more readily accommodate a prism. The prism may be directly fabricated in a bulk layer of the SOI substrate or directly bonded to a bottom side surface of the BOX layer.Type: GrantFiled: April 26, 2006Date of Patent: November 18, 2008Assignee: Honeywell International Inc.Inventors: Thomas Keyser, Grenville Hughes

Publication number: 20070274655Abstract: A method of fabrication and a structure for a low-loss optical device. The optical device structure includes a waveguide that is formed within a device layer of an SOI substrate. A cladding region is formed beneath the waveguide and a BOX layer of the SOI substrate. The cladding region may comprise an air cavity or a cavity that is filled or at least partially filled with a dielectric material. Because the cladding region is formed in the bottom side, it supplements the BOX layer cladding. Consequently, a thinner BOX layer may be used for both electronic and optical devices, which facilitates optoelectronic IC processing and design.Type: ApplicationFiled: November 7, 2006Publication date: November 29, 2007Applicant: HONEYWELL INTERNATIONAL INC.Inventors: Thomas Keyser, Grenville Hughes, Jerry Yue
