Patent number: 8129257Abstract: InP epitaxial material is directly bonded onto a Silicon-On-Insulator (SOI) wafer having Vertical Outgassing Channels (VOCs) between the bonding surface and the insulator (buried oxide, or BOX) layer. H2O and other molecules near the bonding surface migrate to the closest VOC and are quenched in the buried oxide (BOX) layer quickly by combining with bridging oxygen ions and forming pairs of stable nonbridging hydroxyl groups (Si—OH). Various sizes and spacings of channels are envisioned for various devices.Type: GrantFiled: January 14, 2009Date of Patent: March 6, 2012Assignee: The Regents of the University of CaliforniaInventor: Di Liang

Patent number: 8097492Abstract: A Silicon Based Package (SBP) is formed starting with a thick wafer, which serves as the base for the SBP, composed of silicon which has a first surface and a reverse surface which are planar. Then form an interconnection structure including metal capture structures in contact with the first surface and multilayer conductor patterns over the first surface. Form a temporary bond between the SBP and a wafer holder, with the wafer holder being a rigid structure. Thin the reverse side of the wafer to a desired thickness to form an Ultra Thin Silicon Wafer (UTSW) for the SBP. Form via holes with tapered or vertical sidewalls, which extend through the UTSW to reach the metal capture structures. Then form metal pads in the via holes which extend through the UTSW, making electrical contact to the metal capture structures. Then bond the metal pads in the via holes to pads of a carrier.Type: GrantFiled: December 24, 2008Date of Patent: January 17, 2012Assignee: International Business Machines CorporationInventors: John H.

Patent number: 8071398Abstract: The present invention relates to integrating an inertial mechanical device on top of an IC substrate monolithically using IC-foundry compatible processes. The IC substrate is completed first using standard IC processes. A thick silicon layer is added on top of the IC substrate. A subsequent patterning step defines a mechanical structure for inertial sensing. Finally, the mechanical device is encapsulated by a thick insulating layer at the wafer level. Compared with the incumbent bulk or surface micromachined MEMS inertial sensors, vertically monolithically integrated inertial sensors provided by embodiments of the present invention have one or more of the following advantages: smaller chip size, lower parasitics, higher sensitivity, lower power, and lower cost.Type: GrantFiled: December 9, 2009Date of Patent: December 6, 2011Assignee: MCube Inc.Inventor: Xiao (Charles) Yang
