Patent number: 6838896Abstract: A single gas tight system may perform multi-functions including reducing the thickness of oxides on contact pads and probing, testing, burn-in, repairing, programming and binning of integrated circuits. A holding fixture holds a wafer having integrated circuits and aligns the wafer to a full-substrate probing device. A temperature control device is used to heat the wafer during an oxide reduction process or during burn-in of the wafer. During the oxide reduction process, hydrogen is introduced into the chamber, and the wafer is heated so that the oxides on the contact pads can combine with hydrogen to form water vapor, thus reducing the thickness of the oxides. A computer analyzes the test and/or burn-in data and provides control signals for repairing or programming the integrated circuits.Type: GrantFiled: September 6, 2001Date of Patent: January 4, 2005Assignee: Elm Technology CorporationInventor: Glenn Leedy

Publication number: 20040192045Abstract: General purpose methods for the fabrication of integrated circuits from flexible membranes formed of very thin low stress dielectric materials, such as silicon dioxide or silicon nitride, and semiconductor layers. Semiconductor devices are formed in a semiconductor layer of the membrane. The semiconductor membrane layer is initially formed from a substrate of standard thickness, and all but a thin surface layer of the substrate is then etched or polished away. In another version, the flexible membrane is used as support and electrical interconnect for conventional integrated circuit die bonded thereto, with the interconnect formed in multiple layers in the membrane. Multiple die can be connected to one such membrane, which is then packaged as a multi-chip module. Other applications are based on (circuit) membrane processing for bipolar and MOSFET transistor fabrication, low impedance conductor interconnecting fabrication, flat panel displays, maskless (direct write) lithography, and 3D IC fabrication.Type: ApplicationFiled: January 27, 2004Publication date: September 30, 2004Applicant: Elm Technology Corporation.Inventor: Glenn Joseph Leedy

Publication number: 20040151043Abstract: A Three-Dimensional Structure (3DS) Memory allows for physical separation of the memory circuits and the control logic circuit onto different layers such that each layer may be separately optimized. One control logic circuit suffices for several memory circuits, reducing cost. Fabrication of 3DS memory involves thinning of the memory circuit to less than 50 &mgr;m in thickness and bonding the circuit to a circuit stack while still in wafer substrate form. Fine-grain high density inter-layer vertical bus connections are used. The 3DS memory manufacturing method enables several performance and physical size efficiencies, and is implemented with established semiconductor processing techniques.Type: ApplicationFiled: December 18, 2003Publication date: August 5, 2004Applicant: Elm Technology CorporationInventor: Glenn J.

Patent number: 6564503Abstract: In an apparatus for trapping and killing insects using an electric discharge between electrodes to count and/or kill insects or the like, the present invention presents a technology to almost certainly count and/or kill the insects or the like even when the applied voltage is set low. In an insect-trapping/killing apparatus as an embodiment of the invention, when an insect or the like enters the space between an outer electrode and a central electrode, an electric discharge passes through the insect or the like, whereby the insects or the like is killed. After that, the central electrode is rotated in a preset direction to remove the insect or the like downwards by the frictional force. Since the removing mechanism as described above solves the problem of the clogging of the space between electrodes by the insect or the like, the distance between the electrodes can be set as small as the size of the body of the insect or the like, and the applied voltage can be set accordingly low.Type: GrantFiled: December 10, 2001Date of Patent: May 20, 2003Assignee: Elm, Inc.Inventors: Takakazu Miyahara, Shoichi Izumi, Hidemi Kamiwada, Kaoru Takemura
