  • Patent number: 7176545
    Abstract: 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.

  • Patent number: 7138295
    Abstract: 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 ?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.

  • Patent number: 6891387
    Abstract: A system which performs multi-functions including reducing the thickness of oxides on contact pads and probing, testing, burn-in, repairing, programming and binning of integrated circuits. The system includes: at least one module having a holding fixture, a wafer, a probing device, an electronic circuit board, and a temperature control device. There are a number of integrated circuits on the wafer, and the probing device simultaneously contacts substantially all of the electrical contacts in the integrated circuits. There is a plurality of active switching circuits on the probing device. The module may also have a gas source for supplying non-oxidizing gases such as nitrogen and hydrogen into the chamber, a handler for moving the wafers and the probing devices, and a computer coupled to the chamber for controlling and communicating with the handler, the temperature control devices, the holding fixtures and the probing devices.

  • Patent number: 6838896
    Abstract: 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.
