  • Patent number: 5053282
    Abstract: Disclosed is a non-inflammable insulating, composite material capable of being shooted onto a surface to be coated, such as the wall of a building to be insulated. This material comprises a fibrous-like, synthetic forsterite obtained by calcination of chrysolite asbestos fibers at a temperature from 650.degree. to 1450.degree. C.; an inorganic, lightweight filler selected amongst vermiculite, perlite and their mixtures; and a non-inflammable, hydraulic or silicate binder contained in such an amount as to make the material sufficiently adhesive to be shooted as a coating, either as such or after wetting, onto the surface to be insulated. The weight ratio of the synthetic forsterite to the inorganic filler is ranging from 20:80 to 80:20 to adjust the volumic weight of the final product from about 0.20 to about 0.50 gram per cm3. Also disclosed are methods of manufacturing such a non inflammable, insulating, composite material in a wet, ready-to-be-shooted form.

  • Patent number: 4889832
    Abstract: A process for forming backside contacts includes first forming an etch stop layer (12) beneath the surface of a silicon substrate. An active circuit is then formed in the silicon surface and associated metal interconnecting layers formed on the upper surface of the substrate. A planarizing layer is then formed on the upper surface of the substrate which is operable to be connected to a mechanical support. Thereafter, the backside of the substrate is etched away up to the etch stop layer (12). The thickness of the remaining substrate between the metal layers on the upper surface and the etch stop layer is sufficiently thin that the alignment marks on the upper surface can be seen through the substrate. These alignment marks are utilized to form vias from the backside to the active elements and then deposit and pattern interconnecting layers on the backside.

  • Patent number: 4883774
    Abstract: A process for flashing a thin layer of silver on metal leadframes using no mask steps and a minimal amount of silver. An unmasked metal leadframe is placed into a cleaning bath that includes silver in solution and has no outside electrical driving force to assist plating. The leadframe is removed from the cleaning bath once a uniform silver layer having a thickness of 100 to 1000 angstroms is plated thereon. The silver layer need not be exact and, therefore, it is not critical that the period of time the leadframe remains in the cleaning bath be exact.

  • Patent number: 4879259
    Abstract: A method of annealing a wafer in a rapid thermal annealer is disclosed. The walls of the chamber are heated more rapidly than is the wafer. In a preferred embodiment, the interior of the graphite walls of the annealer is lined with a molybdenum sheet which is open toward the lamps that heat the chamber. Thus, the walls heat very rapidly to a temperature greater than the condensation point of arsenic, preventing arsenic condensation on the walls. Effective annealing can be achieved at wall temperatures in the range of 500.degree. to 600.degree. C. Prior to the heat ramp up, an arsenic atmosphere, preferably trimethylarsenic (TMAs) at an appropriate overpressure is introduced. This overpressure is maintained both during the heating and cooling cycle. By the use of this method, the exposure time for annealing can be reduced from prior times of as much as 20 minutes to as little as 10 seconds.

  • Patent number: RE33737
    Abstract: The coated optical fiber of the invention is prepared by providing a coating layer of an ultraviolet-curable organopolysiloxane or a composition comprising the same and irradiating the coating layer with ultraviolet. Specifically, each of the terminal silicon atoms of the organopolysiloxane, which preferably has a linear molecular structure, has two or more ethylenically unsaturated polymerizable groups bonded thereto through an oxygen atom, such as CH.sub.2 .dbd.CHCOOCH.sub.2 CH.sub.2 --, [CH.sub.2 .dbd.C(CH.sub.3)COOCH.sub.2 ].sub.3 C--CH.sub.2 -- and (CH.sub.2 .dbd.CHCOOCH.sub.2).sub.2 C(C.sub.2 H.sub.5)CH.sub.2 --. By virtue of this unique molecular structure of the organopolysiloxane, the coating layer is rapidly cured by ultraviolet irradiation to give a cured coating layer exhibiting very low water absorption and small temperature dependency of the Young's modulus at low temperatures.
