Inventor: LEVY ROLAND ALBERT
IPC: H01L21/8234
Filed: 1987-08-17
Abstract: A material such as boron nitride is conformally deposited and then patterned to form adherent portions (22) on the sidewalls of high-aspect-ratio vias (18) formed in a dielectric layer (16) of a CMOS device. A conductive material such as tungsten is then selectively deposited in the vias on the boron nitride and on silicon or silicide at the via bottoms. In some cases, the deposition of tungsten is controlled to fill the vias thereby leaving an advantageous substantially planar surface for subsequent metallization.

Abstract: Silicone fluid-based electric insulating oils can be imparted with greatly enhanced flame retardancy when the base organopolysiloxane contains 0.1 to 30% by moles of vinyl groups relative to the monovalent hydrocarbon groups bonded to the silicon atoms and is admixed with a platinum compound soluble therein, such as chloroplatinic acid, dissolved therein in a specified amount. The flame retardancy of the organopolysiloxane/platinum compound composition can be further improved by the addition of a low-viscosity fluorinated hydrocarbon oil such as an oligomeric polymer of chlorotrifluoroethylene.

Inventor: BOURNE RICHARD C
IPC: F24D11/02
Filed: 1987-03-24
Abstract: This invention relates to a three-function heat pump system which provides space heating, space cooling and hot water. The system permits hot water production all year long of the heating or cooling modes of the system. To this end, the system employs a large storage tank (50) and a relatively smaller hot water tank (20). A heat exchanger (21) within the hot water tank (20) is sized sufficiently to permit the hot water heat exchanger (21) to function as a system condenser, thereby permitting the refrigerant to bypass the large storage tank (50). The system is packaged in a compact unit in which the compressor (10) of the system is located wtihin an insu­lated container with the domestic hot water tank (20). The crankcase of the compressor (10) therefore remains warm to prevent migration of the refrigerant to the compressor (10) during off seasons. The location of the compressor (10) adja­cent to the hot water tank (20) eliminates the need for less energy efficient resistance crankcase heaters.

Abstract: The present invention relates to a method for making an improved thermal insulation character­istic wadding, particularly designed for making cloth, furniture and the like articles, which com­prises the step of preparing, by means of carding machines, a lap consisting of a mixture of poly­ester or other nature fibres, which have been possi­bly siliconized, and subjecting this lap to a sub­sequent resin treating step, on at least a face thereof, by using cross-linked glues. 
     The resin treated lap is then calendered, under controlled temperature and pressure conditions, so as to obtain, on its surface, a soft and resilient film and, inside it, an air chamber so as to pro­vide a low thermal exchange coefficient and, ac­cordingly, a proper temperature controlling of the body temperature.

Abstract: A slider type fuse for a cargo warhead gre­nade. The slider (14) is slidable in a plane normal to the axis of the striker pin (12) and carries additional to the detonator (15) a pyrotechnic device comprising an igniter charge (17), a booster charge (18) removed therefrom and located in close proximity to the detonator (15), a delay charge (19) between the two and swingable striker means (20) which become unlocked in the armed state and are adapted to strike the igniter charge (17) in consequence of centrifugal forces that develop in the course of flight. The delay of the pyrotechnic device is designed to outlast the flight time of the grenade. Whenever the striker (12) does not strike the detonator (15) when the grenade hits the target, the detonator (15) is initiated by the booster charge (18) or the pyrotechnic device.

Abstract: A paperboard carton (8) for containing and pouring liquid has a pour spout fitment (12) adhesively secured to its upper surface (20) and at least partially over a reinforcing patch (22) on said upper surface to spread the upward force exerted by opening the fitment over an area of the carton surface larger than the bottom surface (26) of the fitment so as to prevent the fitment from being torn away from the carton surface. In addition to the force distribution, the tensile strength of the added patch material is much greater than the stength of the carton coating, thus this new patch material becomes the primary seal.

Abstract: A positioning system having a velocity feedback loop for positioning an object is described in which numerical operation is employed. The positioning system generally has two modes - - a high speed moving mode and a fine moving mode. The system requires a wide range in the high speed moving mode and a high resolution in the fine moving mode. To satisfy these inconsistent requirements, the gain of a velocity sensor in the feedback loop is varied according to the mode. The gain is decreased in the high speed moving mode, and increased in the fine moving mode. This system is effectively used to control an optical head of an optical disc player.

Abstract: A via connection and method for making the same for integrated circuits having multiple layers of electrically conductive interconnect lines (16,18) separated by an insulative layer (32). The via connection has a very thin layer (36) of relatively high resistivity material lining the via hole (30) in conductive contact with interconnect lines in two layers. The resistivity of the thin layer material is in a range from about 10 to about 50 times the interconnect line resistivities and generally has a thickness of less than 100 nanometers. The thin layer assures more uniform current flow in the via connection thereby preventing electromigration, with reduced peak local current density by causing current to swing more widely around the corner at the interface between the interconnect lines at the via.

Abstract: A laser end point detector incorporating adjustable-­focus, variable-orientation detection optics for monitoring different types of structures such as laser-transparent thin films, isolated trenches or holes and patterned arrays of trenches or holes. A collector lens package comprising a laser and a focusing lens are mounted in a hole in a collector lens which is pivotally mounted for selectively focusing zero, first and higher orders of diffractions reflected from the wafer onto an associated detector to monitor the etching of different types of structures. For example, zero order diffraction signals are used to monitor the etching of large target areas in transparent thin films or of non-patterned trenches of holes. First order (or higher) diffraction signals are used for monitoring the etching of patterned features which effect a two-dimensional diffraction grating, such as the capacitor holes in dynamic random access memories.
