Abstract: A sealing frame arrangement is disclosed for creating a hermetic seal between two components or bodies such as a connector and heat sink module of an integrated circuit package. The frame members are configured to fit together along facing surfaces and to be joined to the two bodies along the inner edge of their outside (non-facing) surfaces. The sealing arrangement is completed by a third seal formed along the outer facing edge of the frames. The frames extend a sufficient distance beyond the two components to permit severing the frames inside the third seal and resealing. Preferably, the frames are of sufficient width to provide a multiplicity of sealing regions so that the third seal can be broken and resealed a number of times. The seal frames may be of stepped or corrugated configuration in which the individual seals are formed along the mating steps.

Abstract: A Hall effect pressure transducer incorporates a pressure-deflection diaphragm which has patterned depressions therein to enhance linearity of response; an O-ring diaphragm seal which seals the diaphragm against pressure leaks without affecting the linearity of response; a pair of magnets, preferably rectangular, oriented with their North-South axes oppositely parallel, and oriented transverse to the deflection axis of the diaphragm to provide a uniform magnetic field gradient and sensitive, accurate, linear response of the transducer to either positive or negative pressure-induced deflections of the diaphragm.

Abstract: A manual resuscitator is disclosed which includes two disposable bellows having appropriate valves which connect via a chamber to a patient mouthpiece or face mask. The bellows are inserted into a frame comprising a manually-operated telescoping push rod and a return compression spring. When the push rod is moved upward, assisted by the return compression spring, fresh air is drawn into and stored in the inhale bellows and, simultaneously the contents of the patient's lungs are sucked into the exhaust bellows. When the push rod is pushed down, both bellows compress and, as a result, the inhale bellows forces the stored fresh air into the patient's lungs while the exhale bellows forces air plus carbon dioxide, water, smoke, etc., from the patient's lungs into the atmosphere. The inhale bellows is adapted to limit the maximum vacuum suction during exhaling. Also, the exhale bellows is adapted to limit the pressure of the fresh air forced into the patient's lungs.

Abstract: A photorefractive crystallyte array for image recording and signal processing is disclosed.

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 is disclosed. 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 or 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.

Abstract: A vertical window covering system which utilizes an area of prepleated drapery fabric having permanently set pleats of a nature such that the fabric behaves like a tension spring tending to bias pleats toward the folded state or a vertical blind with taped or string ladders.

Abstract: A memory FET device having a channel implantation which controls gate parasitic transistor action. The parasitic action produces unwanted conduction paths which are formed in the transition regions between the thin memory oxide and the thick field oxide and extend along the sides of the gate region between the source and the drain. By blanket implanting through the oxide, which is relatively thin in the memory oxide region and increases in thickness across the transition region, and by adjusting the implant threshold, a continuous implant layer is formed which lies (1) within the field oxide, (2) at the substrate surface beneath the transition region oxide, and (3) deep within the body of the substrate beneath the gate region.

Abstract: A process for reworking the upper level metal layer of an integrated circuit wafer having multiple levels of metal connected by vias through intermediate dielectric layers. In one form, a photoresist masking layer is first formed over the defective upper level metal using an expanded reverse field pattern of the vias. The wafer is then subjected to a metal etch to completely remove the exposed upper level metal while etching into the metal under the photoresist until the etching enters the metal in the via. Thereafter, the residual photoresist is removed. The rework process is concluded with a single chamber operation composed of a sputter etch followed by the deposition of new upper level metal. The concluding chamber sequence ensures the proper via metal surface conditioning for reliable deposition bonding of the new upper level metal deposited thereon.
