Abstract: USE OF DEPOLYMERIZABLE POLYMERS IN THE        FABRICATION OF LIFT-OFF STRUCTURE FOR              MULTILEVEL METAL PROCESSES     ABSTRACT     An improved lift-off process for multilevel metal structure in the fabrication of integrated circuits by employing lift-off layer  formed from polymers which undergo clean depolymerization under the influence of heat or radiation and allow rapid and residue-free release of an "expendable mask".  An embedded interconnection metallurgy system is formed by application of the lift-off layer of this invention over a cured polymer film or on an oxygen RIE barrier layer previously deposited on organic or inorganic substrate, followed by another barrier over which is then coated a radiation sensitive resist layer.  After definition of the desired resist pattern by imagewise exposure and development, the image is replicated into the barrier by sputter etching in a fluorine containing ambient and subsequently into the base layer down to the substrate by oxygen reactive ion etching which is followed by blanket metal evaporation and finally the lift-off by brief heat treatment at the depolymerization temperature of the lift-off layer, and brief solvent soak.

Abstract: CATALYTIC COMBUSTOR HAVING SPIRAL SHAPE  ABSTRACT    The combustor comprises a single sheet of metal coated with catalyst and wound into a spiral.  There is a single spiral passage leading into the core of the spiral.  The fuel-air mixture burns on the catalyzed surface of the spiral, and heat is transferred through the metal wall of the spiral to the incoming fuel-air mixture.  The incoming fuel-air mixture is preheated to a temperature sufficient to start the catalytic combustion.  The fuel content in the mixture can be below the flammability limit.  The com-bustor is compact so that it can be used as a catalytic air preheater in a downhole steam generator,

Abstract: Separating Hydrocarbon Gases Abstract The present invention relates to a process for separating a hydrocarbon gas into a fraction contain-ing a predominant portion of the ethane and lighter components and a fraction containing a predominant portion of the C3 and heavier components in which process the feed gas is treated in one or more heat exchange, and expansion steps to provide a partly condensed hydrocarbon gas comprising a first residue vapor and a C3-containing liquid which liquid also contains lighter hydrocarbons; the partly condensed feed gas is directed into a separator wherein the first residue vapor is separated from the C3-contain-ing liquid; and the C3-containing liquids, at substan-tially the pressure of separation, are directed into a distillation column wherein said liquid is separated into a second residue containing lighter hydrocarbons and a C3-containing product.  In accordance with the present invention the foregoing process is improved by cooling said second residue to partially condense it; directing the partially condensed second residue into said separator forming thereby a liquid portion and a vapor portion; intimately contacting at least the first residue vapor with at least the liquids portion of the partly condensed second residue in at least one contacting stage within said separator, and thereafter separating the vapors and liquids from said contacting stage; supplying the liquids thereby recovered to the distillation column as a top liquid feed thereto: and directing the vapors thereby recovered into heat exchange relation with said second residue from the fractionation column, thereby to partly condense the second residue, and thereafter discharging said residue gases.

Abstract: THERMAL STABILIZATION OF PHOTORESIST IMAGES                ABSTRACT OF THE DISCLOSURE     Application of a high temperature resistant film forming polymer has previously proved successful  in stabilizing photoresist image layers, particularly those used for high resolution geometries in microelectronic applications,  against distortion or degradation by the heat generated during subsequent etching,  ion implanta-tion processes and the like.   It has been found that, when the thickness of the photoresist image layer exceeds about 1 micron, the coating of the film forming polymer tends to distort and or cause cracks, breaks and the like in the photoresist resulting in loss of the required geometry in the image.  In accordance with the invention this problem can be overcome by applying the film forming polymer in the form of an ultrasonically atomized spray under controlled conditions.
