Title: Method of delineating thin layers of material
Inventor: FULS ELLIS NELSON
IPC: H01L29/78
Filed: 1983-10-26
Abstract: A method for delineating thin layers of material, e.g. thin oxide layers, is disclosed. A protective layer of electrically conductive material (60), e.g. of polysilicon, is deposited onto the thin layer of material (30) in order to protect the thin layer against any contamination and/or erosion which might occur during subsequent lithographic processing. The protective layer of material is then patterned, e.g. by means of a resist layer (70) in order to delineate the thin layer of material. The method is particularly suited to forming source and drain contact holes in the gate oxide of FETs, by etching a hole or holes through the thin layer (30) and depositing a further electrically conductive material onto the unmasked protective layer and into the hole(s). <IMAGE>

Title: Process for a thermal treatment of Israeli phosphate rock
Inventor: CARMON SHMUEL
IPC: C01B25/01
Filed: 1985-06-10
Abstract: The present invention relates to a process for a heat treatment of Israeli phosphate rock at a temperature range of between 600 to 700 degrees C. It was discovered that at this temperature range, a substantial part of fulvic acids, present in the organic matter of said phosphate rock, is burnt out. The treated phosphate, is most suitable for the preparation of phosphoric acid by acidulation with a mineral acid by eliminating foaming, the product resulting thereof possessing a pale yellow-green colour. The decreased organic matter content in the treated phosphate imparts a particular advantage in the manufacture of phosphoric acid by solvent extraction, by eliminating the problem of emulsification. The process saves significant amounts of fuel generally required for calcination of phosphate rock.
