Abstract: METHOD OF CONTROLLING SILICON WAFER ETCHING RATES A method for controlling the etch rate of a quaternary etchant comprising ethylene diamine, water, pyrocatechol and a diazine. The etching rate is catalyzed and controlled by controlling the amount of the diazine present in the etchant. A method for the controlled etching of silicon is also disclosed. Y0977-055

Abstract: Optical printing of highly conductive lines or characters is described, wherein an organic .pi. -electron donor compound, dissolved in a halocarbon, is deposited onto a substrate. The coated substrate is exposed to actinic radiation in a predetermined pattern, and then the halocarbon is removed. The compositions used are of the type (Donor)xn where the donor is typically selected from TTF, TSeF, DSeDTF, and their substituted derivations where x may be selected from F, Br, Cl and I, and n

Abstract: A method of optically printing conductive characters using charge transfer compounds is provided. The method is characterized by depositing an organic pi electron donor compound dissolved in a halogenated hydrocarbon (halocarbon) on a suitable substrate and selectively exposing the so coated substrate to actinic radiation to obtain a permanent, highly conductive, image.
