Abstract
1324416 Semi-conductor devices MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 20 Aug 1970 [21 Aug 1969] 40145/70 Heading H1K An electric memory or storage device comprises a disc body of resin having electrodes on opposite or the same surface (Figs. 1, 2, not shown) comprising finely divided conductive particles dispersed in the resin. On application of increasing voltage to the electrodes the device exhibits high resistance and current increases ohmically to point 30 (Fig. 3) and further voltage increase shifts the working point to 40 from which current again increases ohmically, and the device exhibits low resistance until voltage reaches point 50, after which further increase in voltage shifts the working point to 60 on a further ohmic characteristic, along which voltage and current may be reduced to zero; the device remaining in this "memory" state for successive cycles of increasing and decreasing voltage and current until restored to its high resistance state by heating to a temperature exceeding the glass transition temperature of the resin. The device is responsive to pulse voltages, and the resin contains chlorine or bromine atoms. Preferred mixtures are: polyethylene, polystyrene, polymethyl methacrylate, polyacetal, polycarbonate, polyamide, polyester, phenol formaldehyde, epoxy resin silicone resin, alkyd resin, polysulphide resin, polyphenylene oxide resin, admixed with low M.W. chloro or bromo compounds such as chlorinated paraffins, chlorinated fatty esters, chlorinated fatty alcohols, chlorinated fatty amines, chlorinated amides, 1,2,3-tribromopropane, 1,2-dibromochloropropane, 1,2,3,4-tetrabromobutane, 1,2- dibromo - 1,1,2,2 - tetrachloroethane, tris - (2- chloroethyl) phosphate, perchloro-pentacyclodecane. Alternatively, the resin may be a chlorine or bromine containing vinyl polymer such as polyvinyl chloride, polyvinylidene chloride, polyvinyl bromide, poly-p-chlorostyrene, or a chloro-substituted polyolefine such as chlorinated polyethylene, chlorinated polypropylene; or chlorine or bromine containing epoxy resins; or chlorinated natural rubber; and the finely divided particles may be of silver, iron, copper, carbon black, or graphite. The body is formed by solution of resin in a suitable medium, introduction of the finely divided particles, mixing in a ball mill to a paint applied to an electrode substrate, evaporation of solvent, and imposition of a further electrode by vacuum deposition of e.g. aluminium, or by conductive ink. Alternatively the solvent is heat evaporated from the paint to form a film on which electrodes are similarly imposed. Specification 1,324,417 is referred to.
