Abstract: 1294889 Semiconductor devices SIEMENS AG 3 Dec 1969 [4 Dec 1968] 58969/69 Heading H1K The surfaces of bodies of silicon, germanium, A<SP>III</SP>B<SP>V</SP> compounds and A<SP>II</SP>B<SP>VI</SP> compounds in devices such as diodes, transistors, thyristors, and bilateral thyristors tend to be coated with an oxide film containing moisture. In the vicinity of reverse biased junctions atomic hydrogen is discharged at the interface between oxide and body. Divalent lead ions, which catalyse the conversion of the atomic hydrogen to the harmless molecular state, are introduced to the interface by coating the body with a material containing a source of lead ions and a material which renders the oxide film permeable to the lead ions. The lead source may be Pb 3 O 4 , PbCO 3 , Pbo, lead stearate, lead acetate, lead napthenate, lead alizarinate, or lead quercetinate. Permeability additives are vicpolyhydroxy compounds such as alizarin, mannitol, sorbutol, and quercetin, derivatives and compounds of these polyhydroxy compounds, and substances yielding phosphate ions such as ammonium phosphate or tricresyl phosphate. These materials may be dispersed in rubber, a silicone resin such as phenyl methyl polysiloxane condensed with an alkyd component, silicone rubber, or varnish in which which also may be dispersed weak acid salts (stearates) of Na, Mg, Ca, Sr, Ba, Al, and Ga, strong acid salts of these elements, or weak acids such as stearic acid and alizarin. In an embodiment a psn diode is jet-etched with a mixture of 40% HF and 96-100% fuming HNO 3 , is washed in water, and dried. The body, with its reformed oxide skin, is then coated with a toluene, xylene, cyclohecanone, or cyclohexanol solution of a liquid or plastic insulant and the various additives. The solvent is removed and the insulant may either be hardened or, if a housing is provided, left in the plastic state.

Abstract: The continuous process for hyperactivation of fluids for sterilization uses a sterilizing fluid which is mixed with a gas that is inert with respect to the fluid. A sterilizing mixture is obtained which is subsequently evaporated by means of introduction into an evaporation tube in a condition of annular motion, where a liquid phase of the mixture flows against the heated walls of the evaporator at a slower speed than the gaseous phase thereof, which flows in the central zone of the evaporator, internally of the liquid phase. A gaseous vapour/inert gas mixture is thus obtained, which is subjected to a waiting period during which the mixture flows through a transit device which transfers it to a sterilization chamber, a temperature of which is lower than a dewpoint temperature of the gaseous mixture, where a product is sterilized.
