A layer of silicon is epitaxially formed on a silicon substrate of one of the conductivity types by diffusing carriers defining the other conductivity type into the surface of the substrate and thereafter epitaxially depositing silicon on the substrate by directing a mixture of a silicon halide gas and a reducing gas against the surface of the substrate and reacting the gases by heating. Diborane may be used as a P-type doping agent, phosphene as an N-type.

Abstract: 1,051,972. Self-propelled missiles. WASAGCHEMIE A.G. March 5, 1964 [March 9, 1963], No. 9425/64. Heading F3A. [Also in Division F1] In a rocket propulsion system, a propellent gas is obtained in a first stage by the thermal decomposition of an endothermic compound which is substantially free from oxygen, the propellent gas being subsequently oxidized in a second stage. The propellent gas has the ratio of its gas constant R to its molecular weight higher than 40, R being defined by the gas law PV=RT. In the first stage a conventional propellant or an explosive with an exact oxygen balance or an oxygen deficiency may be provided for initiating the thermal decomposition. An electric spark may also be provided for this purpose. The second stage comprises a combustion chamber in which the propellent gas is burnt with oxidizing agents. Self-ignition upon contact of the propellent gas and the oxidizer may occur. The oxidizer may comprise oxygen, an oxygen carrier or an oxidizer containing no oxygen. If the oxidizer comprises liquid oxygen, it may be used for cooling the nozzle. The supply of oxidizer may be varied to control the thrust. As shown in Fig. 1, the oxidizer may be air introduced into the combustion chamber 5 through an intake 4 by ramjet effect. Hydrazine from container 1 is decomposed in a chamber 3 before being oxidized in the combustion chamber. When starting the engine, the intake 4 may be closed by escaping gas generated by an additional oxidizer together with the reducing gases of the first stage. In another embodiment, Fig. 2 (not shown), liquid oxidizer is fed by a pump into the combustion chamber from a container mounted above the hydrazine container, the intake 4 being omitted. The pump is operated by a turbine which in turn is operated by part of the decomposition products from the first stage. In Fig. 3 (not shown), the decomposition products pass through a solid oxidizer, which forms a lining of the combustion chamber. As shown in Fig. 4. a hollow cylinder 1 of solid, endothermically decomposing propellant is provided with an inner lining 2 of initiation charge. Decomposition products form in a chamber 5, which communicates through a pipe 3 with the oxidizer container 4. The pressure in chamber 5 acts through pipe 3 to feed oxidizer through another pipe to the combustion chamber 6. A list of possible propellent gas generating compounds and oxidizers is included in the Specification.

Specified solid plasticizers are tricyclohexyl citrate, N-cyclohexyl p-toluene sulphonamide, N-phenyl p-toluene sulphonamide, N-cyclohexyl benzene sulphonamide, dicyclohexyl phthalate or dicyclohexyl tartrate. The lacquer may also contain a resin.
