Abstract: 1,274,975. Semi-conductor devices. TRANSISTOR A.G. 3 April, 1970 [9 April, 1969], No. 15869/70. Heading H1K. At least one "physical" gettering layer is provided by roughening, a surface of a semiconductor body during the various heating processes involved in device manufacture and the temperature and rate of cooling in the final heating process is adjusted to control the amount of outdiffusion of impurities which produce recombination centres, thereby obtaining a desired value of charge carrier life-time in the device. The outdiffusing impurity may, for example, be Cu in Ge or Au in Si. In the particular embodiment the manufacture of a Si thyristor is described, the process commencing with Ga diffusion into both faces of an N-type Si body, followed by the roughening of at least one surface by lapping with 5Á grains to produce the "physical" gettering layer. An annular P-doped cathode region is then diffused through a SiO 2  mask into one of the Ga-doped end regions, and the phosphorus glass layer formed during this process constitutes a "chemical" gettering layer in addition to the "physical" gettering layer. Subsequently a P + gate contact region is formed by masked B diffusion into the surface area surrounded by the annular cathode region, and the exact temperature and cooling rate used during this diffusion are controlled so as to result in the desired value of charge carrier lifetime. Finally electrodes are provided, no significant heating occurring during this stage. Diodes and transistors having controlled carrier lifetimes are also referred to.

Title: Manufacture of imidazolines
Filed: 1946-05-28
Abstract: 2 - (N - Aryl - N - aryl-aminoalkyl) - imidazolines are prepared by reacting on N-aryl-N-aralkylaminoalkane carboxylic acid or its imino-ether, imino-halide, thioamide, thioimino-ether, amide, ester, halide, amidine or nitrile with an aliphatic diamine in which the two amino groups are attached to vicinal carbon atoms and in which one of the amino groups may be monosubstituted. When a nitrile is used, it is advantageous to react it in the presence of hydrogen sulphide or an agent capable of yielding hydrogen sulphide during the reaction, e.g. carbon disulphide, phosphorus pentasulphide, an alkali sulphide, an ammonium sulphide, iron sulphide or aluminium sulphide.  The quantity of hydrogen sulphide employed may be less than that which corresponds to equimolecular proportions of the nitrile and hydrogen sulphide. The reaction may be effected in the presence or absence of a diluent and/or a condensing agent, at low or raised temperatures and under various pressures.  The desired imidazolines may also be prepared by treating the corresponding diamine acylated with N-aryl-N-aralkyl-aminoalkane carboxylic acid with an agent capable of eliminating water, e.g. calcium oxide.  In examples, the preparation of the following compounds is described: 2 - (N - phenyl - N - benzyl - aminomethyl) - imidazoline and its hydrochloride, 2-[N-(21-methoxyphenyl) - N - benzyl - aminomethyl]-, 2 - [N - (41 - methoxyphenyl) - N - benzyl - aminomethyl]-, 2 - [N-(21-ethoxyphenyl)-N-benzyl-aminomethyl]-, 2 - [N - (41 - ethoxyphenyl) - N - benzyl - aminomethyl]-, 2-[N - naphthyl - (11) - N - benzyl - aminomethyl]-, 2-[N-phenyl-N-benzyl-aminopropyl]-, 2 - [N - phenyl - N - phenylethyl - aminomethyl]-, 2-[N - (31-oxyphenyl) - N - benzyl-aminomethyl]-, 2 - [N - (41 - phenoxyphenyl) - N - benzyl - aminomethyl]-, 2-[N - naphthyl-(21) - N - benzyl-aminomethyl]-, 2 - [N - phenyl - N - (41 - chlorobenzyl) - aminomethyl]-, 2 - [N - (41 - chlorophenyl) - N - (411 chlorobenzyl)-aminomethyl]-, and 2-[N-phenyl-N - (41-methoxybenzyl)-aminomethyl]-imidazoline hydrochlorides.
