Title: Process and apparatus for diffusing boron into silicon for the purpose of producing semiconductor devices
IPC: H01L21/00
Filed: 1965-05-25
Abstract: In a process for diffusing boron into silicon from trimethyl borate, contamination with carbon is prevented by either (a) passing the inert gas carrying trimethyl borate through a tube maintained at at least 900 DEG  C., e.g. of quartz, where carbon is deposited, before passage over the heated Si, or (b) mixing streams of inert gas carrying trimethyl borate and water as they enter the heated Si-containing zone, so that carbon reacts with water to form CO and CO2.  The inert gas, e.g. N2 or A, may be charged by bubbling through, or surface contact with, a solution of trimethyl borate at -10 DEG  C.  The Si is first cleaned optically, chemically and by ultrasonic vibrations.  In (a) an inert gas charged with water is also passed over the Si, to prevent decomposition of CO.  In examples, the temperature of the Si is, in (a) 1280 DEG  C. and in (b) 1150 DEG  C.

Abstract: 1429865 Modulated radiation source COMMISSARIAT A L'ENERGIE ATOMIQUE 10 May 1973 [19 May 1972] 22375/73 Heading G1A A material under test is irradiated by radiation varying cyclically in intensity is provided by moving radiation-emitters and "dummy" sources (non- emitting bodies of same size and density as the emitting source) sequentially and repetitively past the object of location. Any wave or particle radiation is envisaged, but the invention is described with reference to a 7-ray absorption gauge for measuring the concentration of heavy elements in a solution which also contains spurious 7-ray emitters. These interfere with the absorption measurement and may be eliminated to a certain extent by the use of modulated radiation and subsequent synchronous demodulation of the detector output. However, some spurious γ- radiation from the sample can be reflected from the modulator (chopper) back through the sample to the detector and is synchronously detected with the main measurement signal. To avoid this the "dummy" sources are provided. As shown in the Fig, two γ-emitters (e.g. of Am<SP>241</SP> oxide) are mounted at locations 3 in rotating disc 1, while a pair of "dummy" sources, are mounted in the other quadrants 12 of the disc. When in the test position (shown dotted), the disc 1' is rotated by motor 2, to pass the emitters and "dummy" sources past the cell 4 through which the sample is passed, the transmitted radiation being sensed by a thin scintillator element 7 and photo-cell 8. When a "dummy" source is opposite the cell, γ-rays from the emitters 3' are shielded by plate 5. The spurious signal due to reflected γ-rays, is in phase with the main signal, but the dummy sources provide a further spurious signal of the same intensity as the spurious signal caused by the emitters, by nature of the density equivalence but 90 degrees out-of-phase with this so that detection thereof can be used to connect the main measurement. In order to carry out a concentration measurement according to the Formula I=I o  exp (-KC), I is measured in the test position and I o  in the reference (full line) position of the source-detector arrangement which is moveable parallel to plate 5. The invention may also be useful in fluoresence (e.g. x-ray) analysis, where spurious background exists.
