Filed: 1964-11-27
Abstract: 1,087,344. Mass spectrometers. ATLAS MESSUND ANALYSENTECHNIK G.m.b.H. Nov. 27, 1964 [Nov. 27, 1963], No. 48320/64. Heading H1D. In an arrangement for sweeping and recording mass spectra in a mass spectrometer by altering the magnetic field, the magnetic field strength is continuously measured by a Hall probe disposed in the magnet gap and the Hall voltage generated is compared with the voltage derived from an empirically calibrated stepped resistance so that the mass number of a recorded peak is correctly identified. A difference voltage is used, after amplification, to operate a relay servo system so that the tapping on the resistance is automatically stepped forward in accordance with the alteration in the magnetic field and, at the same time, the mass indicating device, e.g. a marking pen, a recording galvanometer or a printer, is actuated. Preferably the stepped resistance is calibrated in unitary mass steps. The Hall probe is temperature compensated.

The vapour deposition is carried out in two stages, each stage using its own source which is totally evaporated. In the first stage the surface temperature of the wafer is allowed to rise above a eutectic temperature and in the second stage (effected without breaking the vacuum) the temperature is kept below that of any eutectic. The surface of the wafer may be blasted with alumina particles before coating. Semi-conductors suggested are silicon, germanium, and gallium arsenide. The contact metal, which may be doped with aluminium, gallium, or antimony, may be gold or gold containing between I wt. per cent and 10 wt. per cent silicon or chromium or between 1 wt. per cent and 18 wt. per cent germanium. In the case of gold-silicon, the alloy source must be evaporated rapidly if the deposit is to be of similar composition, because of the low vapour pressure of silicon.
