    Abstract: A substrate is coated with silicon monoxide by heating a source of SiO above 1300 DEG C. and below 1600 DEG C. at a pressure below 10-5 mm. Hg., and preventing deposition of SiO until the desired temperature of the source, e.g. 1328 DEG C., is attained. The process may be applied to forming layers of metals interlayered with SiO which can be used as cryotrons. For example, Fig. 1 shows SiO films 1 deposited between a gate 5 and magnetic shield 3b consisting of layers of lead with a control layer 3a of tin. The coating of SiO is under predetermined stress which is controlled by the rate of deposition, and details including graphs are given which indicate a preferred rate of coating of 4-40 rA per second. Apparatus is described (not shown) provided with three evaporation stations, each station being also provided with a shutter which prevents deposition until the desired temperature indicated by a thermo-couple is reached. Masks to give a desired pattern of coating are also provided. The SiO may be in tablet form with central holes for stacking on a wire support.
