Abstract: 1,013,840. Photo-sensitive devices. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Jan. 23, 1963 [Jan. 26, 1962], No. 2880/63. Heading H1K. A photo-cell in which a photosensitive body provided with electrodes on at least an active portion thereof is embedded in an insulating, liquid or soft, filler is manufactured by reducing the ambient pressure of the body below atmospheric to remove gas inclusions and subsequently increasing the pressure in the embedded contion. In the embodiment (Fig. 1) a plate-shaped body of pressed and sintered cadmium sulphide, or selenide, provided with two comblike electrode systems 7 and 8 deposited from the vapour phase on one side thereof, is mounted between two nickel-clamping members 9 and 10 connected to supply leads 3 and 4 and embedded in a silicone oil or grease 11 within a glass envelope 1. In manufacture, a glass envelope partly filled with a soft filler (Figs. 2A and 2B, not shown), is arranged in a centrifuge and connected to a pump system. The plate and leads assembly is mounted on the filler in the envelope and the pressure in the system is reduced to about 10<SP>-4</SP> mm./Hg. and the centrifuge operated to embed the body assembly into the filler mass, after which the pressure is restored to atmospheric. The photosensitive body which may be made by deposition of the semi-conductor material from the vapour state on to a support, may be encapsulated in a hardenable epoxy resin which eventually forms the envelope.

Sequence of operations. A support layer and a framing mould are placed on the vacuum table 38 and vacuum applied through a duct 112. A carriage 40 is traversed to the right (as seen in Fig. 10), and on contacting a switch 56, a tube 44 and the dispenser 48 pivot about the axis of the dispenser to uncover slots through which warmed photo-curable composition is dispensed. The composition is continuously agitated prior to supply to prevent the entrapment of air. When the carriage 40 contacts a switch 58, dispensing is terminated and the members 44, 48 returned to the position shown. The carriage 40 is then traversed to the left (i.e. back to the position shown in Fig. 10) whereby the doctor blade 117 levels the composition on the vacuum table 38 and then a stream of heated air from a chamber 98 removes surface bubbles. Movement of the carriage past the switch 56 turns off the air stream. Excess composition is scraped off into a trough 118 which is later shielded from the actinic light so that the composition therein can be reused. If desired, a spacer may be positioned on the filled mould. The frame 94, to which a transparency adheres by suction is lowered. A bar 18 for generating ions to prevent static electricity accumulating on the transparency is provided. The exposure is made and the vacuum to the table 38 shut off to remove the support and photo-cured composition from the apparatus.
