Etching over a photoresist mask produces islands of doped oxide 14, 16 on the substrate on which a layer 18 of SiO 2  is thermally grown; during which As diffuses from islands 14, 16 to form N-type regions 20, 22 in the substrate (Fig. 3) which stand proud of the junction of the oxide layer and the substrate so as to support a raised portion of the oxide layer 18 which is off stripped, e.g. with HF leaving the substrate and upstanding N-type regions (Fig. 4, not shown) serving to locate subsequent masking, on which (Fig. 7) a composite insulant layer of SiO 2  28 overlain with Si 3 N 4  30 and polycrystal Si layer 32 doped with B for high conductivity are deposited, SiO 2  is formed from thermal decomposition of SiH 4 +H, Si 3 H 4  from SiH 4  + BH 3 , and polysilicon from SiH 4  + diborane successively in a simple process tube. Openings are etched over photoresist with HF + HNO 3  + CH 3 COOH in watery solution in layer 32 to admit the gate electrode of a FET with diffusions 20, 22 as source and drain electrodes. A second thermally grown insulant layer 36 is oxidized of the surface of layer 32 whose inner edges are also oxidized. A further photoresist mask is applied to cover the gate opening and to define additional openings which are etched through layers 30, 32, 36 for metallic connections to substrate 10. An aluminium layer 42 is vacuum evaporated into the openings to define the FET gate and the underlying connections, while a further photoresist mask and subsequent etching defines circuitry in the Al layer; isolated portions of which interconnect the layer 32 and the substrate 10. The aluminium is then passivated by sputtering SiO 2  thereon.

Patent GB-751668-A (GB)
Abstract: 751,668. Gravity separation apparatus. STENGEL, E. June 9, 1954 [June 15, 1953], No. 17007/54. Addition to 713,609. Class 111. A sand-trap for the purification of waste water as claimed in the parent Specification is characterized in that the cross-section of the separating chamber is continuously enlarged in the direction of the or each sand-collecting shaft. In an inflow channel 1, Fig. 1, along which waste water flows from right to left, 8 indicates the level up to which the waste water has a high sand-content, 7 the lowest dry weather flow and 6 the maximum level attained. Sand-containing water thus flows into a separating chamber 3 where it is induced to follow a spiral path by an adjustable overflow sill 4, as in the parent Specification, and by an inflow sill 5. As shown in all the Figures the separating chamber 3 increases in cross-section continuously from its closed end to the end containing an inlet 9 to a sand-collecting shaft 10. The mixture of water, sand and sludge emerges first into a prechamber 10a built into the upper part of the sand-collecting shaft. Hence the sand-carrying water flows through pipes 11 to 13, Fig. 2, and past retarding devices 18a, Fig. 3, into the body of the shaft 10, whilst the water with high sludge content flows through pipes 15 to 17 into the upper part of the shaft 10 past retarding devices 18 and thence over a regulating sluice gate 19 into an outlet 20, Fig. 2, leading to the outflow channel 2, Figs. 1 and 2. Material floating in the pre-chamber 10a can, when necessary, be floated off into the outlet 20 by lowering a sluice gate 21, Fig. 3. The sum of the cross-flow cross-sections of the inlets 11 to 13 and 15 to 17 is greater than the cross-flow crosssection of the inlet 9 so that at the former location the spiral motion of the inflowing mixture is not diminished.

Filed: 1979-02-19
Abstract: An ionisation chamber, particularly for use as a smoke detector, comprises a negatively charged electrode 4 and a positively charged filament 1 heated to about 500 DEG C. The heated filament 1 causes the surrounding air to ionise and the difference in charge establishes an ionisation current. The presence of smoke particles in the ionised air causes a reduction in the ionisation current, which is detected and used to indicate the smoke level. As shown, the electrodes 1,4 may be disposed in a perforate cage 2 which is held at a positive potential. Alternatively, Fig. 2 (not shown), the negative electrode may itself be constituted by the perforated cage which surrounds the heater filament. <IMAGE>
