Connections to a semi-conductor device mounted in a cavity in an insulating substrate are produced by packing the gap between the sides of the device and the wall of the cavity with a powder, depositing the connections across the powder and then removing the powder. As shown, Fig. 1A, the semi-conductor device 16 is provided with a glass surface layer on which are located terminal lands 12B of aluminium. Corresponding terminal lands 12A are provided on surface 14 of insulating substrate 10 by evaporating through a mask first a layer of chromium and then a layer of aluminium or copper. The gap 20 around device 16 is filled with silicon dioxide powder compacted by means of a vibration tool and then levelled with the surfaces of the device and substrate. Aluminium is evaporated on to the surface of the powder using a molybdenum mask optically aligned with lands 12A, 12B to form continuous connections between them. The powder is then ultrasonically blown or cleaned out of the gap 20 leaving the deposited strips bridging the gap between corresponding ones of the lands 12A, 12B. The semi-conductor device may be a monolithic or other integrated arrangement of silicon and may contain a plurality of active devices, such as transistors and diodes, and may have passive devices, such as resistors and capacitors, formed on its surface. The device is mounted by evaporating a layer of chromium followed by a layer of gold on to the floor of the cavity and providing a layer of gold on the lower face of device 10 so that when placed in position and heated under pressure a gold-silicon eutectic layer 18 is formed. The substrate may be of glass or of a ceramic such as alumina and the cavity may be produced by bonding two sheets of ceramic together, one of the sheets having been provided with an aperture, or by pressing the ceramic before it is cured. The substrate may have pins extending through it which are connected to the conductive lands, and such an arrangement may be mounted on a printed circuit board. The substrate may also be provided with buried conductive layers connected to the surface lands.

Title: Improvements in or relating to processes and apparatus for the production of semi-conductor crystals
IPC: C30B13/12
Filed: 1957-08-12
Abstract: 866,199. Semi-conductors. STE1VIENS & HALSKE A.G. Aug. 12, 1957 [Aug. 10, 1956], No. 25391/57. Class 37. A process for incorporating a doping substance into a semi-conductor melt comprises passing the substance in gaseous form from a storage vessel in which the substance is under pressure through a capillary nozzle into a stream of carrier gas consisting of hydrogen or of other gas inert to the doping substance and to the semi-conductor melt and wherein said substance is conducted together with said carrier gas to a treatment vessel in which the melt is located. The crystal 3 is heated in a reaction chamber to melt it. The doping substance may be BCl a  and is contained in a storage vessel 6. The crystal may be of Si or Ge or of a compound of two or more different metals, the hydrogen can be replaced by a rare gas and any other boron halide such as the bromide BBr 3  can be used. The incorporation of the impurity or " doping " is to give the crystal a particular resistivity to increase the life of the charge carriers or to produce a crystal of a particular conductivity type, and the doping substance is generally distributed uniformly over the surface. In the particular process described the silicon crystal 3 is zone-melted, that is, successive zones of a vertically moving crystal are melted by a high-frequency coil 4. The proportions of carrier gas and "impurity gas" can be adjusted by the pressure in 6, by adjusting the size of the capillary nozzle, e.g. by a needle valve, and by adjusting the rate of flow of the hydrogen or other carrier gas. The final " doped " crystals have accurately-reproducible resistivities over a wide range, e.g. between 1 and 50 ohms/em. In a modification, crystal 3 can be melted in a crucible. In an example a silicon crystal with 10 atoms per cent of boron gives a resistivity of 10 ohms/cm. Prior art methods comprising the steps of conducting hydrogen or a rare gas over a heated liquid halide or mixing the carrier gas with halide gas and then reducing the proportion of the halide by freezing, are referred to.

[Class 38 (iv)] [Also in Group XL (c)] The line frequency generator of a television receiver is maintained constant with respect to the supply frequency by dividing down in a series of relaxation oscillators and compounding the frame frequency pulses and the supply to produce a potential for controlling each oscillator. Fig. 1 shows an arrangement in which a hard valve saw-tooth generator I of the Puckle type produces a saw-tooth of line frequency which synchronizes through a valve 6 the first generator II of a series of similar generators dividing down to frame frequency. The frequencies of the system can be adjusted so that the frame frequency is approximately that of the mains by adjusting potentiometer 7 controlling the screen potential of constant current pentodes 2, 2<1>. The system is locked .on to the mains by adding frame frequency pulses to a supply frequency wave in a device 8 to produce a wave which is rectified to produce a bias proportional to the phase difference between the wave and the pulses by circuit 10, 11 and is then applied to the control grids of the constant current pentodes 2, 2<1>. The operation of the divider chain is checked by connecting the outputs of successive stages to the X and Y-plates of a C.R. tube to produce a trace analagous to Lissajons, Fig. 6 (not shown). Thyratron generators may replace the hard valve generators, Figs. 7 and 8 (not shown), synchronizing pulses for successive stages being derived from resistors in the' cathode leads of the previous valve in these embodiments.
