Title: Semiconductor device and methods of fabrication

Abstract: 1,014,734. Semi-conductor devices. TEXAS INSTRUMENTS Inc. Oct. 19, 1962 [Oct. 20, 1961], No. 39642/62. Heading H1K. A body of semi-conductor material is contained within a glass shell with leads connected to the body, and the shell is filled with a glass covering composed of fused glass powder. In fabricating a transistor, three leads 11, 12, 13, Fig. 1, are welded to a holding ring 10. The leads are of nickel clad with silver. A planar silicon transistor element 14 is bonded to lead 12 by placing the two in contact and heating to the silver-silicon eutectic temperature of about 830‹ C. Element 14 comprises a collector region 15, Fig. 3, two diffused regions 16, 17, and a silicon oxide layer 18 covering the top surface. Emitter and base contacts 19, 20 are provided by the evaporation of aluminium in areas where the oxide layer 18 has been selectively removed by etching. Wire 21 is attached to emitter contact 19 by ball bonding and to lead 11 by spot welding. Wire 22 is similarly attached to base contact 20 and lead 13. Element 14 with the attached leads is placed within a glass can or shell 24 made of potash soda lead glass having a thermal expansion coefficient of 89 x 10<SP>-7</SP> per ‹ C. and a softening point of 630‹ C. The shell 24 is filled with a slurry of finely ground solder glass, a solvent (amyl acetate) and, if desired, a binder such as nitrocellulose. The solder glass has a melting point less than that of the shell 24 and may be a combination of materials including SiO 2 , PbO, Al 2 O 3 , B 2 O 3 , ZnO, and gold (trace) to aid crystal formation. A suitable solder glass is a high lead glass which softens at 440‹ C. and has a thermal expansion coefficient of 84 x 10<SP>-7</SP> per ‹ C. Any two types of glass may be used for shell 24 and solder glass provided their thermal expansion coefficients are approximately equal and the softening points are adequately separated. The assembly is allowed to stand so that the solvent evaporates and the solder glass is then fired, e.g. at 440‹ C., to fuse the glass powder and burn out any binder. The device is then removed from ring 10 by clipping leads 11, 12, 13. The contacts and leads may be of silver, platinum or palladium. Instead of a transistor, a diode or a multielement semiconductor network may be provided. Two transistors may be encapsulated in the same shell. The shell may be of rectangular configuration.

[Also in Division G1] In an arrangement in which patterns (e.g- Alpha-Numeric symbols, Fig. 2) determined by control signals operative on the vertical and horizontal beam deflection means are " painted " on the screen of a cathode-ray tube CRT (Fig. 1) and optically directed on to a record medium RM, the directions and magnitudes of the deflections required for (each limb of) the symbols are derived from a Data Source DS and set up in registers in the vertical and horizontal deflection control circuits VDC, HDC in terms of co-ordinate positions in an arbitrary grid (16,384 horizontal positions and 255 vertical positions, as seen on the CRT screen), the registers feeding comparators which also receive inputs from further registers in which the actual grid-point movements of the beam as determined by vertical and horizontal position transducers VIT, HIT responsive to beam movement are set up in similar terms the comparators operating whilst inequality exists between the two inputs to to supply output signals (the control signals) to cause the vertical and horizontal deflection generators to produce the deflections required to " paint " the symbol. The beam is thus precisely positioned during each deflection movement and if, e.g., due to pin-cushion distortions, a deflection movement of the beam occurs which is not set up in the register by the Data Source DS the detection of this movement by the appropriate transducers VIT, HIT causes a correction deflection movement to be imparted to the beam. The transducers VIT HIT each comprise, as shown in Figs. 1 and 3, in respect of transducer VIT a pair of photo-sensitive elements PE1, PE2 screened from each other by means of a baffle 18 and each receiving through a grating 12 a respective one of beams B8, B9 with the relationship shown in Fig. 3 so that a known signal processing circuit 20 is enabled to produce a pulse signal V1 indicative of each incremental movement of the beam (equivalent to one grid position) and a signal VS indicative of the sign (direction of the beam movement). The image light is directed to the recording medium RM via a polarizer PZ and a pair of Kerr cell type shutters KS1, KS2 which may be operated selectively and allow a greater width (vertical dimension of the RM as seen in Fig. 1) of the recording medium to be utilized.
