Title: Semiconductor translating devices and processes for making them
IPC: H01L29/06
Filed: 1959-08-04
Abstract: 922,617. Semi-conductor devices. WESTERN ELECTRIC CO. Inc. Aug. 4, 1959 [Aug. 13, 1958], No. 26560/59. Class 37. In a semi-conductor device comprising a monocrystalline silicon body having N- and P-type regions separated by a planar PN junction the P and N regions are substantially uniformly doped with gold or platinum to reduce the minority carrier lifetime therein and hence the reverse recovery time of the junction. In one embodiment boron is diffused into both faces of an N- type silicon slice by heating in a boron containing gas, or by precoating with a solution of boricanhydride in ethylene glycol monomethyl ether and heating in air to 1230 C. for 16 hours. After removing one of the P-type layers thus formed the exposed N-type surface is coated with a solution of phosphorus pentoxide and heated for 2 hours at 1100 C. in air. Subsequently both faces are coated with gold and the slice heated in nitrogen at 1100 C. for an hour to effect complete solid solubility of the gold throughout the body. The concentration of gold is determined by the solid solubility and hence by the temperature of the diffusion. The P-type layer is largely removed ultrasonically to leave isolated islands of P-type and the plate cut ultrasonically into circular discs each including one such island (Fig. 2). Gold electrodes are finally plated on the P- and lower N-type surfaces of the discs to form diodes which may be encapsulated in known manner as shown in Fig. 3. In an alternative method both faces of the slice are first coated with gold, and boron and phosphorus containing layers applied over the gold on the upper and lower surfaces respectively. The slice is then heated in inert gas for 12 hours at 1250 C. to distribute the gold simultaneously and provide the PN junction. The preferred concentration of gold in the finished devices is from 10<SP>15</SP> to 10<SP>17</SP> atoms/cc. Specifications 782,662, 809,644 and U.S.A. Specification 2,758,787 are referred to.

Abstract: 1327710 Semi-conductor devices COMPAGNIE GENERALE D'ELECTRICITE 19 April 1971 [13 April 1970] 26699/71 Heading H1K A thin semi-conductor device on an integral support, i.e. one in which the active regions have a combined thickness of less than 80 Á, forming a diode, transistor or thyristor is produced in a thyristor embodiment as follows: a silicon substrate 16 of P type and at least 300 Á thickness has an N type region 2 diffused into one face, which face is then covered by semiconductor material 18 of N type forming a support of at least 300 Á thickness, the material 18 being deposited by a low temperature epitaxial process; the other face of the substrate 16 is then abraded (to X) until the substrate is reduced to about 30 Á, and a further N type region diffused into the abraded face, followed by a smaller P type diffusion so as to form the thyristor structure. The epitaxial process is carried out at 750‹ C. in the presence of hydrogen at atmospheric pressure and a Si 2 Cl 6  vapour under ultra-violet light. The material 18 may be of silicon or a layer of silicon carbide between layers of silicon.  Alternatively a "snap-off" diode may be constructed from an intrinsic silicon substrate by forming an N type region in one face followed by a low temperature epitaxial deposition of N type semi-conductor material. The other face of the substrate is then abraded down to a suitable thickness and the remaining substrate doped with a P type impurity to form a P-N junction. The use of an epitaxial deposited support at deposition temperatures which have little effect on impurity distribution within the substrate, prior to the removal of most of the substrate prevents breakage of the wafer during processing.

Abstract: 338,997. Holmes & Co., Ltd., J. H., Miller, R. B., and Robertson, A. T. Sept. 4, 1929. Feeding webs.- In a web-renewing mechanism f o r printing or other machines, the rotation of the new roll about its own axis before it is brought into contact with the old web is effected automatically by the movement of the roll-carrying frame or a part of its driving mechanism during the translation of the new roll to the joining position. In one form, Fig. 1, the rotation of the roll-carrying frame B closes a clutch to cause the rotation of driving discs J<1> engaging the surface of the new roll A<1>. The discs J<1> are carried by a frame H pivoted on a shaft E driven by gearing from the printing &c. machine and are driven from a chain-wheel F normally loose upon the shaft E but adapted to be clutched thereto, by the partial turning of a shaft K when a cam L on the gear wheel B' driving the frame B engages with a roller M<3> on an arm M' on the shaft K. The arm M' is loose upon the shaft K and is of right-angled form, one arm carrying the roller M<3> and the other engaging between a pair of screws M<5> carried by lugs on a hand lever M<4> fixed to the shaft K. The screws M<5> permit of a slight adjustment of the arm M<1> relatively to the shaft K and the handlever permits operation of the clutch independently of the cam L if desired. Instead of a mechanical clutch an electromagnetic clutch controlled by the roll-carrying frame may be employed. In another form, the discs J<1> are driven by chain gearing from a shaft carrying a pinion gearing with the wheel B<1>, and in a third form, the axle of the new roll is provided with a pinion adapted to engage a stationary but preferably spring-supported rack during its movement of translation to the joining position.
