Title: Improvements in or relating to methods of producing semiconductors having alloyed p-n junctions
IPC: H01L21/322
Filed: 1959-12-02
Abstract: 934,937. Semi-conductor devices. TELEFUNKEN G.m.b.H. Dec. 1959 [Dec. 3, 1958], No. 40896/59. Drawings to Specification. Class 37. A method of producing a semi-conductor having an alloyed PN junction comprises forming said PN junction by alloying a substance to a surface of a semi-conductor material, which surface has lattice disturbances. The prior art of preparing sawn surfaces of semi-conductor material for alloying by treating with an abrasive material and subsequently treating with an etching material to remove lattice disturbances is referred to. The lattice disturbances are now present during the alloying process and prevent the alloying substance from spreading over the semi-conductor surface. The lattice disturbances preferably extend to a depth not greater than the depth of the alloyed layer constituting the PN junction and are preferably produced by sawing alone or by sawing and abrasion but may be produced by a further treatment. The omission of the etching treatment and in some cases the abrasion process prior to alloying results in a considerable saving of semi-conductor material. After the alloying process the remaining surface lattice disturbances and disturbances at the boundary of the alloyed layer are removed by etching, as hitherto.

Abstract: 1504248 Applying compressive pressure to limbs KENDALL CO 7 Oct 1976 [28 Oct 1975] 41795/76 Heading A5R A device for applying compressive pressure to a patient's limb comprises a sleeve 26 having a plurality of laterally extending chambers 48a, b, c, d, e and f, Fig. 3, and outlets (56), Fig. 2 (not shown) communicating with the individual chambers and connected to conduits 34a and 34b, and a controller for forming from a source of pressurised pneumatic fluid a timed sequence of periodic inflation cycles, each consisting of a plurality of pressure pulses, applying each of said pulses to a manifold, Fig. 7, and thence via the conduits 34a and 34b to separate chambers of the sleeve in such fashion that later pulses in the sequence are applied to more upwardly located chambers than earlier pulses to apply against the limb a compressive pressure gradient such that the applied pressure decreases from the lower to the upper portion of the limb, and subsequently connecting the chambers to exhaust via conduits 34a and 34b to provide periodic deflation cycles between the inflation cycles. Figs. 9 to 11 (not shown) depict pneumatic control circuits for producing three pressure pulses, each of which is split into two portions in the manifold and said portions applied to adjacent chambers of the sleeve. The first pressure pulse is applied to a conduit 28a, Fig. 7, of the manifold separated into two portions through orifices 66a and 66b and further separated through orifices 70a and 70b to conduits 34a and 34b which apply pressure to the first chambers 48a of sleeves 26, and through orifices 70c and 70d to further conduits 34a and 34b which apply pressure to the second chambers 48b. Since orifice 66a is larger than 66b, the rate of pressure increase in the chambers 48a is higher than in the chambers 48b. The manifold has similar sets of conduits for applying the second pressure pulse to chambers 48c and 48d and the third pressure pulse to chambers 48e and 48f. Each pressure pulse is formed from the preceding pulse so that the maximum pressure exerted by each pulse is lower than that exerted by the preceding pulse, and once the maximum pressure for each pulse has been reached, it is maintained until the end of the inflation cycle. The control circuit may include means for adjusting the interval between initiation of each pulse, the duration of the inflation cycles and the interval between successive inflation cycles.
