Title: Semiconductor device
IPC: H01L27/144
Filed: 1974-09-20
Abstract: 1454322 Semiconductor devices AKADEMIE DER WISSENSCHAFTEN DER DDR 20 Sept 1974 [3 Oet 1973] 41045/74 Heading H1K A semiconductor device for light integration, e.g. for use in a target array of a t.v. camera, consists of a semiconductor body 1 containing deep traps, a first electrical contact 2 for injecting charge carriers which are captured by the traps and a second electrical contact 3, which may be capacitively coupled to the body 1 through a thin insulating layer 4 as shown, and which does not inject charge carriers. At the commencement of an integration period the application of the voltage pulse causes charge carriers, which may be of either majority or minority types, to be injected from contact 2 into body 1 where they become trapped. Absorption of light, either directly at the traps or elsewhere in the body, frees a proportion of the trapped charges so that, at the end of the integration period, they contribute to a measurement current pulse. The injecting contact 2 may be a metal-semiconductor contact or a P<SP>+</SP>-P or N<SP>+</SP>-N barrier. The deep trap may be ion inplanted inpurities or radiation-induced defects. Where the non-injecting contact 3 is capacitive as shown it may, in an array of such devices, form part of a charge-coupled shift register. A particular embodiment comprises a body 1 of N type 500 #cm. Si containing Au or Ag deep acceptors in excess of the donor concentration. The N<SP>+</SP> contact 2 is formed by P-diffusion to a degenerate level.

Filed: 1975-10-14
Abstract: 1511543 Data transmission; cyphering TELEFONAKTIEBOLAGET L M ERICSSON 14 Oct 1975 [17 Oct 1974] 42089/75 Heading H4P A circuit for a cyphering/decyphering system has n memories each having N memory fields each associated with a counter for scanning the fields to obtain key information to generate a cypher series, with N switch devices to determine from which memories information will be read, and a device to control operation of the switches by providing selection information. The memories may be electronic or different parts of an electronic memory, punched cards or tapes or different parts of a card or tape. Cycle length counters, e.g. R1 supply control signals to n data selectors, e.g. DS11-DS1n each of which is allocated to a memory so that one bit at a time is selected from a respective field, provided such field is enabled by selection switches Sl  (which may be stages of a shift register) controlled by a device SA responding to special character combinations KD inserted in a non cyphered message, which determine the selection of memory fields through switches S1; these switches may be incorporated in the data selectors. Control characters may be transmitted uncyphered, but key information determining starting position of counters is cyphered which resists breakage of the code. At the receiver, memory field selection is determined by the data transmitted to it.
