Abstract: 1414126 Computer security arrangements KEY TRONIC Ltd 20 Feb 1973 [22 Nov 1971] 54174/71 Heading G4A Authorized users of a computer system are provided with a key which includes at least one random access "permanent" memory capable of retaining data when no power is supplied thereto, the computer system being arranged to allow access to information stored therein only after identification of the data derived from a key placed in communication with the system. Key encoding.-At specified intervals, e.g. every 48 hours, the user is required to insert his key in a socket provided at the main frame of the computer system. The computer system is programmed to erase previous data stored in the key, e.g. using ultraviolet radiation if the key memory is of MOS-LSI type, erase the storage keys held in a computer memory 14 and then store data randomly generated in the computer in the key 17 and memory 14 at addresses randomly generated by a unit 12. Key identification.-On insertion of a key in a request socket, which may be in a data terminal remote from the computer main frame, the computer causes simultaneous read-out of corresponding addresses (generated randomly by unit 12) in the key 17 and memory 14 for comparison at 53. The comparator 53 is arranged to enable access to storage 60 from the terminal on correct comparison being obtained, but inhibits further operation of the terminal, the actuation of alarms, and possibly also the automatic locking of the room in which the terminal is located, if an incorrect comparison is detected. The comparator may include a counter providing the OPEN signal on reaching a count indicating that the data stored at all addresses of the key 17 correspond to those stored in memory 14. If users are classified into groups having authorized access to different sections of storage 60, memory 14 is provided with key storage for each separate group and the ALARM signal from comparator 53 is inhibited until all key storage has been examined without correct correspondence between the key data and any one key storage. It may be necessary to insert a plurality of correct keys which are physically different and may store different data into complementary sockets before access to storage 60 is allowed.

Title: Metal-Semiconductor Barrier Devices
IPC: H01L23/485
Filed: 1966-12-16
Abstract: 1,169,726. Semi-conductor devices. TEXAS INSTRUMENTS Inc. 16 Dec., 1966 [6 Jan., 1966], No. 56448/66. Heading H1K. A rectifying contact is made between a metal electrode 17 and a relatively low impurityconcentration zone 18 of a single conductivitytype monocrystalline semiconducting region provided in the surface of a high-resistivity dielectric substrate 10. An ohmic contact is provided between a second metal electrode and a high impurity-concentration zone of the same semi-conducting region. In the embodiment shown the substrate 10 is formed of highresistivity Si, with the low impurity-concentration zone 18 being produced therein by phosphorus diffusion through an oxide mask 11. Two spaced high-impurity concentration zones 24, 25 are diffused on either side of the zone 18, and electrodes 17, 20, 21 are provided by evaporation or sputtering of Mo followed by sputtering of Au. The electrode 17 forms a rectifying contact while the electrodes 20, 21 form ohmic contacts, the difference being due to the different impurity concentrations in the respective zones. A further metal layer 15 of Au, Al or Mo and Au is deposited on the back of the substrate 10, and forms a ground plane for a microstrip transmission line constituted by the metal electrodes 17, 20/21 and the dielectric substrate 10. In a microwave mixer circuit described in the Specification two rectifying-barrier diodes are formed in the same substrate. Other devices such as transistors, resistors, and inductors may also be integrated with a diode according to the invention. The high- and low-impurity concentration zones may both be formed in a single diffusion step, due to the lateral diffusion which occurs under an oxide mask defining the area of the high concentration zone. A contact made through an aperture formed in the mask above a peripheral portion (49), Fig. 9 (not shown), of the diffused region will encounter relatively low impurity-concentration material and will be rectifying, while a contact applied to the central portion (47) of the region will be ohmic. In an alternative manufacturing method the active zones are formed by epitaxial deposition of material into shallow recesses etched in the substrate through a Si 3 N 4  mask. In this method a relatively high impurity-concentration layer may first be deposited, followed by a lower concentration layer. Both active and dielectric parts of the structure may be of GaAs, the substrate containing Fe or Cr deep level impurities, and combinations of Ge with a semi-insulating GaAs substrate or Si with a semi-insulating GaP substrate are also referred to. The substrate may also be of polycrystalline, ceramic or epoxy material deposited over mesas formed on a monocrystalline wafer, the wafer then being lapped away to leave only the spaced mesa portions supported by the substrate.
