IPC: H03M11/04
Filed: 1979-10-27
Abstract: An encipher-decipher apparatus including an input keyboard and a processing and control stage which enciphers or deciphers data received directly from the keyboard or preferably from a text store with the aid of a cipher generator. The cipher generator produces a cipher sequence dependent on two code data items that determine the initial state of the cipher generator. One item for encryption is supplied as a set of random code characters from a random generator. The random generator comprises a continually cycled modulo-n counter and a FIFO memory into which the instantaneous state of the counter is entered at each of successive actuations of keys of the keyboard, such key operations being those done in any event in the use of the apparatus. The cycle time of the counter is much less than the time between consecutive key operations. A clock rate of 100 kHz is suggested. The set of characters is read out of the FIFO store at the start of data processing for use by the cipher generator.

Title: Nonvolatile semiconductor memory device
Inventor: SATOU NOBORU
IPC: H01L21/8246
Filed: 1978-11-13
Abstract: PURPOSE:To make write and erase feasible at low voltage and also to prolong memory retention period by forming tungsten oxide  in molecularity on the interface of SiO2 film and Si3N4 film. CONSTITUTION:Tungsten oxide is chiefly WO2 or WO or a mixture thereof. These are distributed on the interface of SiO2 film 4 and Si3N4 film 5 at 8X10<14>-2X10<16> atoms/cm<3> or so. Tungsten oxide is strong in bonding strength with the films 4, 5, and from raising temperatures of an Si substrate 1 up to 780-820 deg.C at forming the Si3N4 film 5, a better crystallinity is obtainable for SiO2 film 4. A resistivity of the Si3N4 film is thus improved, a stored charge is prevented from leaking to the gate terminal side, thereby prolonging a memory retention period. Further the discharge injected from the substrate 1 is caught at a large unit of the interface of the films 4, 5 and thus prevented from being distributed in the film 5. Write or erase efficiency is therefore improved and a low-voltage high-speed operation is secured.

Abstract: PURPOSE:To alleviate a thermal stress generated in a field-effect transistor(FET) having a PHS structure due to a difference of thermal expansion coefficients of a semiconductor substrate and a gold-plated layer when the FET is heated and to reduce warpage of the FET by providing grooves on the gold-plated layer of a rear surface of the substrate of the FET. CONSTITUTION:A gold-plated layer 14 of a semiconductor rear surface metal is provided in close contact with one main surface of a semiconductor substrate 101, and grooves 15 are formed on the layer 14. Warpage of a semiconductor device due to a temperature change is proportional to a size of the device, and displaced in a direction of elongating the layer to a GaAs substrate due to a difference of thermal expansion coefficients. Thus, when the device is heated and its temperature is changed, a thermal stress of the layer 14 is alleviated by the provided grooves 15, and warpage of the device due to a magnitude of the stress is reduced. Accordingly, a crack, a craze due to the warpage of the device are largely deleted, and a decrease in yield of an FET having a large size of the device can be prevented.
