Title: Semiconductor memory and manufacture thereof
Inventor: YOSHIHARA IKUO
IPC: H01L21/822
Filed: 1990-07-20
Abstract: PURPOSE:To realize high speed of a semiconductor memory, to improve resistance to a soft error caused by alpha line and to realize high integration density of a memory cell by forming at least one capacitor electrode through a dielectric film on an island-like single crystalline semiconductor layer side and by forming an access transistor in the island-like single crystalline semiconductor layer. CONSTITUTION:A dielectric isolation island-like single crystalline semiconductor layer 7 and a base 1 for holding it are provided, at least one capacitor electrode 3 is formed at the side of the island-like single crystalline semiconductor layer 7 between the base 1 and the island-like single crystalline semiconductor layer 7 through a dielectric film 5, and an access transistor is formed at the island-like single crystalline semiconductor layer 7. Thereby, high speed of a semiconductor memory can be realized. There is little effect to a charge stored node even if alpha line is injected, and resistance to a soft error caused by a line can be improved. Furthermore, since a structure formed by laminating an access transistor on a capacitor can be realized, an area a memory cell can be reduced. High integration density of a memory cell can be realized in this way.

IPC: C23C2/02
Filed: 1981-11-30
Abstract: PURPOSE:To improve the adhesion of hot dipping, by depositing Al of solid soln. in an aluminum killed steel plate by annealing at a prescribed rate of AlN deposition then dissolving away the same thereby obviating concn. of Al in the steel onto the surface layer of the steel plate in the stage of reduction by heating. CONSTITUTION:An aluminum killed steel plate contg. 0.02-0.07% acid soluble Al in steel is subjected to batch annealing to allow Al of solid soln. to deposit as AlN and to immobilize the same. The rate of deposition of the AlN (rate of deposition of AlN= content of N as AlN/content of total N in the steel) is set at >=90%. The surface of the steel plate is pickled to remove the concd. Al layer in the surface layer of the steel plate. Thereafter the steel plate is reduced by heating and is plated in a hot dipping line. Thus the plating layer of good adhesion is obtd.

When the level Vw of the word line Wb becomes higher than the threshold valuve, the constant current circuit Ics stops introducing of current Id, and the state of the word line Wb is changed at once to the plate of H by output current Is from an emitter follower. Thus, fall characteristic of the selection line is improved to increase speed of changing of the selection line, and access time can be made high speed.

Abstract: PURPOSE:To attain the high-speed follow-up to a periodical input signal having its frequency varying in the lapse of time, by constituting a frequency multiplier with an oscillator, a frequency divider, an up-counter, a register and a down- counter respectively. CONSTITUTION:A frequency multiplier is divided with an oscillator 10, a frequency divider 20, an up-counter 30, a register 40 and a down-counter 50. The frequency of a signal which receives the frequency multiplication is set at fs, and a division signal having a frequency fOS much higher than the frequency fs is added by a counter for a cycle period of the signal of the frequency fs. The count number M of that time point is subtracted a pulse having a frequency fOS. Thus the count number reaches zero in time DELTAt after the subtraction is started. If a pulse signal is obtained at the time DELTAt, the frequency of the obtained signal is set accurately at N.fs.

Abstract: PURPOSE:To obtain a magnetic rotary scale, which is highly accurate and has an arbitrary number of division, by controlling and rotating a magnetic medium disk at a reference frequency, and magnetically recording a magnetizing pattern having an arbitrary number of division by a signal based on the reference frequency. CONSTITUTION:A motor 3 is controlled so that it is rotated at a constant speed by a motor rotation control system 2 based on a signal of a reference frequency f0 that is taken out of an oscillator 1. A disk 4, which is formed by a magnetic medium, or on the surface of which a magnetic medium is formed, is attached to the motor 3. The motor is rotated at a constant number of rotation N. Meanwhile, an arbitrary frequency (f) is formed based on the frequency f0 by a divider 5. A magnetizing pattern is written on the disk 4 by a writing head 7 through a writing path 6. Thus a magnetic rotary scale is obtained. The magnetizing pattern is recorded in a broken line circumference, which is determined by the frequency (f) imparted by the divider 5 and the number of rotation N. Thus, the number of division of the magnetic rotary scale of the magnetic rotary encoder can be arbitrarily selected, and the number of division can be provided in a high density.
