Title: Semiconductor device and fabrication thereof
Inventor: USHIYAMA MASAHIRO
IPC: H01L27/115
Filed: 1998-11-20
Abstract: PROBLEM TO BE SOLVED: To suppress diffusion of phosphorus from the floating gate electrode of a flash memory by introducing both oxygen and nitrogen into a polisilicon film thereby suppressing diffusion of boron from a P+ gate electrode. SOLUTION: After an insulation film 32 for isolating element is formed on the surface of a silicon substrate 31, a pyrogenic oxidation silicon film is formed on the silicon substrate 31 followed by formation of a gate insulating film 34. Subsequently, a mixture gas of monosilane and nitrogen monoxide is fed to deposit a silicon film. Boron ions are then implanted into the silicon film to form a gate electrode 35. Consequently, diffusion of dopant in the polysilicon film to the gate insulating film 34 can be suppressed and charge holding characteristics of a nonvolatile semiconductor memory can be enhanced. Furthermore, a device where fluctuation of the threshold voltage is suppressed can be obtained because diffusion of boron can be suppressed.

IPC: G11B20/10
Filed: 1988-12-28
Abstract: PURPOSE:To prevent the transformation of data due to a fact that a data block is skipped over even in the case the recognition of a mark is impossible by confirming the detection of the data block based on the recognition of the mark as well as the presence or absence of a synchronizing code. CONSTITUTION:A mark identifying circuit 7 identifies a mark (a) which shows the start position of the data within a data block and sends the recognizing result of the mark (a) to a block recognizing circuit 8 via a signal line 108. The circuit 8 decides the presence or absence of the data block based on the presence or absence of the mark (a) as well as an intra-data block synchronizing code detecting signal received from a read data demodulating circuit 2B via a signal line 109. Thus it is possible to prevent the transformation of data caused by a skipping action of the data block even in the case the recognition of the mark (a) is impossible on a magnetic tape.

Abstract: PROBLEM TO BE SOLVED: To prevent an overvoltage from being transmitted to a communication equipment in the latter stage by arranging a voltage nonlinear material between the central conductor of a coaxial connector and an external conductor, and operating the voltage nonlinear material even when the overvoltage is inputted to the connector. SOLUTION: An annular or concentric cylindrical voltage nonlinear material 6 is integrated into part of an insulator 3 filled between the central conductor 1 of a coaxial connector and an external conductor. As the voltage nonlinear material 6, a varister easy to mold, or a semiconductor element such as Zener diode, PNPN element or the like is used. When the voltage between the central conductor 1 and the external conductor exceeds a prescribed value in an input terminal 4, the voltage nonlinear material 6 is operated to suppress the voltage of an output terminal 5 to a prescribed voltage or less. Thus, no overvoltage is inputted to a communication equipment connected to the output terminal 5, and the communication equipment can be protected from overvoltage.
