Title: Semiconductor device with built-in eprom
Inventor: MURANAKA KIYOHIKO
IPC: H01L29/792
Filed: 1990-07-19
Abstract: PURPOSE:To relax a stress to a pellet surface caused by a thermal stress by applying a polyimide film excepting an upper part of a gate electrode of a memory transistor (EPROM element) to form a passivation film. CONSTITUTION:A passivation film is composed of a silicon nitride film 9 covering a semiconductor chip surface and a polyimide film 10. The silicon nitride film 9 prevents a direct contact between a polyimide film 10 and an aluminum wiring 7. Although the polyimide film has good evenness, it is opaque to ultraviolet rays. However, since a window 11 is provided above a floating gate electrode 3, it is possible to carry out writing in a wafer state and erasing after characteristics check. It is not necessary to provide the window 11 to each EPROM element and one can be provided to an entire of the EPROM part. Anyway, it is only required to apply a polyimide film all over and to form a window thereafter by selectively removing it by photolithography technique.

Title: Semiconductor circuit
Inventor: JINRIYOU TAKAO
IPC: G06F3/00
Filed: 1989-07-24
Abstract: PURPOSE:To prevent a state where the noise signal is outputted from an output terminal and to prevent the malfunction of an external device by separating the output terminal from a common power supply and a Gnd in a period when the output signal of an output buffer is changed. CONSTITUTION:The output terminals 8 - 10 change at one time when 1st input signals 3 - 5 change. A 3rd input signal 7 turns off an N channel MOSTR 18 and a p channel MOSTR 17 in a period when the outputs of the terminals 8 - 10 are changed. Therefore the output of an output buffer 15 is separated from an output terminal 11 in a period when the output signals of the output buffers 12 - 14 connected to the same power supply and the same Gnd are changed simultaneously. Thus it is possible prevent such a state where the noise signals produced via the power supply and the Gnd at the change of the output of buffers 12 - 14 are outputted via the terminal 11.

Filed: 1985-08-30
Abstract: PURPOSE:To obtain such light distribution characteristic as wide in the longitudinal direction of lamp by arranging a louver comprising a plurality of conical rings at the position surrounding a light emitting tube. CONSTITUTION:A louver 9 comprising a plurality of conical rings is arranged at the position surrounding a light emitting tube.
