Title: Semiconductor device and method of fabricating the same
Inventor: NAKANISHI KENTARO
IPC: H01L29/78
Filed: 1996-05-24
Abstract: PROBLEM TO BE SOLVED: To provide a high-performance and very reliable MOS semiconductor device. SOLUTION: On a silicon substrate 1 in which element separating regions 2 are formed, a gate oxide film 3 and a polysilicon film 4 are sequentially deposited and a gate electrode is patterned in a predetermined position by using a dry etching technique. First, impurities are ion implanted, thereby forming a first impurity diffusion layer 8. By ion implanting second impurities, a second impurity diffusion layer 9 having the concentration higher than that of the first impurity diffusion layer 8 is formed. Third impurities of an conductivity type inverse to those of the first and second impurities are counter-doped, thereby forming a third impurity diffusion layer 10 of the same conductive type as those of the first and second impurity diffusion layers, having the concentration lower than that of the second impurity diffusion layer.  Subsequently, side walls 6 are formed by using an etchback method. Finally, by ion implanting fourth impurities, a source-drain diffusion layer 11 is formed, thereby completing a semiconductor device.

Abstract: PURPOSE:To enhance the durability of a water drop removing device, whereby water drops attached to a plate-shaped member of a car vision mirror are removed through vibration of a vibrator mounted on the plate-shaped member, by reducing the supplied power when the power to the vibrator has exceeded a certain value. CONSTITUTION:A piezo vibrator 20 affixed to a part of a car vision mirror is fed with electric power through a driver circuit 451 during a certain period of time specified by a timer circuit at the time of a switch being turned on, and is vibrated to remove water drops attached to the mirror surface. This driver circuit 451 is furnished with an oscillator circuit 51 and an overcurrent sensing circuit 53, the latter to sense the size of the energization current flowing through the primary side of a booster transformer 59 in the form of a voltage over the ends of a resistance R1 to determine the overcurrent through comparison of this sensed voltage with the reference voltage. When an over current is sensed, the output of a one-shot multivibrator 52 is inverted, and FETs 55, 56 are turned off through NOR gates 57, 58, and thus current supply to the piezo vibrator 20 is stopped.

Meanwhile the electric signal obtained by applying the photoelectric conversion to the laser beam received through the line 61 via the diode 641 is amplified by an operational amplifier 691 of an amplifying part 651. Then the amplifier 691 outputs a reception signal. Under such conditions, an inductor 11 which is placed between the diode 641 and the amplifier 691 after setting the value by a prescribed expression compensates the junction capacity CS of the diode 641 and then applies the peaking to the part 651.
