Patent JP-S62122263-A (JP)
Title: Semiconductor integrated circuit device
Inventor: MIYAZAKI YUKIO
IPC: H01L27/088
Filed: 1985-11-22
Abstract: PURPOSE:To increase a mirror capacitance and to decrease noises generated in power source lines or GND lines at the time of switching, by increasing the overlapped area of the gate electrode and the drain diffused part of a p- or n-channel MOS transistor, which is connected to a power source and GND and constitutes an output circuit. CONSTITUTION:The overlapped part of the diffused part of a drain 13 and a gate 14 of an output transistor 11 at p- or n-channel MOS transistor 22 and 23 constituting an output circuit is large. A mirror capacitance 18 is larger than a mirror capacitance 8. Therefore the waveform at the input stage of the output circuit can be made gentle. Charge and discharge of a capacitor at an output terminal are controlled, and electromotive forces generated in inductances 110-112 can be suppressed. Owing to the suppression of the electromotive forces, noises generated at GND 114 can be reduced. Similarly, an electromotive force generated in parasitic inductance of a power source lines 113 can be suppressed, and the noises generated can be reduced. The diffusing depths of the p- and n-channel transistors 22 and 23 are made deeper than an inner transistor 1, and the mirror capacitance at the output circuit can be increased.

Title: Function visualizing apparatus
Inventor: TOIDA MASAHIRO
IPC: G01N21/39
Filed: 1988-10-20
Abstract: PURPOSE:To visualize functioning state of a sample by measuring lasers passing through each point of said sample by a photoelectric detector and composing an image from differential data of outputs of an optical heterodyne detection by a light having a wavelength not absorbed by an object to be detected in said sample and a light having a wavelength absorbed by said object and, positional data of measuring points. CONSTITUTION:A laser light L1 from a laser unit 1 is divided into two. A frequency of one of the divided light L1(L2) is deflected, and the light L1(L2) is converged and radiated to a sample 7 through a lens 10. Transmitting lights L1B, L2B of the light L1(L2) are mixed with the light L2(L1) and detected by a photoelectric elector 11 as an optical heterodyne detection wave. Then, only the deflecting components of the frequency are selected and accordingly a signal light can be detected with the sensitivity of quantum limit of the photoelectric detector 11. Therefore, the change of the signal light can be detected with high sensitivity. The above detecting process is performed for every point of the sample 7. Thus, the sample can be visualized by the radiating position and the optical heterodyne detection outputs when said sample is detected. The functioning state of the sample can be thus visualized.

The alignment is made with seeing the interference of the flat surface Fizeau lens 2 and the perforated flat plate 4 of the null lens 3. It is made with observing the interference of a light emitted from the interferometer 1 and reflected on a reference surface 23 with a light reflected on a reference reflection surface 25 of the flat plate 4.  The optical axes of the lenses 2 and 3 coincide on the order of the wavelength and as the result the optical axes of the interferometer 1 and the lens 3 coincide.
