Title: Semiconductor integrated circuit
Inventor: KOBAYASHI TOMOKO
IPC: G11C29/04
Filed: 1989-09-28
Abstract: PURPOSE:To enable the initialization of the node within a chip so as to prevent the generation of abnormal currents by generating a signal which has pulse width enough for all the nodes within the chip to be initialized until the output signal of a power source voltage detecting circuit becomes low level from high level after power up; and operating a control circuit for the node within the chip regardless of the level of an external input signal. CONSTITUTION:While an output signal PON is at high level, MOSFETs Q1 and Q2 become OFF and MOSFETs Q3 and Q4 become ON, and an external input from RAS is cut, so a RAS system control circuit 2 operates by the output of a one shot pulse generating circuit 3. The one shot pulse generating circuit 3 outputs, to a node N2, a signal of pulse width enough for initializing of the RAS system control circuit 2 and initializing all the nodes N1-N7 within a chip by making use of the delay time from the point of time when the output signal PON makes a transition from high level to low level to the point of time when the node N changes from low level to high level. Since the RAS system control circuit 2 operates most of the nodes within the chip, the whole chip can be initialized enough only by inputting a clock into the RAS system control circuit 2.

Abstract: PROBLEM TO BE SOLVED: To stably extract edge information of an image pattern irrelevantly to variation of color information of the image pattern and wavelength limitation of illumination light by making lights from slightly shifted position on a body to be inspected to interfere with each other. SOLUTION: The illumination light emitted by a light source 7 after being passed through a condenser lens 9 is converted into a specific linear polarized state by passing through a polarizer 21 and further Wollaston prism 22. The (p) wave and (s) wave take two optical paths which are parallel to each other and shifted by a fine quantity when separated to light up the body 1 to be detected respectively through an objective lens 3. The reflected lights of the two illumination lights after passing through the objective lens 3 again pass through the Wollaston prism 22 in the opposite directions from their going ways, so that the illumination lights which have shifted in parallel are put together into a coaxial optical path.  The composed light after passing through an optical path change mirror 6 is made incident on an analyzer 23, which causes the two reflected lights to interfere with each other.
