Title: Inspection apparatus for wafer pattern
IPC: H04N7/18
Filed: 1992-04-02
Abstract: PURPOSE:To perform highly accurate pattern inspection without erroneous inspection caused by the dispersion in surface processing between wafers. CONSTITUTION:The inspected image of a wafer 1 is inputted from a visual sensor 3. The inputted inspected image is compared with a master image, which is stored beforehand, in an image comparing circuit 4d. The good or defective state of the wafer 1 is judged with a judging circuit 4e based on the amount of the difference between the compared images. When the amount of the difference is less than the specified value, the inputted inspected image is stored into a master memory circuit 4h as the new master image. The result of the judgment for the good or defective state of the wafer is outputted into a judged- output processing circuit 5. Even if the surface state of the wafer 1 is slightly changed, the master image is renewed in following the change. Therefore, the dispersion in the surface states are cancelled, and only the difference caused by the circuit defect and the like is excellently detected.

Title: Measuring method for insulation resistance
Inventor: MATSUNO TATSUJI
IPC: G01R27/02
Filed: 1981-07-13
Abstract: PURPOSE:To measure an insulation resistance independently of a phase shift by using three measurement signals having different phases in a method wherein a measurement signal is injected through the earthing line of a transformer and the insulation resistance is measured in the condition of a live wire. CONSTITUTION:A signal for measurement is injected into an earthing line EL through the intermediary of an oscillation transformer OT. The signal given a phase shift theta while passing through a aero-phase current transformer ZCT and a filter FIL is multiplied in a multiplier MULT by three kinds of voltages having prescribed phase differences theta1-theta3 from a voltage induced in an electric circuit and thereby the respective products are obtained. Thereafter, the respective DC parts of these products are found in a low-pass filter LPF. A value inversely proportional to an insulation resistance can be found from three values obtained in the filter by a prescribed arithmetical circuit AU. This value is entirely irrespectively of the phase shift theta obtained through ZCT and FIL, and thus complicated phase compensation circuit is unnecessitated.

IPC: H03K17/687
Filed: 1994-05-24
Abstract: PURPOSE:To obtain an output circuit of the semiconductor equipment extracting the output signal of the same duty factor as that of an input signal. CONSTITUTION:An input signal is inverted by an inverter 21 to drive an n- channel MOS transistor(TR) 23 of a pull-up side of a driver, the output of the inverter 21 is inverted by an inverter 22 to drive an n-channel MOS TR 24 at pull-down side. Then a drive signal is outputted from a connecting point between the n-channel MOS TRs 23, 24 connected in series to drive an output TR 25. Since the gate voltage of the output TR 25 is raised only by a voltage resulting from subtracting a threshold voltage from a power supply Vdd, rising time and trailing time of a gate potential are reduced to improve the duty ratio.

Abstract: PROBLEM TO BE SOLVED: To obtain a gel having many micropores by applying an aqueous dispersion of fine particles on a support to form a layer of the dispersion, agglomerating the fine particles by destabilizing the dispersion before the water is completely evaporated, and drying the layer. SOLUTION: Water and a specified amount of a nonionic emulsifier are fed into a reactor and heated.
