Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To extend a frequency characteristic on the side of high frequency and to improve losses and distortion characteristics in a wide range by connecting 2nd capacitors in parallel with a capacity that is smaller than that of 1st capacitors to the 1st capacitors, which make the anode and cathode of diodes connected serially at the same potential with respect to high frequency. SOLUTION: Both ends on the side of an output of a transformer are separately connected to a connecting end Pa of the anode of a diode D1 and the cathode of a diode D2 which are connected in reverse directions and to a connecting end Pb of the cathode of a diode D3 and a diode D4 which are connected in reverse directions. A capacitor C1 is connected between the cathode of the diode D1 and the anode of the diode D3, and a capacitor C3 is also connected between the anode of the diode D2 and the cathode of the diode D4.

Title: Surface treatment of substrate
Inventor: YOSHIDA KOZO
IPC: H01L21/30
Filed: 1988-06-25
Abstract: PURPOSE:To uniformly and rapidly surface-treat a substrate by the inertia force of a processing soln. layer by forming the processing soln. layer on the surface of the traveling substrate, and reciprocating the substrate in the horizontal direction. CONSTITUTION:The substrate W is placed on a conveyor roller R1, and conveyed. The processing soln. from a processing soln supply means 12 is supplied in the form of a curtain by the signal from a detecting sensor S1 to form the soln. layer 10 on the surface of the substrate W. When the substrate W passes directly below a sensor S2, the substrate W is transferred onto a conveyor roller R2 and horizontally traveled at low speed. When the substrate W is traveled by the distance D1 and reaches directly below a sensor S3' the roller R2 is rotated in the opposite direction to travel the substrate W toward the sensor S2. When the substrate W comes to the position of the sensor S2, the roller R2 is rotated in the normal direction. Meantime, the processing soln. is agitated by the inertia force of the soln. layer 10 formed on the substrate W, and the processing soln. in contact with the surface of the substrate W is refreshed. In addition, the surface treatment is rapidly carried out by the interaction between the inertia force of the soln. layer 10 and the movement of the substrate W in the opposite direction.
