Filed: 1999-08-04
Abstract: PROBLEM TO BE SOLVED: To always remove phosphorus from treating water with high removal efficiency without necessitating a periodical maintenance and control work. SOLUTION: The treating water 18 flows in a water tank 20 and a motor 28 is driven, then an agitation blade 26 is rotated and a blade part 2606 rotates above a bottom plate 22.

Abstract: PURPOSE:To form a conductor wiring layer uniformly through electroplating by forming a longitudinal groove along the outer circumference of some substrate at a portion of a basic substrate for forming a fine multi-wiring layer other than the wiring region at the circuit face side of the substrate then depositing an electroplating layer, as a cathode ring, on the side face and the bottom face of the longitudinal groove. CONSTITUTION:A longitudinal groove 2 is formed along the outer circumference of some substrate 1 at other than the wiring region at the circuit face side of the basic substrate 1 for forming a fine multi-wiring layer. For example, the substrate 1 is formed of alumina ceramics and the longitudinal groove 2 is formed along the outer circumference of the substrate 1 at the outside of the pattern region 5 on the surface (circuit face side). A cathode ring pattern 4 is formed on the side wall and the bottom face of the longitudinal groove 2, and electroplating is carried out simultaneously with deposition of a conductor wiring layer 3 through electroplating. Since wider area is available for formation of the cathode ring when compared with the case where the cathode ring is formed on a plane, the effect of the cathode ring pattern for uniforming the thickness of electroplating of the conductor wiring layer 3 can be improved.
