Patent JP-H02310391-A (JP)
Title: Ni-fe plating method
Inventor: OHASHI HIROYUKI
IPC: G11B5/31
Filed: 1989-05-22
Abstract: PURPOSE:To reduce a change of the compsn. of a plating film in the thickness direction by increasing the flow rate of a plating soln. on the surface of a material to be plated as the cathode with the lapse of time when the material is electroplated with an Ni-Fe alloy. CONSTITUTION:When an Ni-Fe alloy plating film is formed on a body to be plated as the cathode by electroplating, Fe as a baser metal than Ni deposits preferentially and the ratio between Fe and Ni in the plating film changes in the thickness direction. ln order to prevent this change, the flow rate of a plating soln. on the surface of the cathode is increased by gradually increasing the stirring rate of the plating soln., e.g., from 0.3Hz at the beginning of plating to 0.8Hz at the end of plating in the case of an Ni-Fe alloy plating film of 3mum thickness. A plating film having a nearly uniform compsn. in the thickness direction is formed.

Title: Thin plate carrying device
Inventor: MURAKAMI EIICHI
IPC: B65H7/04
Filed: 1990-05-21
Abstract: PURPOSE:To enable a thin plate to be accurately detected even if the thin plate is tilted in a carrier by a method wherein a detection beam is tilted to the thin plate. CONSTITUTION:A beam source is previously arranged so as to enable a beam to impinge on the surface of a thin plate 1 forming a certain incident angle with the thin plate 1. For instance, when a beam L is tilted by an angle larger than the angle of inclination + or -alpha of a wafer, the P side edge (hand takeout- intake side) is detected without fail, and moreover the beam L is prevented from being reflected from the underside of the wafer, and even if the beam L is reflected by the upside of the wafer 1, it is shut off by a pinhole 6b as it travels in a direction tilted by an angle of theta+ or -2alpha, Therefore, either the upside or the underside of the thin plate 1 can be detected, so that the accurate height of the thin plate 1 can be detected eliminating the light reflected from the surface of the thin plate 1. By this setup, the mis-detection of the presence and the height of the thin plate can be prevented when the thin plate 1 is tilted inside a carrier.
