Title: Electroplating equipment
Inventor: MORI ATSUSHI
IPC: C25D21/00
Filed: 1990-05-25
Abstract: PURPOSE:To simplify the structure and also to minimize the electric resistance of a power supply line to a work W even in an equipment for performing plating treatment in the corrosive atmosphere, and sufficiently enhance power supply efficiency by utilizing a pair of chucks to perform power supply to the work and also rocking the work. CONSTITUTION:In the case of performing plating treatment, the chucks 142 strongly catch an arm 21 by utilizing the force of a cylinder 136. Therefore, although electric resistance is made easily large in a contact part in a treatment chamber 3 filled with the vapor of plating liquid, the electric resistance between the chucks 142 and the arm 21 is minimized. Current is allowed to efficiently flow between a power supply rod 150 and the arm 21. During this treating operation, a cylinder 131 is positioned in a state wherein a rod 132 is intactly projected. Accordingly, a frame 130, a frame 135 and the power supply rod 150 are made to a state wherein these are integrally fixed. A jig J and a work W are rocked in the lateral direction X by actuating a motor 160 as above- mentioned in this state and rocking the frame 130. Thereby contact efficiency of the work W and the plating liquid is enhanced.

Abstract: PURPOSE:To reduce a threshold value current, to eliminate an astigmatism, and to eliminate a high order lateral mode by providing a stripelike groove to become a current passage, forming a multilayer crystal along the groove, and further forming diffusion blocking layers at both sides. CONSTITUTION:An N-type GaAs current blocking layer 2 is formed on a P-type GaAs substrate 1. A V-shaped groove 10 is formed at the center of the layer 2.
