摘要:
本发明公开了一种电镀用屏蔽装置,包括:阴极屏蔽板和阳极屏蔽板,阴极屏蔽板和阳极屏蔽板间隔设置,阳极屏蔽板上设有若干第一通孔,阴极屏蔽板上设有若干第二通孔,所述第一通孔与所述第二通孔相对设置,使得电力线可自所述第一通孔穿过并穿过所述第二通孔。本发明能够控制电力线的走向,提高晶圆电镀的效率。
摘要(英):
The invention discloses a shielding device for electroplating. The shielding device comprises a cathode shielding plate and an anode shielding plate which are arranged in a spaced manner, the anode shielding plate is provided with a plurality of first through holes, the cathode shielding plate is provided with a plurality of second through holes, the first through holes and the second through holes are arranged relatively, and thus power lines can penetrate the first through holes and then penetrate the second through holes. According to the shielding device, the directions of the power linescan be controlled, and the efficiency of wafer electroplating is improved.
