Abstract:
1. A system for avoiding formation of gas bubbles on a selected region of a surface of a workpiece in a process chamber as the workpiece surface is brought in contact with a process solution for an electrochemical process using the process solution, comprising: a workpiece carrier to hold and move the workpiece; and a solution shaper having at least one high flow section to direct a process solution flow towards the selected region of the workpiece surface for a predetermined time, the solution shaper being adapted to move to bring the high flow section under the selected region of the workpiece surface, the solution shaper comprising a first shaping member and a second shaping member, wherein the shaping members are plates that are moved towards each other to form the high flow section under the selected region of the workpiece.
