Patent ID: 6860964

Claim:
An apparatus for processing a substrate, the apparatus being formed by combining etching and stripping equipment with cleaning equipment, the etching and cleaning equipment being comprised of modules joined end to end to form a unified structure, wherein the substrate is moved directly out of one of the modules into another one of the modules in succession, the unified structure comprising: an etching line comprising an etch module joined end to end with a rinse module for etching and rinsing the substrate prior to stripping; a stripping line for stripping the substrate, the stripping line being connected to the etching line; a transfer module having an end thereof directly joined to an end of the etching line and an end thereof directly joined to the stripping line, for moving the substrate from the etching line to the stripping line with no exposure of the substrate to the outside of said unified structure; a cleaning line installed on the stripping line to clean and dry the substrate; and an elevator for conveying the substrate from the stripping line to the cleaning line, wherein, the unified structure is sequentially arranged in the order the etching line, the transfer module, the stripping line, the elevator and the cleaning line.
