Overview

The ZETA Surface Conditioning System is a fully automated centrifugal spray processor designed for advanced, batch cleaning, etching and stripping applications on 200-mm and 300-mm wafers. The system is completely closed, providing greater process control and repeatability in an extremely clean environment. Compared to traditional wet cleaning technologies, the ZETA system uses less fab space and chemicals and operates at a much lower cost. It performs a variety of etching applications, including patterned aluminum etch/strip, wafer reclaim, oxide etch/strip, and polysilicon deglaze.
