=== Process A ===
Process A is labelled ''Large trench (80μm wide) 150μm depth''. In the acceptance test the process was run on a 150 mm SPTS wafer with 12-13 % etch load.

=== Process B ===
Process A is labelled ''Via (30μm diameter) 100μm depth''. In the acceptance test the process was run on a 150 mm SPTS wafer with 12-13 % etch load.

=== Process C ===
Process A is labelled ''Nano silicon etch''. In the acceptance test the process was run on a 100 mm Danchip wafer with a test pattern of a series of lines and dots with sizes ranging from 30 nm to 300 nm. The etch load was extremely high, approaching 100 %.

=== Process D ===
Process D is labelled ''Micro stamp etch''.
In the acceptance test the process was run on a 100 mm wafer with 50 % etch load.

=== SOI etch ===


The SOI etch uses the Low frequency (LF) platen generator to minimize the notching at buried stop layers such as the BOX layer in a SOI wafer.
