Etch values are listed in Ang per min rate, using only a single wafer, resist values are for hard baked layers.
All values listed should be within 10% of those posted. These values are only a guide.
For more exact etch rates testing should be done by the user with the intended material.
* Means these recipes can have large varying etch values, test etch rate on a test sample first. 29-Jul-04
