              | Process characteristics: | 
            
            | Aspect ratio Specify preferred aspect ratio (if known) of etch process. Aspect ratio is defined as (etch depth)/(undercut).  | 
             | 
            
            | Depth Depth to etch in material.
   | 
             | 
            
            | Etching source gases Specify preferred source gases for the etch process (if known).  | 
             | 
            
            | Material Material to be etched.

             | 
            
            | Minimum feature size (masked) The dimension of the smallest masked feature to be protected during the etch.
   | 
             | 
            
            | Minimum feature size (open) The dimension of the smallest unmasked (open) feature to be etched.
