Dear All, I am a new-comer of MEMS area. I am suffering from KOH etching problem. My outside convex edge has been etched to be round because I forget corner compensation when I draw my design. I do not have any budget to order a new mask. Is KOH+IPA will help me? What is the recipe? I am also confused what the undercut compensation really meant in some literature. Your help is highly apperciated. Lydia ------------------------------------------------- This mail sent through IMP: http://horde.org/imp/
