* [[Photolithography - HMDS Process for Improving Adhesion|HMDS Process for Improving Adhesion]] - use this procedure if you are finding poor adhesion, or for chemcials (like BHF) that attack the PR adhesion interface strongly.
* [[Photolithography - Manual Edge-Bead Removal Techniques|Manual Edge-Bead Removal Techniques]] - removing the edge-bead from your substrate will help with contact litho resolution and alignment.
