AZ 15nXT Series Photoresists are cross linking negative tone materials optimized for use in plating, TSV, RIE etch and high energy implant applications. The fully cross linked features are extremely thermally stable and etch resistant, yet strip quickly and easily in most common photoresist removers (AZ 400T Stripper recommended). The 115cps version covers a coated film thickness range of approximately 3.5 to 6.0µm. Develop is very fast in standard MIF Developers (less than 2 minutes in AZ 300MIF for a resist film thickness of 6.0µm). No post bake re-hydration delay required.
