Lithographic wetbench for coating (SUSS-WETBENCH)


Erik Pálesch

The wetbench is a complete basic setup for substrate coating. It consists of built-in spin-coater LabSpin 6 for manual resist dispense, two hot plate modules HP8, and one vapour primer VP8 for HMDS coating (adhesion promoter). It is possible for all built-in equipment to programm recipes for more customized applications. See specifications for more details.
