Full equipment name: YES-5E Vacuum Bake / Vapour Prime Processing System (Serial # 88487)
General purpose:The YES HMDS system combines vapor priming and vacuum dehydration baking.
Hexamethyldisilazane (HMDS) is used to improve photoresist adhesion to oxides. The HMDS reacts with the oxide surface in a process known as silylation, forming a strong bond to the surface. The methyls, meanwhile, will bond with the photoresist, enhancing the photoresist adhesion.
