Hexamethyldisilazane (HMDS) is an adhesion promoter between photoresist and the silicon wafer.
MCC Primer 80/20
MicoChem Primer 80/20 is based on a combination of 20% HMDS and 80% PM Acetate. HMDS is the best known chemical pre-treatment for increasing photoresist adhesion to oxides, nitrates, polysilicon, glass, quartz and other difficult surfaces. PM Acetate acts as an effective pre-wetting agent.
MICROPOSITPrimers are based upon hexamethyldisilizane (HMDS), a well-known chemical pretreatment for increasing photoresist adhesion to doped and undoped oxides, nitride, polysilicon, glass, quartz and other semiconductor surfaces.
