WebHMDS is a purified hexamethyldisilazane with the chemical formula [ (CH3)2Si]2NH. The product is used to augment the adhesion of photoresist on silicon and SiO2 surfaces. The effectiveness of HMDS on adhesion is correlated with the reactivity of this compound with surface hydroxyl groups to form a new siloxane end product, i.e. Si-O-Si (CH3)3.
