Abstract

A wafer processing method relates to treating a semi-conductor wafer and in particular, but not exclusively, to planarization. The method consists of depositing a liquid short-chain polymer formed from a silicon containing gas or vapor. Subsequently water and OH are removed and the layer is stabilised.
