Abstract
A method for depositing a barrier layer includes a) arranging a substrate including a nitride layer in a processing chamber; b) setting a process temperature in the processing chamber to a predetermined process temperature range; c) setting a process pressure in the processing chamber to a predetermined process pressure range; d) supplying at least one of a gas and a vapor including an organosilane precursor species; and e) depositing a barrier layer on the nitride layer. The barrier layer reduces diffusion of nitrogen-containing groups in the nitride layer into a photoresist layer that is subsequently deposited on the nitride layer.
