Popis: Different precursors for atomic layer deposition of carbon doped silicon oxide have been investigated. The impact of precursor reactivity, the number of silicon-carbon bonds in the precursor, oxidant concentration and dosing time, and deposition temperature on deposited film's carbon content are discussed. It is found that substituting the Si-H by Si-CH3 reduces precursor reactivity and decreases film growth per cycle (GPC). At temperatures higher than 225 °C, all the precursors could deposit a silicon oxide films with reasonable GPC but with very little carbon in the film (
