METHODS AND APPARATUS FOR ATOMIC LAYER DEPOSITION ON LARGE AREA SUBSTRATES

A method for depositing one or more materials on a substrate comprises placing at least a portion of the substrate proximate to a plurality of deposition modules such that the substrate and each of the plurality of deposition modules define a respective one of a plurality of process spaces therebetween. Each of the plurality of process spaces is in fluidic communication with one or more of a plurality of draw gas injection chambers. Subsequently, a first precursor gas and a second precursor gas are separately injected into the plurality of process spaces while injecting a draw gas into the plurality of draw gas injection chambers, and a sweep gas is injected into the plurality of process spaces while injecting substantially no draw gas into the plurality of draw gas injection chambers.
