摘要
Systems and methods for rapid generation of ALD saturation curves using segmented spatial ALD are disclosed. Methods include introducing a substrate, having a plurality of substrate segment regions, into a processing chamber. The substrate may be disposed upon a pedestal within the chamber. Sequentially exposing the plurality of segment regions to a precursor within the chamber at a first processing temperature. Afterwards, purging the precursor from the chamber and then sequentially exposing each plurality of segment regions to a reactant within the chamber at the first processing temperature. Afterwards, purging the reactant from the chamber. Repeat sequentially exposing the plurality of segment regions to the precursor and the reactant for a plurality of cycles. Each segment region may be sequentially exposed to the precursor for a unique processing time. The pedestal may be rotated prior to exposing each next segment region to the precursor and the reactant.
