Abstract:
1. A method for fabricating a semiconductor device with a high-K layer, comprising: providing a substrate; forming NH passing an inert gas through a solution containing a first precursor comprising a first precursor molecule of the NH transferring the first precursor gas onto the substrate such that the substrate absorbs the first precursor gas molecules by a chemical absorption process to spread individual first precursor gas molecules on a surface of the substrate; removing the unabsorbed first precursor gas using a first inert gas; after transferring the first precursor gas and removing the unabsorbed first precursor gas, applying a second precursor gas on the substrate; forming a first thin film on the substrate as a reaction product of the second precursor gas and the absorbed first precursor gas molecules; removing unreacted second precursor gas and byproducts using a second inert gas; and forming a high-K layer on the substrate by forming a plurality of the first thin films layer-by-layer.
