    摘要: In some embodiments, a multi-layer dielectric structure, such as a capacitor dielectric region, is formed by forming a first dielectric layer on a substrate according to a CVD process and forming a second dielectric layer directly on the first dielectric layer according to an ALD process. In further embodiments, a multi-layer dielectric structure is formed by forming a first dielectric layer on a substrate according to an ALD process and forming a second dielectric layer directly on the first dielectric layer according to a CVD process. The CVD-formed layers may comprise one selected from the group consisting of SiO2, Si3N3, Ta2O5, HfO2, ZrO2, TiO2, Y2O3, Pr2O3, La2O3, Nb2O5, SrTiO3 (STO), BaSrTiO3 (BST) and PbZrTiO3 (PZT). The ALD-formed layers may comprise one selected from the group consisting of SiO2, Si3N3, Al2O3, Ta2O5, HfO2, ZrO2, TiO2, Y2O3, Pr2O3, La2O3, Nb2O5, SrTiO3 (STO), BaSrTiO3 (BST) and PbZrTiO3 (PZT).

    摘要: A method of monitoring a density profile of impurities, the method including presetting a monitoring position of a thin layer coated on a substrate, the density profile of impurities being monitored from the monitoring position in a direction of thickness of the thin layer, moving an exposer for exposing a local area of the thin layer to the monitoring position, exposing the local area of the thin layer along the direction of thickness of the thin layer, forming a shape profile of the exposed local area of the thin layer, and monitoring the density profile of impurities by determining a density of impurities in accordance with the shape profile, and an apparatus therefor. The impurity density profile may be monitored without destroying a substrate on which a thin layer is coated, and an amount of impurities used for forming the thin layer may be monitored and controlled in real-time.
