Abstract: Disclosed is a thin film stress control-based coating method for large-area coating. The method uses a two-step coating process in which a first coating layer that is a relatively low-hardness layer is primarily formed on a base member and a second coating layer that is a relatively high-hardness layer is secondarily formed on the first coating layer. The method can form a high-density coating structure that is hardly peeled off over a relatively large area compared to conventional coating methods by suppressing internal stress of the coating layers of the coating structure. Further disclosed is a coating structure manufactured by the same method.

Abstract: A method for forming a Ta2O5 capacitor on a semiconductor device reduces leakage current and increases cell capacitance by utilizing a two-step rapid thermal nitridation (RTN) process to form a nitride layer on a hemi-spherical grain (HSG) storage node. The first RTN process is performed in a NH3 atmosphere at 800±40° C. for 180±60 seconds, thereby forming a nitride layer having a thickness of about 4 Å. The second RTN process is performed in a NH3 atmosphere at 850±40° C. for 180±60 seconds, thereby increasing the thickness of the nitride layer to at least about 7 Å. Therefore, a nitride layer that is thick enough to act as an oxidation barrier is achieved, but agglomeration of the HSGs on the storage node due to high process temperatures is prevented.
