摘要:
A method for fabricating a cylindrical capacitor. The method includes forming an isolation structure including an interlayer on a substrate, the substrate having a plurality of contact plugs formed therein, forming a plurality of opening regions by etching the isolation structure, thereby exposing selected portions of the contact plugs, forming storage nodes on a surface of the opening regions, etching selected portions of the isolation structure to form a patterned interlayer that encompasses selected portions of the storage nodes, thereby supporting the storage nodes, removing remaining portions of the isolation structure, and removing the patterned interlayer to expose inner and outer walls of the storage nodes.

A method for forming a zirconium oxide (ZrO2) layer on a substrate in a chamber includes controlling a temperature of the substrate; and repeating a unit cycle of an atomic layer deposition (ALD) method. The unit cycle includes supplying a zirconium (Zr) source into a chamber, parts of the Zr source being adsorbed into a surface of the substrate; purging non-adsorbed parts of the Zr source remaining inside the chamber; supplying a reaction gas for reacting with the adsorbed parts of the Zr source; and purging non-reacted parts of the reaction gas remaining inside the chamber and reaction byproducts, wherein the temperature of the substrate and a concentration of the reaction gas are controlled such that the ZrO2 layer is formed with a tetragonal structure.
