Abstract
Methods for forming capacitors of semiconductor devices, and more specifically, to a method for forming a capacitor having a stacked structure of metal layer-insulating film-metal layer and having its storage electrode formed of ruthenium (hereinafter, referred to as 'Ru') and dielectric layer formed of tantalum oxide (Ta O ) film, which provides improved formation of dense Ru film using a CVD method at high temperature, thereby improving electrical characteristics of the capacitor.
