Title: Method for fabricating capacitor which can prevent characteristics deterioration of bottom electrode
Inventor: KWON SOON YONG
IPC: H01L27/10
Filed: 1998-12-24
Abstract: PURPOSE: A method for fabricating a capacitor is provided which can prevent the deterioration of the characteristics of a bottom electrode. CONSTITUTION: A method prevents the deterioration of the characteristics of a bottom electrode by suppressing atoms composing an adhesion film(13) from being diffused to a Pt bottom electrode, as maintaining the adhesive power of the Pt bottom electrode and a bottom oxide. The bottom electrode is formed with Zr, Nb, Mo, Hf or W having larger atomic radius than Ti among active metals having high affinity with oxygen. As the atomic radius of the active metal used as the adhesion film becomes larger, the diffusion into the bottom electrode Pt layer(14,16) is reduced. This reduces the surface roughness of the bottom electrode and has a great influence on the yield improvement of a device.
