Abstract:
A method of fabricating a metal-insulator-metal (MIM) capacitor, said method comprising the steps of:a) receiving a laminate comprising in order a first metal layer, a first barrier layer, a dielectric layer, a second barrier layer, and a second metal layer; b) removing a portion of said first metal layer, a portion of said first barrier layer, and a portion of said dielectric layer to form a first electrode of said MIM capacitor, leaving a portion of said second barrier layer exposed; c) applying an anti-reflective coating to said first electrode and to said portion of said second barrier layer that is exposed, wherein said ARC is an organic ARC; d) removing a portion of said second barrier layer and a portion of said second metal layer to form a second electrode of said MIM capacitor; and e) removing organic ARC remaining after said step d) is performed.
