发明名称 Fabrication of high-density capacitors for mixed signal/RF circuits
摘要 A method for fabricating a capacitor on a semiconductor substrate is disclosed. The method may include simultaneously forming at least one via and at least one upper capacitor plate opening in a first dielectric layer having an underlying cap dielectric layer deposited over a first material region having a first conductive material within a conductive region and forming a trench above the via. The underlying cap dielectric layer may be modified in a way that increases its dielectric constant as a result of simultaneously be heated by a heat source and impinged with and energy beam. The method may also include filling the via, trench, and upper capacitor plate opening with a second conductive material resulting in an integrated circuit structure and employing CMP to remove any excess second conductive material from the integrated circuit structure.
