Latest Patents

Vu Q Ho's latest patents include a groundbreaking structure and method for making a capacitor for an integrated circuit. The capacitor structure is designed for memory elements and is formed within a via hole defined through a first dielectric layer. This innovative design features a bottom electrode created by an underlying conductive layer, with a capacitor dielectric filling the via and a dielectric barrier layer lining the via. The capacitor dielectric is characterized by high dielectric strength, preferably utilizing a ferroelectric material. An overlying conductive layer serves as the top electrode, ensuring effective contact with the capacitor dielectric. The simplicity and compactness of this capacitor structure allow for fabrication using established CMOS, Bipolar, or Bipolar-CMOS processes for submicron VLSI and ULSI integrated circuits.

The method for making this capacitor involves several steps, including providing a first conductive electrode and forming a layer of a first dielectric material. A via hole is opened through the dielectric layer, and a capacitor dielectric with higher dielectric strength is introduced. The process culminates in the formation of a second conductive electrode, with planarization achieved through chemical mechanical polishing to ensure a fully planar topography. This method results in a capacitor that is not only simple and compact but also compatible with various integrated circuit processes.
