Latest Patents

Duenas holds a patent for "Thin film capacitors and process for making them." This invention pertains to a thin film capacitor designed for use in semiconductor integrated circuit devices, including analog circuits, RF circuits, and dynamic random access memories (DRAMs). The capacitor features a dielectric thickness of less than about 50 nm, a capacitance density of at least about 15 fF/μm², and a breakdown field of at least about 1 MV/cm. The dielectric material utilized is a metal oxide, which can be titanium, niobium, or tantalum, and may also contain silicon or nitrogen. The fabrication process involves depositing the metal onto a substrate or a first electrode, followed by anodic oxidation to achieve the desired dielectric thickness. A top electrode is then formed over the dielectric layer, ensuring that it does not compromise the electrical characteristics of the capacitor.
