Latest Patents

Marshall O Cathey, Jr. holds a patent for "Forming integrated circuit devices with metal-insulator-metal capacitors using selective etch of top electrodes." This patent describes a method of forming integrated circuits (IC) that includes at least one metal-insulator-metal (MIM) capacitor. The process involves forming a bottom electrode on a predetermined region of a semiconductor surface of a substrate. A dielectric layer, including silicon, is then formed on the bottom electrode, with a thickness of less than 1,000 A. A top electrode layer is subsequently formed on the dielectric layer. The method employs a patterned masking layer and utilizes dry-etching techniques to etch the top electrode layer outside the patterned masking layer, effectively reaching the dielectric layer while removing no more than 100 A of its thickness. The dry etch process incorporates a first halogen gas, a second halogen gas that contains fluorine, and a carrier gas. This innovative approach significantly improves the fabrication of integrated circuits.
