ALEXANDRIA, Va., March 3 -- United States Patent no. 12,568,679, issued on March 3, was assigned to MURATA MANUFACTURING Co. LTD. (Nagaokakyo, Japan).

"Contact structures in RC-network components" was invented by Yohei Yamaguchi (Nagaokakyo, Japan), Yasuhiro Murase (Nagaokakyo, Japan) and Stephane Bouvier (Cairon, France).

According to the abstract* released by the U.S. Patent & Trademark Office: "RC-network components that include a substrate having a capacitor with a thin-film top electrode portion at a surface at one side of the substrate. The low ohmic semiconductor substrate is doped to contribute 5% or less to the resistance of the RC-network component. The resistance in series with the capacitor is controlled by providing a contact...
