Title: Nozomi Tanifuji: Innovator in Multilayer Ceramic Substrates
Introduction
Nozomi Tanifuji is a prominent inventor based in Nagoya, Japan. She has made significant contributions to the field of multilayer ceramic substrates, holding a total of 3 patents. Her innovative methods have advanced the manufacturing processes in this specialized area.
Latest Patents
Tanifuji's latest patents include a method of manufacturing multilayered ceramic substrates. This method involves forming a capacitor layer on a green sheet of low-temperature co-firable ceramic through printing. The green sheet with the capacitor layer is laminated with other green sheets to create a substrate laminate. Additionally, two release green sheets of alumina are laminated to the top and bottom of the substrate laminate. The laminate is then fired at temperatures between 800°C and 1,000°C under specific pressure conditions. After firing, the release green sheets are removed, and a wiring pattern is printed on the substrate, which is subsequently fired again.
Another notable patent is the process for producing a multilayer ceramic circuit substrate. This method includes internal conductor patterns made of tungsten and/or molybdenum, and surface conductor patterns made of copper. An intermediate metal layer is formed in the through-holes of the surface layer, ensuring excellent bonding strength and electrical conductivity between the internal and surface conductors. This innovation allows for high precision wiring and miniaturization of electronic circuit parts.
