Abstract
A process of producing a conducting material suitable for being filled in TSVs for LSI chip 3D package, etc. includes that a solution containing a monomer that provides a conducting polymer, anions, and metal ions such as Agor Cuis irradiated with ultraviolet radiation or light having the energy necessary for exciting electrons up to an energy level capable of reducing the metal ions to precipitate a conducting polymer/metal composite. This enables an electrical conductor of high electrical conductivity to be precipitated faster than could be achieved by conventional processes.
