PROBLEM TO BE SOLVED: To provide a high wiring density and a strict dimensional tolerance in a multi-layer circuit board. SOLUTION: The multi-layer circuit board includes a dielectric base board 30, and a sacrificial structure 38 formed on a base board 30 and a conductor 36. The sacrificial structure 38 defines a region protected from the deposition of a dielectric layer. The sacrificial structure 38 is removed after the dielectric layer is deposited to form a dielectric thin film layer patterned on the base board 30 and the conductor 36. COPYRIGHT: (C)2010,JPO&INPIT
