Abstract:
1. A semiconductor device comprising: a silicon substrate having a plurality of electrode pads formed at an outer peripheral portion thereof and circuit blocks including an analog circuit formed in an inner circuit forming surface; an insulating layer formed over the surface of the silicon substrate; a plurality of redistribution wirings formed over the surface of the insulating layer and formed from a metallic thin film, said redistribution wirings connecting the electrode pads to predetermined external connecting positions; a shield section in which a plurality of strip metallic conductors are disposed in parallel at predetermined intervals over the analog circuit, the ends or centers of these strip metallic conductors being connected to one another, and the shield section having a portion that is connected to an external connecting position; metallic posts at the external connecting positions, for electrically and mechanically connecting the redistribution wirings and the shield section to the outside; and an encapsulating resin which exposes leading ends of the metallic posts and seals side surfaces of the metallic posts, the insulating layer, the redistribution wirings and the shield section, the encapsulating resin being disposed directly on the strip metallic conductors.
