Abstract
The semiconductor device comprises a first area and a second area positioned adjacent to the outside of the first area, the semiconductor substrate having a main surface and side surfaces and disposed in such a manner that the main surface is positioned in the first area and each of the side surfaces is positioned at a boundary between the first area and the second area, a plurality of pads formed over the main surface of the semiconductor substrate and a plurality of external connecting terminals formed thereon, which are respectively electrically connected to the pads, a first resin portion which is formed over the main surface of the semiconductor substrate so as to cover the pads and has a main surface and side surfaces, and which is formed in such a manner that the external connecting terminals are exposed from the main surface and each of the side surfaces is positioned at the boundary, and a second resin portion which is positioned in the second area and formed so as to cover the side surfaces of the semiconductor substrate and the side surfaces of the first resin portion and which is different in composition from the first resin portion.
