A semiconductor device is provided with a semiconductor package 2 and a package substrate 5 having lands 8 that electrically connect by way of solder bumps 4 to the semiconductor package 2. A plurality of columns, in each of which a multiplicity of lands 8 are arranged, are formed on the package substrate 5. At least one of the lands 8 that make up columns that are located closest to each of the main sides that make up the outer edges of the semiconductor package has an interconnection 9 that extends from the land 8 along the surface of the package substrate. The interconnection 9 is formed such that the part that contacts the land 8 is located closer to a line that passes through the center of the land 8 and that is orthogonal to a line that connects the center of the land 8 with the center of the semiconductor package 2 than to the line that connects the center of the land 8 with the center of the semiconductor package 2.

A semiconductor device capable of reducing a temperature increase during operation thereof is provided. In the semiconductor device, an interface chip is stacked on a plurality of stacked semiconductor elements. Both an “Si” interposer and a resin interposer are arranged under the plural semiconductor elements. The Si interposer is arranged between the resin interposer and the plural semiconductor elements. The Si interposer owns a thickness which is thicker than a thickness of a semiconductor element, and also has a linear expansion coefficient which is smaller than a linear expansion coefficient of the resin interposer, and further, is larger than, or equal to linear expansion coefficients of the plural semiconductor elements.

A semiconductor chip is mounted on a flexible wiring board through the interposition of an elastmer. The flexible wiring board is made up of a tape on which wiring is fixed. A part of the wiring is projected beyond the edge of the tape, extended in the direction of the thickness of the elastmer and connected to an electrode of the semiconductor chip. The edge of the tape beyond which the wiring is projected protrudes beyond the edge of the elastmer by a length no smaller than the thickness of the elastmer.
