A semiconductor device package includes a semiconductor chip including a conductive pad, a die pad on which the semiconductor chip is mounted and having a first thickness, a lead pattern including a first portion disposed adjacent to the edge of the die pad and having the first thickness and a second portion having a second thickness greater than the first thickness, a heat radiation member disposed on the die pad and the lead pattern and including a groove formed at its bottom surface, and a conductive line disposed to electrically connect the conductive pad to the lead pattern corresponding to the conductive pad and partially inserted into the groove.

Method of fabricating a semiconductor device package including a heat radiation plate

A circuit board and a semiconductor package having the same are provided. The circuit board comprises a base substrate having interconnections, and solder ball lands disposed on one surface of the base substrate. The solder ball lands respectively have land holes having different sizes. The land hole disposed at the center portion of the base substrate and the land hole disposed at the edge portion of the base substrate may have different sizes. For example, the sizes of the land holes may increase from the center portion of the base substrate to the edge portion thereof, and alternatively, the sizes of the land holes may decrease from the center portion of the base substrate to the edge portion thereof.
