    摘要： A semiconductor package uses no thermosetting adhesive for mounting a heat slug thereon, which adhesive requires a strict control during the storage and the production thereof. A semiconductor package comprises a circuit board having respective surfaces and an opening; a conductive layer formed on one of the surfaces of the circuit board so that the conductive layers are retracted from a peripheral edge of the opening by a certain distance; a heat slug attached to the one surface of the circuit board by means of solder so that the opening is closed at the one surface and opened at the other surface to form a cavity within which a semiconductor element mounting area is defined; and the heat slug is provided with a groove along a periphery of the semiconductor element mounting area and adjacent the peripheral edge of the opening.
