Summary:PURPOSE: To provide an inexpensive and highly reliable semiconductor package which enables direct adhesion without adopting die-attaching technique which is usually used when mounting a semiconductor element in a a semiconductor package production process. CONSTITUTION: A semiconductor package is obtained, wherein a metallic base substrate with a copper foil layer wherein a circuit is machined through an insulation layer on a metallic plate is used and a semiconductor element is thermally compressed directly on an adherent insulation layer wherein a semiconductor package with a brim part which is machined into a soup dish shape through press molding, etc., in the metallic base substrate.
