Claim:
1. A method of manufacturing a semiconductor package, the method comprising, in a following order: a mounting step of bonding a semiconductor element onto an upper surface of a die pad; a connection step of electrically connecting the semiconductor element and a lead via a connecting member; a surface treatment step of performing a surface treatment with a silane coupling agent on surfaces of the semiconductor element, the connecting member and portions of the die pad, and the lead; and a sealing step of sealing with a sealing resin, the semiconductor element, the connecting member and portions of the die pad and the lead; wherein a first surface of a plurality of surfaces of the semiconductor element includes a first region where an organic substance is exposed, and a second region where an inorganic substance is exposed, a portion of the second region being electrically bonded with the connecting member, and a bonding strength between the first region and the sealing resin is weaker than a bonding strength between the second region and the sealing resin.
