Packaged Semiconductor Device with Encapsulant Embedding Semiconductor Chip that Includes Contact Pads

摘要

A method of manufacturing a semiconductor package includes embedding a semiconductor chip in an encapsulant. First contact pads are formed on a first main face of the semiconductor package and second contact pads are formed on a second main face of the semiconductor package opposite the first main face. A diameter d in micrometers of an exposed contact pad area of the second contact pads satisfies d≧(8/25)x+142 μm, where x is a pitch of the second contact pads in micrometers.
