Abstract

A semiconductor package for a semiconductor chip, e.g., a memory chip, is disclosed. The semiconductor package includes a substrate having a generally rectangular perimeter with four sidewalls and a chamfer between adjacent first and second ones of the sidewalls. The memory chip is electrically coupled contacts provided on an opposite surface of the substrate. The contacts are in a row along only the one sidewall of the substrate. A body of a plastic encapsulant covers the first surface of the substrate, the memory chip, and at least two of the sidewalls of the package. The entire perimeter of the substrate, including all four sidewalls and the chamfer, are covered by the plastic encapsulant. Alternatively, only two or three of the sidewalls are covered by the plastic encapsulant, with the other sidewall(s) being exposed and vertically coplanar with a respective sidewall of the plastic encapsulant.
