Abstract:
A semiconductor device includes a semiconductor chip (11) having a top surface and a bottom surface, a plurality of leads (14) arranged under the bottom surface of the semiconductor chip (11), where the leads (14) have first ends (14a) electrically coupled to the semiconductor chip (11) and second ends which form external terminals (16) and each of the external terminals have a bottom surface, and a package (17, 31) encapsulating the semiconductor chip (11) and the leads (14) so that the bottom surface of each of the external terminals (16) is exposed at a bottom surface (17a, 31a) of the package (17, 31) and remaining portions of the leads (14) are embedded within the package (17, 31), where the package (17, 31) has a size which is approximately the same as that of the semiconductor chip (11) in a plan view viewed from above the top surface of the semiconductor chip (11).
