摘要
Semiconductor packages, and methods for making the semiconductor packages, having an interposer structure with one or more interposer and an extension platform, which has an opening for placing the interposer, and the space between the interposer and the extension platform is filled with a polymeric material to form a unitary interposer-extension platform composite structure. A stacked structure may be formed by at least a first semiconductor chip coupled to the interposer and at least a second semiconductor chip coupled to the extension platform, and at least one bridge extending over the space that electrically couples the extension platform and the interposer. The extension platform may include a recess step section that may accommodate a plurality of passive devices to reduced power delivery inductance loop for the high-density 2.5D and 3D stacked packaging applications.
