Abstract:
1. A semiconductor structure comprising: an array of interposer units, wherein at least one interposer unit in said array is conductively connected to a first semiconductor chip and a second semiconductor chip, and each interposer unit in said array is not of integral construction with any other interposer unit in said array; first solder balls and second solder balls, wherein each of said first solder balls contacts a lower contact pad of an interposer unit and a first contact pad of said first semiconductor chip, and each of said second solder balls contacts an upper contact pad of said interposer unit and a second contact pad of said second semiconductor chip; and an interposer-frame means for holding each interposer unit in said array of interposer units in a fixed position relative to other interposer units in said array, wherein said interposer-frame means is embedded in a molding compound structure located between said first and second semiconductor chips.
