Abstract
Chip-size semiconductor packages (“CSPs”) containing multiple stacked dies are disclosed. The dies are mounted on one another in a stack such that corresponding ones of the vias in the respective dies are coaxially aligned. An electrically conductive wire or pin is in each set of aligned vias and soldered to corresponding ones of the terminal pads. The pins include portions protruding from the stack of dies that serve as input-output terminals of the package. Heat spreaders can be interleaved between the stacked dies to enhance heat dissipation from the package.
