Abstract
A 3-D stackable semiconductor package includes a first component and a second component. The semiconductor package is formed by stacking the back of the first component and the back of the second component together. The metal pads on the surfaces of the first component and the second component are redistributed to the edge of the first and the second components by a redistribution layer. A plurality of electric conduction posts is formed at the edge of the first and the second component to transmit electric signals between them. The semiconductor package transmits electric signals to the PCB by the electric conductive bumps.

A 3-D stackable semiconductor package, comprising:
- a first component having a first top surface and a first bottom surface corresponding to each other, said first top surface having at least one first metal pad connected to the edge thereof by a first redistribution layer;
- a second component having a second top surface and a second bottom surface corresponding to each other, said second bottom surface connected to the first bottom surface, so that the first component stacked on the second component, said second top surface having at least one second metal pad, said second metal pad connected to the edge of the second top surface by a second redistribution layer and having a electric conductive bump respectively;
- and
- an electric conduction post formed at the edge of the first component and the second component to electrically connect the first redistribution layer and the second redistribution layer so as to form a stackable semiconductor package.
