Patent ID: 8097933

Claim:
A flexible semiconductor package, comprising: a flexible substrate; a data chip disposed over the flexible substrate and including a data storage unit for storing data and first bonding pads electrically connected to the data storage unit; a control chip disposed over the flexible substrate and including a data processing unit for processing the data in the data chip and second bonding pads electrically connected to the data processing unit; a wiring electrically connecting the first bonding pads to the second bonding pads; a plurality of first bumps interposed between a first bonding pad of the data chip and the wiring; a plurality of second bumps interposed between a second bonding pad of the control chip and the wiring; wherein the wiring comprises: a first coupling recess, wherein the first bump is inserted in the first coupling recess to increase a contact area between the wiring and the first bump; and a second coupling recess, wherein the second bump is inserted in the second coupling recess to increase a contact area between the wiring and the second bump.
