Abstract
A contact converting structure of a semiconductor chip comprises a semiconductor chip with a group of electrodes arranged on a surface of one side thereof. A liquid crystal polymer film is bonded to the surface in such a manner as to cover the electrodes group, and a group of external contacts is arranged on the other surface of the semiconductor chip. The external contacts group is connected to the electrodes group through the liquid crystal polymer film. A process for manufacturing a semiconductor chip having such a contact converting structure is also disclosed.
