Method for embedding integrated circuit flip chip
Abstract:
Embodiments of the invention relate to processes for fabricating a smart device (200), e.g. smart card, and configurations for smart card devices with greater reliability and lifespan, and improved finish. In the smart card device comprising of laminated substrate layers (220, 240) interposing a flexible film (230) having conductor pattern thereon, at least one flip chip (250) for operating the smart card device is embedded in a first substrate (220) such that the first substrate provides an encapsulation to the at least one flip chip, wherein the at least one flip chip (250) is arranged at a position in a first vertical plane; and a contact pad (260), for providing electrical connection when the smart card device is inserted into a smart card reader, is arranged at a position in a second vertical plane, wherein the first vertical plane is non-overlapping with the second vertical plane. The contact pad (260) is projected through a cavity in a second substrate to form a continuous even plane from an outer surface of the laminated substrate layers to the contact pad (260).
