Patent ID: 10685275

Abstract:
Embodiments of the invention relate to processes for fabricating a smart device, 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 interposing a flexible film having conductor pattern thereon, at least one flip chip for operating the smart card device is embedded in a first substrate such that the first substrate provides an encapsulation to the at least one flip chip, wherein the at least one flip chip is arranged at a position in a first vertical plane; and a contact pad, 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 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.
