Abstract

Die may be thinned using a thinning and/or a polishing process. Such thinned die may be flexible and may change operational characteristics when flexed. The flexible die may be applied to a mechanical carrier (e.g., a PCB) of a card or device. Detection circuitry may also be provided on the PCB and may be used to detect changed operational characteristics. Such detection circuitry may cause a reaction to the changed characteristics by controlling other components on the card or device based upon the flex-induced changed characteristics. The thinned die may be stacked, interconnected, and encapsulated between sheets of laminate material to form a flexible card or device.
