Wireless memory device
First Claim
1. A wireless memory device, comprising:
- a substrate;
an antenna carried on the substrate; and
an adhesive layer coupled to the substrate for movement with respect thereto between a first position proximate the substrate and a second position spaced from the substrate with respect to the first position while coupled to the substrate.

Abstract
A memory device comprises a substrate, an antenna on a first surface of the substrate, a microelectronic structure coupled to the antenna, a selectively deformable intermediate layer covering the first surface, the antenna and the microelectronic structure and conforming thereto, and an adhesive layer covering the intermediate layer. The intermediate layer may be deformable for selectively positioning the antenna with respect to the adhesive, and positioning the antenna with respect to an item to which the memory device is secured. The intermediate layer may be compressed, creating a relatively low profile for printing on the memory device. The intermediate layer may be an elastomerically compressible material, such as foam, or may be a selectively pressurizable and deformable envelope. A substantially planar surface of the intermediate layer provides a smooth surface for further manufacturing steps such as forming a protective film layer, a conductive ground layer, or for depositing adhesive and die cutting the RF tag onto a release liner. A face sheet may be positioned on the second surface of the substrate to provide a smooth surface for printing. Alternatively, the intermediate layer may provide a substantially planar surface for the face sheet. The ground layer may be formed from a spent transfer ribbon. A second ground layer and a dielectric layer may form a capacitor.
