Abstract
Methods, algorithms, processes, circuits, and/or structures for laser patterning suitable for customized RFID designs are disclosed. In one embodiment, a method of laser patterning of an identification device can include the steps of: (i) depositing a patternable resist formulation on a substrate having configurable elements and/or materials thereon; (ii) irradiating the resist formulation with a laser tool sufficiently to change the solubility characteristics of the resist in a developer; and (iii) developing exposed areas of the resist using the developer. Embodiments of the present invention can advantageously provide a relatively low cost and high throughput approach for customized RFID devices.
