  • Patent number: 9400953
    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.

  • Publication number: 20070295456
    Abstract: A material for bonding a first wafer to a second wafer, which includes an insulating adhesive with conductive particles embedded in the adhesive substance. When the adhesive is applied and melted or fused, and pressure is applied between the first wafer and the second wafer, the first wafer approaches the second wafer until a minimum separation is reached, defined by a dimension of the conductive particles. Each of the first wafer and the second wafer may have circuitry formed thereon, and the conductive particles may form a conductive path between the circuitry on one wafer and the circuitry on the other wafer. Advantageously, the high fusing temperature required by the insulating adhesive may also serve to activate a getter material, formed in the device cavity between the first wafer and the second wafer.
