摘要： Radio frequency identification (RFID) tags and processes for manufacturing the same. The RFID device generally includes (1) a metal antenna and/or inductor; (2) a dielectric layer thereon, to support and insulate integrated circuitry from the metal antenna and/or inductor; (3) a plurality of diodes and a plurality of transistors on the dielectric layer, the diodes having at least one layer in common with the transistors; and (4) a plurality of capacitors in electrical communication with the metal antenna and/or inductor and at least some of the diodes, the plurality of capacitors having at least one layer in common with the plurality of diodes and/or with contacts to the diodes and transistors.

摘要： A MOS RF surveillance and/or identification tag, and methods for its manufacture and use. The tag generally includes an interposer, an antenna and/or inductor on the interposer, and integrated circuitry on the interposer in a location other than the antenna and/or inductor. The integrated circuitry generally has a lowest layer in physical contact with the interposer surface. The method of manufacture generally includes forming a lowest layer of integrated circuitry on an interposer, forming successive layers of the integrated circuitry on the lowest layer of integrated circuitry, and attaching an electrically conductive functional layer to the interposer. Alternatively, an electrically conductive structure may be formed from a functional layer attached to the interposer. The method of use generally includes causing and/or inducing a current in the present tag sufficient for it to generate, reflect or modulate a detectable electromagnetic signal, detecting the signal, and optionally, processing information conveyed by the detectable electromagnetic signal. The present invention advantageously provides a low cost RFID tag capable of operating at MHz frequencies that can be manufactured in a shorter time period than conventional RFID tags that manufacture all active electrical devices on a conventional wafer.

摘要： Integrated circuits and methods of permanently disabling integrated circuits are disclosed. An integrated circuit having an erasable non-volatile memory adapted to store an activation code and logic to disable the integrated circuit when the code in the erasable non- volatile memory has been altered or erased after it has been separated from a substrate, is placed into an electromagnetic field of sufficient power to erase or reprogram the erasable non-volatile memory. The entire integrated circuit is permanently disabled by erasing, altering, or reprogramming the erasable non-volatile memory. In preferred embodiments, the integrated circuit comprises a non-erasable non-volatile memory storing the activation code, and circuitry adapted to permanently disable the integrated circuit when the code in the erasable non-volatile memory does not match the activation code in the non-erasable non-volatile memory. Erasing, altering, or reprogramming the erasable non-volatile memory results in a mismatch of the non-volatile memories, which permanently deactivates the integrated circuit.

摘要： Printed integrated circuitry and attached antenna and/or inductor for sensors, electronic article surveillance (EAS), radio frequency (RF) and/or RF identification (RFID) tags and devices, and methods for its manufacture. The tag generally includes printed integrated circuitry on one carrier and an antenna and/or inductor on another carrier, the integrated circuitry being electrically coupled to the antenna and/or inductor. The method of manufacture generally includes of printing an integrated circuit having a plurality of first pads on a carrier, forming an antenna and/or inductor having a plurality of second pads on a substrate, and attaching at least two of the first pads of the printed integrated circuit to corresponding second pads of the antenna and/or inductor. The present invention advantageously provides a low cost RFID tag capable of operating at MHz frequencies that can be manufactured in a shorter time period than conventional RFID tags that manufacture all active electrical devices on a conventional wafer.

摘要： The present invention relates to surveillance and/or identification devices having capacitors connected in parallel or in series, and methods of making and using such devices. Devices with capacitors connected in parallel, where one capacitor is fabricated with a relatively thick capacitor dielectric and another is fabricated with a relatively thin capacitor dielectric achieve both a high-precision capacitance and a low breakdown voltage for relatively easy surveillance tag deactivation. Devices with capacitors connected in series result in increased lateral dimensions of a small capacitor. This makes the capacitor easier to fabricate using techniques that may have relatively limited resolution capabilities.

摘要： The present invention relates to electrically active devices (e.g., capacitors, transistors, diodes, floating gate memory cells, etc.) having dielectric, conductor, and/or semiconductor layers with smooth and/or dome-shaped profiles and methods of forming such devices by depositing or printing (e.g., inkjet printing) an ink composition that includes a semiconductor, metal, or dielectric precursor. The smooth and/or dome-shaped cross-sectional profile allows for smooth topological transitions without sharp steps, preventing feature discontinuities during deposition and allowing for more complete step coverage of subsequently deposited structures. The inventive profile allows for both the uniform growth of oxide layers by thermal oxidation, and substantially uniform etching rates of the structures. Such oxide layers may have a uniform thickness and provide substantially complete coverage of the underlying electrically active feature. Uniform etching allows for an efficient method of reducing a critical dimension of an electrically active structure by simple isotropic etch.

摘要： Semiconductor devices on a diffusion barrier coated metal substrates, and methods of making the same are disclosed. The semiconductor devices include a metal substrate, a diffusion barrier layer on the metal substrate, an insulator layer on the diffusion barrier layer, and a semiconductor layer on the insulator layer. The method includes forming a diffusion barrier layer on the metal substrate, forming an insulator layer on the diffusion barrier layer; and forming a semiconductor layer on the insulator layer. Such diffusion barrier coated substrates prevent diffusion of metal atoms from the metal substrate into a semiconductor device formed thereon.
