    • A two-terminal fuse-antifuse structure comprises a horizontal B-fuse portion and a vertical A-fuse portion disposed between two metallization layers of an integrated circuit device. The two-terminal fuse-antifuse can be programmed with a relatively high current applied across the two terminals to blow the B-fuse, or with a high voltage applied across the two terminals to program the A-fuse. Such a device, connected between two circuit nodes, initially does not provide an electrical connection between the two circuit nodes. It may then be programmed with a relatively high voltage to blow the A-fuse, causing it to conduct between the two circuit nodes. Then, upon application of a relatively high current between the two circuit nodes, the B-fuse will blow, making the device permanently non-conductive. An improvement permitting higher current programming of B-fuses either alone or as part of Ab-fuse structures, incorporates an air gap which provides a pocket of space either above, below or both above and below the B-fuse portion of the device. This air gap provides a place for material disrupted (melted or vaporized) by a fuse or Ab-fuse programming event to go, eliminates direct contact between the dielectric material and the fuse-portion of the device, and also thermally isolates the melted fuse material from the dielectric, thus reducing the physical stress within the dielectric itself associated with high current programming and avoiding undesired collateral damage normally associated with high current programming events. The creation of an air gap around the fuse neck is accomplished by the removal of a sacrificial layer of an oxidizable polymer material in a gaseous and/or plasma state through a small hole in the dielectric referred to as a sacrificial via opening or just "sacrificial via". After removal of the oxidizable polymer material through the sacrificial via, the sacrificial via is sealed with a passivation layer formed of a polymeric material to prevent damage to the underlying structure. The integration of the air gap and sacrificial via sealing into the current fuse process manufacturing requires the following additional processing steps: (1) Air gap definition; (2) Air gap evacuation with oxygen plasma; (3) the application of the sealing polymer; and (4) the curing of the sealing polymer.

    • A type of piezoelectric transformer (PT) which vibrates in length extensional mode is provided. The piezoelectric transformer (PT) has a piezoelectric substrate which has a first dimension, a second dimension and a third dimension with the first dimension being longest and the third dimension being shortest. The substrate has two polarization directions parallel to the first dimension near two terminals of the first dimension and at least two opposite polarization directions on a central portion of the substrate transversely to the first dimension. The substrate further has at least two electrodes on a portion horizontal to the first dimension. Comparing with traditional piezoelectric transformers, the new one can solve the polarization difficulties and reduce audio noise output without sacrificing the electrical properties or even have better voltage transformation characteristics.

    • A piezoelectric composite receiver for use in telephones comprising a front cover, a rear cover, and a transducer plate, which is provided with an piezoelectric layer so as to provide the function of an electroacoustic transducer. Each of the front cover and the rear cover has an elliptically-shaped protrusion for clamping the transducer plate therebetween. The elliptically-shaped protrusions allows the transducer plate to freely vibrate in the frequency range of interest (i.e., between 300 Hz and 3,400 Hz), while the sound in the high frequency region (above 3,400 Hz) is effectively suppressed. The front cover and the rear cover are made of a plastic material using an injection molding process, and either the front cover or the rear cover, or both, are provided with an ultrasonic welding loop, which allows the receiver to be affixed using an ultrasound welding device. An induction coil can be imbedded in the outer periphery or an upper portion of the front cover which can be coupled to a hearing aid so as to allow an hearing impaired to utilize a telephone which utilizes the piezoelectric composite receiver.
