摘要： A radio frequency identification (RFID) tag on a single layer substrate comprises a semiconductor integrated circuit RFID tag device and antenna circuit. A connection jumper may be used to bridge over the antenna circuit coil turns. The RFID tag device is located on the same side as an inductor coil and capacitor which forms a parallel resonant antenna circuit. The inductor coil has an inner end and an outer end. The inner or outer end may be connected directly to the RFID tag device and the outer or inner end be may connected to the RFID tag device with a jumper over the inductor coil turns, or the RFID tag device may bridge the inductor coil turns when being connected to both the inner and outer ends. An encapsulation (glop top) may be used to seal the RFID tag device and jumper, and an insulated coating may be used to cover the entire surface of the substrate to create an inexpensive “chip-on-tag.” The encapsulation may be epoxy, plastic or any protective material known to one of ordinary skill in the art of electronic circuit encapsulation. The insulated coating may be of any type suitable for the application of use of the RFID tag.

摘要： A wireless tire inflation pressure measurement device is used to obtain inflation pressure information for a tire of a vehicle and a signal therefrom may be used for determining the location of the tire. An identifier may be associated with the inflation pressure information for each wheel of the vehicle. Tire rotation speed may be determined by amplitude fluctuations of a radio frequency carrier from a radio frequency transmitter rotating with the wheel. Differences in wheel rotation speeds during a turn may be used in determining the location of each tire of the vehicle. An antenna may be placed on each wheel toward the outer perimeter of the wheel and connected to the radio frequency transmitter. A radio frequency identification (RFID) tag and pressure sensor may be used as the wireless tire inflation pressure measurement device and a RFID pickup coil may be provided in each wheel well for pickup of the inflation pressure signals from each RFID tag on a wheel.

摘要： An improved high quality factor capacitive device is implemented on a single, monolithic integrated circuit. The new layout techniques improve the quality factor (Q) of the capacitor by reducing intrinsic resistance of the capacitor by reducing the distance between the metal contacts of the top and bottom conductive plates. The layout techniques require laying out the top conductive plate of the capacitor in strips such that metal contacts from the bottom conductive plate pass in between the strips and through the dielectric layer. Alternatively, the apertures may be etched into the top conductive plate so that metal contacts pass through the apertures and connect to the bottom conductive plate.

摘要： A method is disclosed for forming narrow thermal silicon dioxide side isolation regions in a semiconductor substrate and MOS or CMOS semiconductor devices fabricated by this method. A thin stress relief layer is used in conjunction with a polysilicon buffering stress relief layer on the surface of a semiconductor substrate prior to the field oxidation process to restrict lateral silicon dioxide expansion thereby permitting the creation of narrow thermal silicon dioxide side isolation regions in the semiconductor substrate. A silicon dioxide layer is also used between an amorphous polysilicon (buffering stress relief) layer and a silicon nitride layer to function as an oxide cap, to avoid undesired pitting of the amorphous polysilicon layer, and to avoid interaction between the silicon nitride and amorphous polysilicon layers in areas of high stress.
