An identification method and identification device are presented employing radio frequency and acoustic wave communication modes. The identification method includes: receiving at an acoustic wave and radio frequency identification device an acoustic wave signal of a first frequency and a radio frequency signal of a second frequency, where the acoustic wave signal and the radio frequency signal are received from an acoustic wave and radio frequency identification reader, and the first frequency and the second frequency are different frequencies; and responding to the receiving by transmitting at least one of an acoustic wave identification (AWID) or a radio frequency identification (RFID) from the acoustic wave and radio frequency identification device.

Circuits and methods are provided for facilitating transitioning of a digital circuit from backgate biased standby mode to active mode. The digital circuit includes a semiconductor substrate, multiple n-channel transistors disposed at least partially in one or more p-type wells in the semiconductor substrate, multiple p-channel transistors disposed at least partially in one or more n-type wells in the semiconductor substrate, and a backgate control circuit. The backgate control circuit is electrically coupled to the p-type well(s) and to the n-type well(s) to facilitate transitioning of the multiple n-channel transistors and the multiple p-channel transistors from backgate biased standby mode to active mode by automatically shunting charge from the n-type well(s) to the p-type well(s) until a well voltage threshold is reached indicative of a completed transition of the transistors from backgate biased standby mode to active mode.

Back-end-of-line (BEOL) circuit structures and methods are provided for blocking externally-originating or internally-originating electromagnetic edge interference. One such BEOL circuit structure includes a semiconductor substrate supporting one or more integrated circuits, and multiple BEOL layers disposed over the semiconductor substrate. The multiple BEOL layers extend to an edge of the circuit structure and include at least one vertically-extending conductive pattern disposed adjacent to the edge of the circuit structure. The vertically-extending conductive pattern is defined, at least partially, by a plurality of elements disposed in the multiple BEOL layers. The plurality of elements are uniformly arrayed at the edge of the circuit structure in a first direction or a second direction throughout at least a portion thereof. The plurality of elements are sized and positioned in the first direction or the second direction to block electromagnetic interference of a particular wavelength from passing therethrough.

An apparatus and method for recycling and reusing charge in an electronic circuit. The apparatus includes at least one capacitor coupled to a circuit block in the electronic circuit, the capacitor being configured to collect current charge consumed by the circuit block when set to a charge collection mode, and a voltage level comparator configured to detect a fully charged state when the capacitor is fully charged. Further, the apparatus includes a first electrical switch configured to allow, once the fully charged state is detected, the capacitor to switch to a discharge mode for discharging the current charge collected back into the power supply for reuse by the electrical system and a second switch configured to allow, after the capacitor has fully discharged the current charge collected, the capacitor to switch back to the charge collection mode, such that, the current charge is recycled and reused by the electrical system.

Back end of line (BEOL) circuit structures and methods are provided for blocking externally-originating or internally-originating electromagnetic interference. One such BEOL circuit structure includes one or more semiconductor substrates supporting one or more integrated circuits, and one or more BEOL layers disposed over the semiconductor substrate(s). At least one BEOL layer includes a conductive pattern defined at least partially by a plurality of elements arrayed in a first direction and a second direction throughout at least a portion thereof. The plurality of elements are sized and positioned in at least one of the first and second directions to block electromagnetic interference of a particular wavelength from passing therethrough. In one implementation, a first conductive pattern of a first BEOL layer polarizes electromagnetic interference, and a second conductive pattern of a second BEOL layer blocks the polarized electromagnetic interference.

Sub-100 nanometer semiconductor devices and methods and program products for manufacturing devices are provided, in particular inductors comprising a plurality of spaced parallel metal lines disposed on a dielectric surface and each having width, heights, spacing and cross-sectional areas determined as a function of Design Rule Check rules. For one planarization process rule a metal density ratio of 80% metal to 20% dielectric surface is determined and produced. In one example a sum of metal line spacing gaps is less than a sum of metal line interior sidewall heights. In one aspect at least one of line height, width and line spacing dimensions is selected to optimize one or more chip yield, chip performance, chip manufacturability and inductor Q factor parameters.
