  • Publication number: 20150069578
    Abstract: Consistent with an example embodiment, there is a method for preparing integrated circuit (IC) device die from a wafer substrate having a front-side with active devices and a back-side. The method comprises pre-grinding the backside of a wafer substrate to a thickness. The front-side of the wafer is mounted onto a protective foil. A laser is applied to the backside of the wafer, at first focus depth to define a secondary modification zone in saw lanes. To the backside of the wafer, a second laser process is applied, at a second focus depth shallower than that of the first focus depth, in the saw lanes to define a main modification zone, the secondary modification defined at a pre-determined location within active device boundaries, the active device boundaries defining an active device area. The backside of the wafer is ground down to a depth so as to remove the main modification zone. The IC device die are separated from one another by stretching the protective foil.

  • Publication number: 20150072617
    Abstract: Wireless data communication is implemented using respective carrier frequencies. As may be implemented in accordance with one or more embodiments and apparatuses herein, wireless communications are effected using a resonant circuit having a resonant frequency susceptible to detuning. Radio frequency power is transmitted to a remote transponder circuit, and wireless communications are effected with the remote transponder circuit via at least one of first and second different carrier frequencies, using the resonant circuit and the radio frequency power. The first and second carrier frequencies are respectively sufficiently proximate to the resonant frequency, such that signals communicated based on the resonant frequency can be acquired by demodulating based on the resonant frequency. One of the first and second carrier frequencies is selected based upon a signal sent from the transponder circuit.

As consistent with one or more embodiments, bits corresponding to a circuit component of a circuit design are evaluated using a software program that characterizes a hardware description language representing the circuit components and their interconnectivity. A noise power value is calculated for each bit, and bits are identified as being susceptible to data error based upon the noise power value and a signal-to-noise (SNR) ratio reference value. A characterization of the circuit components (e.g., a quality factor) is provided based upon a number of bits susceptible to data errors.
