The invention includes semiconductor constructions containing vertically-extending pillars, and methods for forming such constructions. A receiver has an antenna that detects a signal radiated by the probe and has receiver circuitry that detects the deviation from the received signal. The sound signal is then coded using the enhanced first part of the sound signal and the enhanced first part of the sound signal and the enhanced sound part of the sound signal. The case includes a communications link for establishing communication between the controller of the pen and the controller of the monitor. The capabilities may include the device type, applications, programs, or services that the user of the device is subscribed to, or capabilities that are inherent to the phone. The invention also provides a shield at floating potential, restricting the cathode spot from migrating into selected regions of the target evaporation surface outside of the desired erosion zone.
