The invention comprises a method and apparatus for enabling a subscriber to establish a call to at least one destination phone number using an email address. Implanted halo, LDD andor SD source and drain regions formed by angled subimplants may have different extents of overlap with, or lateral separation from, gates of the two types of transistors, producing transistors with two different sets of electrical properties. The drive unit presses the probe pin to the calculated central coordinates of the inspection pad to perform inspection.
