Abstract
A barrier or 'crackstop' that is configured to conduct electrical signals. These configurations may form a wall around integrated, active circuitry of a semiconductor die. This wall may include a conductor that follows a three-dimensional pathway from one side to the other side of the wall. This pathway may have sections that overlap, or double-back, so that portions of the conductor overlap along their individual length. These sections prevent crack propagation internal to the wall.
