The present invention provide a wafer level chip size packaged chip device with a N-shape junction at which external leads electrically connect to peripheral arrayed compatible pads and a method of fabricating the same. In the wafer level chip size package, with such an n-shape junction instead of a conventional T-shape junction observed in Shellcase type wafer level chip size package technology, electrical connections between compatible pads and external leads are more reliable due to larger connection area than the counterpart in the T-shape junction.
