Abstract
Method and apparatus are disclosed for protection of a circuit against process-induced electrical discharge. The method includes forming a diode in close proximity to a charge collector structure capable of exhibiting the antenna effect, and connecting the diode to the charge collector structure by means of local interconnect techniques during intermediate processing steps. Additionally, the diode may be formed beneath a connecting pad to reduce or eliminate antenna effect problems without significant loss of die area.
