What Is Antenna Effect? |
|
Answer» The antenna effect, more formally plasma INDUCED gate OXIDE damage, is an efffect that can potentially cause yield and reliability problems during the manufacture of MOS integrated circuits. Fabs normally SUPPLY antenna rules, which are rules that must be obeyed to avoid this problem. A violation of such rules is called an antenna violation. The word antenna is somewhat of a misnomer in this CONTEXT—the problem is really the collection of charge, not the normal meaning of antenna, which is a device for converting electromagnetic fields to/from electrical currents. Occasionally the phrase antenna effect is USED this context[6] but this is less common since there are many effects[7] and the phrase does not make clear which is meant.
