Abstract
A semiconductor die is enveloped by an ambient gas that will react to the presence of a particular wave length of light. A laser beam is focused on the edge of the die to deposit a dielectric coating. The laser beam or the die is rotated until the dielectric coating covers the entire die edge. The dielectric coating acts as a seal that is impervious to water and other contamination that can reduce the die reliability. The dielectric coating also electrically insulates the die from its surroundings.
