# Corrosion in Microelectronics Packages

## Abstract

The potential for failure in a microelectronic device due to corrosion has increased as the device metallization tracks have become narrower and thinner, the separation between metallization tracks has become closer, and bond pads have become smaller. Although corrosion problems are well documented in the literature and preventive measures are known, corrosion failures continue to occur. About 20% of electronic failures are caused by corrosion.^{1,2} Most of the problems result from a violation of one or more of the fundamental design or corrosion-prevention guidelines, caused by improper material selection, improper design of geometry, or inadequate control of the manufacturing and assembly processes.
