Abstract
Electronic packages made with a high area percent coverage of blanket metal may be prone to certain kinds of ceramic defects. In aluminum nitride, these defects may be related to decomposition of the liquid sintering aid. In this experiment, unique additions to the metallization prevented the formation of certain ceramic defects. Our approach involves a unique composition used in an existing process.
