Abstract
A semiconductor die is attached to a substrate by a glass frit layer. Gas that might be trapped between the die and the glass frit layer during firing of the glass frit can escape through passages that are formed against the bottom surface of the die by topographies that extend away from and which are substantially orthogonal to the bottom of the die.
