Gold-Nickel Lidseal Process Improvement (Hydrogen
suggests a method for improving the lidseal bond
using silver glass die attach materials.
die attach materials require high curing
temperatures to 410@C in air to drive off the organic components
present in the die attach materials. Unfortunately, this results in a
substantial amount of Ni out diffusion and oxidation at the seal
problems can be eliminated by performing a preclean
operation in a reducing atmosphere of 100% hydrogen prior to the
lidseal operation. A peak temperature of
330@C with a dwell time of
8 minutes above 280@C has been used successfully.
