Sodium silicate as an enabler for wafer bonding of glass substrates and lids

Research output: Chapter in Book/Report/Conference proceedingsChapterpeer-review

Abstract

The outgassing challenge associated with using polymer-based die-attach adhesives for vacuum seal photonic packages is addressed in this extended abstract. In addition to this, die movement can occur after high temperature anodic bonding of the lid/cap wafer and substrate wafer due to low glass transition temperature of polymer based adhesive systems. This presents a challenge for photonic packages where photonic chip's positional accuracy is critical. Silicate based adhesives are presented as a solution to enable vacuum seal packaging of photonic chips.
