A Comprehensive Analysis of CPO Coating Coatings
A Comprehensive Analysis of CPO Coating Coatings A Comprehensive Analysis of CPO Coating Coatings: Material System and Core Functions In CPO (Co-Packaged Optics) co-packaging, coatings are applied to the substrate, chip surface, and optical interface to form a multi-layered composite protection and functional enhancement system. Core Coating Types and Materials Passivation/Insulating Coatings Silicon Dioxide (SiO₂): CVD/PVD deposition, 0.1–2 μm thick, provides insulation and moisture barrier. Silicon Nitride (Si₃N₄): Covers the [...]
