Sapphire supports optical devices through its wide transmission range, high hardness, thermal stability, and resistance to chemical attack. Synthetic sapphire is a single-crystal form of aluminum oxide that can function as both an optical transmission medium and a protective structural component.
Glass materials used for TGV must support precise via formation, stable metallization, low electrical loss, and reliable thermal cycling. Borosilicate glass, alkali-free glass, fused silica, and other engineered glass compositions can all be considered, but their coefficients of thermal expansion, dielectric properties, thickness, and laser response are different.
Reducing wafer processing defects requires control from raw-material selection through cutting, grinding, polishing, cleaning, inspection, and packaging. Defects rarely come from one isolated operation. Scratches, pits, particles, chips, thickness variation, bow, and subsurface cracks often develop through several connected process conditions.
