Advanced Packaging Materials Grow Faster Than Front-End
Chiplet architectures and high-bandwidth memory stacking have made packaging a performance-determining step rather than an afterthought, and the materials required differ completely from wafer fabrication. Organic substrates, underfills, thermal interface materials and hybrid bonding chemistries now account for roughly 26% of materials value against a considerably smaller share five years ago. The supplier base differs too, drawn from printed circuit board and adhesive companies rather than from wafer chemical producers, which has brought participants into semiconductor supply chains who were never previously part of them and who bring quite different commercial habits.
