How To Build Billions of Bumps

Hybrid bonding technology is ushering in a new era of interconnects in the semiconductor industry, enabling billions or even trillions of connections per chip. By bonding chips and interposers at pitc... Read original →

Hybrid bonding has transcended packaging to become a foundational architectural constraint. Sub-micron pitch interconnects are forcing a complete re-engineering of CMP and dielectric stacks—making Lam Research’s planarization tools and Brewer Science’s ultra-low-k materials critical yield determinants. Synopsys must embed physical verification deep into chiplet design flows; otherwise, signal integrity collapse will nullify HBM4’s bandwidth gains. Geopolitically, the technology’s reliance on EUV exposes Taiwan, China and mainland Chinese foundries to asymmetric cost risks under export controls, while European equipment makers like EV Group solidify their indispensability. Within 18 months, the industry will pivot toward testability-by-design, sidelining second-tier OSATs that can’t achieve wafer-level process uniformity from AI chip supply chains.
