As the chip industry develops more sophisticated processors with higher heat dissipation requirements, some firms have moved on to chiplet-based designs. This not-so-gradual shift has resulted in chip packaging technologies becoming increasingly important. Large and highly complex chips such as Nvidia's H100 and advanced multi-chip solutions like Intel's Data Center Max GPU (Ponte Vecchio) present new requirements for packaging materials. To that end, Dai Nippon Printing (DNP) is showcasing a new development for semiconductor packages – Glass Core Substrate (GCS) – which it says can address many of those challenges. Typically, modern chips are installed on fine pitch substrates (FPS), which are then put on multi-layer high-density interconnect (HDI) substrates. The most advanced CPU/GPU HDI substrates these days use Ajinomoto Build-up Film(ABF), which combines organic...
