DARPA-funded GaN/InP-CMOS heterogeneous integration limited to defense giants

Only major defense contractors can heterogeneously integrate GaN HEMTs and InP HBTs with wafer-scale CMOS under DARPA funding, while TSMC and Intel each hold only part of the process pie. Industry discussion also highlights turnaround time and process touch count as the real bottlenecks in advanced packaging.
