Industry Analysis
The AI infrastructure surge is triggering structural shortages in the semiconductor physical layer—particularly in high-speed interconnects and advanced packaging. Microchip’s early PCIe Gen6 retimer wins alleviate signal integrity bottlenecks in CXL ecosystems but simultaneously pressure upstream OSATs to accelerate CoWoS-like capacity. Escalating U.S. export controls, however, inflate compliance costs and elongate lead times for U.S. firms reliant on foundries in Taiwan, China. While TI and Vishay dominate power delivery, their data center foothold risks erosion by Renesas and Infineon without regionalized, redundant supply chains. Over the next 18 months, optical DSPs and transimpedance amplifiers will become decisive battlegrounds for 800G/1.6T optical module upgrades, while Amtech benefits from surging capex in localized advanced packaging lines. The AI hardware race has evolved beyond raw compute—it’s now a contest of connection density and power efficiency at the silicon-package interface.
