Intel advances chip designs as equipment shortages constrain growth

Intel is developing new manufacturing and packaging technologies to meet surging AI demand, while warning that equipment shortages constrain industry expansion. Its next manufacturing process, 14A, is due in roughly two to three years. The process combines gate-all-around transistors, High-NA EUV lithography and backside power delivery to improve density and simplify the printing of intricate chip patterns.

Moving power wiring behind the wafer frees space for signal connections, helping Intel use a single High-NA printing pass where tighter layouts would otherwise require multiple passes. Further ahead, CFET designs would stack complementary transistor types vertically to increase density, although removing heat remains a major obstacle. Researchers are also exploring ruthenium for the finest wiring, while hybrid bonding connects finished chips directly through copper connections without bulky solder bumps.

Manufacturing capacity depends on more than better designs. ASML produces fewer than 100 EUV lithography machines a year and has no plans to significantly exceed that output by the end of the decade. Intel expects to reuse about 80% of its existing tool set when moving from 18A to 14A. With top-end equipment lead times of about 18 months, Intel CTO Pushkar Ronde says production is unlikely to meaningfully exceed expectations by 2030 unless toolmakers and their suppliers expand together.
