Nanoprinting lithography shifts from round to square, increasing waveguide output

The shift from circular to square substrates in nanoprinting lithography signals a move toward higher throughput and larger template compatibility. This evolution will drive upstream advancements in photoresist and template manufacturing, while enhancing downstream waveguide and photonic integration efficiency. From a compliance standpoint, this transition may trigger global supply chain realignment, especially under import restrictions on critical materials and equipment. Competitors are likely to accelerate investments in square substrate technologies to gain market dominance in photonic chips. Within the next 12 months, this shift will accelerate commercialization of photonic integrated circuits, particularly in data center and 5G/6G communication sectors. If production capacity in Taiwan, China and Hong Kong, China fails to scale accordingly, global photonic chip supply chains may face structural disruptions.
