China’s push for semiconductor self-sufficiency has boosted Hubei Dinglong, a key supplier of chip-making materials, reports Forbes. The company produces CMP materials, photoresists, and advanced packaging chemicals used in semiconductor manufacturing.
Strong demand and expansion in these businesses have driven rapid growth in Dinglong’s revenue and share price, turning its founders into billionaires as the firm benefits from China’s drive to reduce reliance on foreign chip technology. They write:
China’s push for self-sufficiency in semiconductor manufacturing has benefited companies across the supply chain. […]
Since the U.S. imposed chip-related export controls on China in 2022, Dinglong has expanded into materials for lithography, a major hurdle for China’s self-reliance in semiconductors where ultraviolet light is used to print circuits onto silicon wafers. In lithography, Dinglong manufactures photoresist, a chemical that captures the circuit design, though its most advanced products can only be used in lower-end chip manufacturing. […]
