Photoresist Localization Accelerates, China Semiconductor Materials Supply Chain Takes Key Step Toward Self-Sufficiency

Semiconductor Materials Localization Enters Deep Waters

Against the backdrop of global semiconductor supply chain restructuring, China semiconductor materials localization process is accelerating. Photoresist, as one of the core materials in semiconductor manufacturing, its localization breakthrough is of great significance for supply chain security.

KrF Photoresist Mass Production Breakthrough

Shanghai Sinyang, Jinhong Gas and other Chinese companies have achieved mass production breakthroughs in KrF photoresist, with products passing verification at multiple wafer fabs and achieving bulk supply. The improvement in KrF photoresist localization rate effectively reduces China semiconductor manufacturing dependence on imported materials.

ArF Photoresist R&D Progress

In the higher-end ArF photoresist field, companies like Nanda Optoelectronics and Shanghai Sinyang are actively promoting R&D and customer verification. ArF photoresist has higher technical barriers, but the prospects for domestic substitution are broad.
