TOKYO -- Fujifilm Holdings and Sumitomo Chemical will each start supplying a material used in next-generation chipmaking as early as 2021, which could help make smartphones and other devices smaller and more energy-efficient.

The two Japanese companies are working on special photoresists used in extreme-ultraviolet lithography, where complex circuits are patterned with a special light. Light-sensitive photoresists serve as the coating for this patterning process.
