Essential material for advanced semiconductor processes expected to enter stage of accelerated breakthroughs, major Chinese supplier says.

China’s push for semiconductor self-sufficiency is shifting from broad aspiration to a precision strike on chokepoint materials, with photoresist – the light-sensitive chemical essential for etching microscopic circuits onto silicon wafers – emerging as a new battlefield. The sector, which provides the key material for lithography, was expected to enter a critical stage of “accelerated breakthroughs and large-scale application” over the coming years, according to Fu Zhiwei, chairman of Xuzhou…
