China's homegrown DUV tools being delivered to SMIC give it an alternative to ASML-dominated lithography supply.
“The machines are expected to be delivered this year to leading Chinese chipmakers, including Semiconductor Manufacturing International Corp, Hua Hong Semiconductor and ChangXin Memory Technologies.”
