Suzhou Zhicai Ships 6-Inch MRAM-Grade MgO Target, Closing the Last Foreign-Controlled Gap in China’s MRAM Material Stack

Suzhou Zhicai Technology has developed a 6-inch high-purity high-density magnesium-oxide sputtering target qualified for MRAM magnetic tunnel junction production, with purity of 4N and density above 99.8 percent. The breakthrough completes China's domestic supply for the full MRAM target material stack and removes the last overseas-controlled bottleneck in the country's MRAM pilot lines.
