Lithography machine is the most core equipment for manufacturing chips, and all chips need to be made by lithography mechanism. Our country can independently produce chips, but the yield is relatively low, resulting in the cost of manufacturing prices will be much higher than the cost of other countries, high costs represent no market, so the mobile phone manufacturing industry will be choked.
But the military chip is different, the army is the embodiment of a country's comprehensive strength, we invest a lot of money to the army, do not need to consider the cost and market, so our country's military chip is independently produced, and the quality is particularly good.
