What chip concept stocks are there?

Samsung Electronics pioneered the mass production era of "10 nanometer DRAM" (Dynamic Random Access Memory) in the world. Samsung Electronics announced on the 5th that since February this year, the world's smallest 10 nanometer (18 nanometer) 8GB DDR4 (double data rate 4)DRAM has entered commercial production. At present, other competitors are still at the level of producing 25-30 nm DRAM, and have just started mass production of 20 nm products. With the centralized support of China government, China semiconductor enterprises have been timidly catching up with Korean enterprises. Samsung's move highlights its technological advantages, but China enterprises will certainly catch up.
