The chips in greatest demand are those near the 55nm process.
From the actual situation, most of the current electronic products on the chip process requirements are not so tall, most electronic products only need 28 nm to 90 nm between the chip can be competent, really need more than 14 nm chip support, mainly some consumer terminal electronic products, such as mobile phones. Professor Wu Minghan, an academician of the Chinese Academy of Engineering, believes that at present, what China needs to solve most is not a 7 nanometer or more advanced chip, but a 55 nanometer chip process.
At present, the mainstream of mobile phone chips is 7nm and 5nm, and the mainstream of automotive chips is 28nm.
