Samsung plans to release smartphones and other device chips based on the 5nm process next year
Samsung has already begun mass production of chip products based on the 7nm process, but the company has also decided to start using the 5nm process next year. Samsung said it has begun small-scale testing of 5nm process chips and also uses EUV (extreme ultraviolet) technology currently on the 7nm process. Interestingly, the company also announced that the EUV lithography line for manufacturing 7-nanometer chips cost $6 billion, and it can be seen that the initial investment is very high.
