Liyan chips are inspection chips, not production chips.
The so-called Liyang chip production of 3nm chips is actually for Samsung's chips to do technical testing, not Liyang chip production of its own chips. Liyang chip business is mainly in the field of integrated circuit testing, providing independent third-party testing technology services for middle and high-end chips for well-known chip design companies at home and abroad. The products are mainly used in communication, computer, consumer electronics, automotive electronics and industrial control and other fields, and the process covers 8nm, 16nm, 28nm and other advanced processes. Therefore, Liyang chip does not have a lithography machine, does not produce 3nm chips, and only does testing on sample chips provided by chip manufacturers.
