No, the RF chip (such as the antenna, etc.) of the Mate 60 Pro 5G is not made by the lithography mechanism. Lithography machines are mainly used to manufacture micrography technology in integrated circuits (ics), while RF chip manufacturing usually uses other processes, such as metal deposition, evaporation, etc. Rf chips use materials such as metal layers and dielectric layers in the manufacturing process to achieve wireless communication and signal processing functions.
