5nm chip mass production is not real.
< br >
Because of well-known reasons, the United States restricts Huawei's use of high-end chips and does not allow the use of chips produced by lithography machines containing American technology to supply Huawei, so Huawei cannot use 5G chips for the time being. For Huawei, which has the most 5G patents, this is indeed a great irony, but we believe that the difficulties are only temporary, and it will not be long before Huawei chips will return.
