Huawei recently released a new smartphone, the Mate 60 Pro, which appears to incorporate technologies that the company should not have access to. In Washington, the question arises as to whether the manufacturer has circumvented sanctions on the export of technologies or worse, whether China has managed to create its own processors without the help of American technologies.

Logically, Huawei’s new Mate 60 Pro smartphone should not exist. And yet… The Chinese manufacturer is subject to American sanctions, in other words no company in the world has the right to sell it components if they are based on American technologies, which should have prevented the creation of this smartphone .
Huawei has been reluctant to communicate the technical details of its device. However, the Canadian site TechInsights disassembled the smartphone to identify the components. The majority of elements appear to have been designed and produced in China, but the Mate 60 Pro still has some anomalies.
American technology and South Korean chips
One of the surprises is the Kirin 9000s chip, engraved in 7 nm and which supports 5G, two technologies to which Huawei should not have access, raising many questions within the American government. The chip is produced by SMIC (Semiconductor International Manufacturing Corp), also under US sanctions and therefore should not have access to the necessary extreme ultraviolet (EUV) lithography machines. Note that this is a technology that is still 5 years late, Qualcomm, Apple and MediaTek being in the process of moving from 4 nm to 3 nm.
The smartphone also contains LPDDR5 RAM and NAND Flash storage chips from South Korean manufacturer SK Hynix. The firm announced that it is scrupulously respecting American sanctions and indicates that it has launched an internal investigation to understand how its components could have been used by Huawei, but some suggest that it could be stock purchased in 2020.
