Huawei produced its revolutionary chip with technology from two American providers, even with Biden's restrictive measures in place

Huawei and SMIC astonished the global community when the Chinese cell phone firm introduced the Mate 60 Pro with a state-of-the-art 7nm chip. Due to sanctions imposed by the United States, chip creation has been risky in China for a long time.

Sources with knowledge of the situation disclosed that Huawei and its associate, Semiconductor Manufacturing International Corp (SMIC), relied significantly on American technology to develop a sophisticated chip in China the previous year.

Based on information from unnamed insiders, Shanghai's SMIC leveraged technology from Applied Materials Inc. and Lam Research Corp., both California companies, to create an advanced 7nm chip for Huawei in 2023. These informants wished to remain anonymous because the specifics are not public knowledge.

The concealed data highlights China's continuous dependence on foreign parts and machinery for sophisticated products like semiconductors. Even though China has emphasized on becoming technologically independent, it still leans on international supplies for some essential technologies. Beijing has backed Huawei's efforts to improve local chip design and manufacturing.

Spokespeople from SMIC, Huawei, and Lam chose not to give any statements regarding the issue. Applied Materials, along with the US Commerce Department's Bureau of Industry and Security, who oversee export controls, also abstained from offering any remarks.

Despite being praised as a major milestone in China's semiconductor progress, the chip made by SMIC last year for Huawei's Mate 60 Pro triggered a rise in nationalistic smartphone buying in the nation. Even though the chip doesn't quite meet global benchmarks, it signifies an advancement that exceeds US expectations to limit China's technological growth.

Nonetheless, the apparatus utilized in its creation still depended on international suppliers, such as technology from the Dutch company ASML Holding, and machinery from Lam and Applied Materials.

Top Chinese chip equipment manufacturers are making efforts to match the standards of their American competitors, but their products still lack the broad range and complexity. Despite their best attempts, Shanghai Micro Electronics Equipment Group Co., China's leading lithography system developer, still lags behind the industry frontrunner, ASML.

SMIC managed to buy the American equipment prior to the US enforcing restrictions in October 2022. After the prohibition was put into effect, American vendors pulled out their personnel from China, and ASML forbade its US workers from collaborating with Chinese clients.

The US has subsequently enforced additional limitations, banning the distribution of advanced, US-based technology to SMIC and Huawei, both of which are blacklisted due to purported connections with the Chinese military.

The imposition of these trade restrictions led Huawei and SMIC to explore other options for establishing a local chip supply chain, eventually resulting in the launch of the Mate 60 Pro.

As a reaction, the US started a probe into Huawei's processor, with Commerce Secretary Gina Raimondo promising strict measures for national security. Republican legislators have suggested totally barring Huawei and SMIC from US technology.

Trade authorities question whether SMIC can manufacture 7nm chips on a large scale without the aid of ASML's lithography systems, emphasizing the technical difficulties and possible constraints on chip production capacity.

The United States is encouraging its allies to intensify limitations on China's access to semiconductors, even though some nations are hesitant due to the potential impact on trade.

Huawei is surfacing as a possible competitor in China's chase for AI chip advancement, presenting a threat to dominant players such as NVIDIA, as stated by CEO Jensen Huang.

While China progresses in technology amidst worldwide observation, its dependence on overseas technology highlights the intricacies of global commerce and issues of national security.
