Chinese phone maker Huawei announced it has released its self developed phone chip, the advanced Kirin 980,  the world’s first mobile chip using TSMC’s 7nm process, The Paper reported.

Huawei representative Ai Wei said the company has invested more than US$300 million in the R&D of the chip, which was launched in Shanghai.

For mobile phone chips, advanced manufacturing processes are the foundation for performance and power efficiency. At present, the industry generally adopts the 10nm process, while Apple as well as Qualcomm’s next-generation chip are also expected to adopt the 7 nm process.

So far, TSMC, known as the Taiwan Semiconductor Manufacturing Company, the world’s largest dedicated independent semiconductor foundry, is the only company in the world that supports mass production of the 7nm process.

Huawei’s flagship mobile phone Mate20 series to be released next month will be equipped with this chip.
