Semiconductor Manufacturing International Corp (SMIC) extended a manufacturing equipment purchase deal with Netherlands-based ASML, giving the Shanghai-headquartered company more time to beef up its production capacity in the face of US trade sanctions.

In a statement on 3 March, ASML explained an existing three-year agreement for deep ultraviolet (DUV) lithography technology which commenced in January 2018 had been extended to the end of 2021. It added the amendment was signed off in February, but SMIC had only just informed the Hong Kong Stock Exchange.

Between 16 March 2020 and 2 March 2021, SMIC purchased equipment valued at $1.2 billion, it added.

The agreement doesn’t over ASML’s extreme ultraviolet lithography equipment (EUV), which is used to produce the latest generation of chips: South China Morning Post reported the company applied for a licence from the Netherlands government covering exports to China. The nation accounted for 18 per cent of AMSL’s €10.3 billion in equipment sales in 2020.

On an earnings call last month, SMIC co-CEO Zhao Haijun said it will continue to add production capacity this year to match strong demand. It expects revenue growth, assuming there is no significant adverse impact on operations from US sanctions.

In early December 2020, SMIC was added to a list of companies US investors are prohibited from buying securities in, which added to a previous US government move covering exports of some equipment to the chipmaker.
