The authorisation extended the company's design work from 16 nm and 12 nm FinFET to 7 nm.
In 2019 Chipchain was authorised to use TSMC's 7 nm FinFET design materials.
Design materials are what a chip is designed against: the foundry's rules, device models and libraries.
The authorisation followed the company's access to 16 nm FinFET and to the 12 nm FinFET design kit, both in 2018.
Chipchain is a fabless AI chip company based in Shenzhen and a TSMC direct account. It designs application-specific AI chips, from architecture through tape-out to production.
