SMIC first started volume production of chips using its 14 nm FinFET fabrication process in Q4 2019. Since then, the company has been hard at work developing its next generation major node, which it's calling N+1. The technology has certain features that are comparable to competing 7 nm process technologies, but SMIC wants to make it clear that N+1 is not a 7 nm technology.

When compared to SMIC’s 14 nm process technology, N+1 lowers power consumption by 57%, increases performance by 20%, and reduces logic area by up to 63%. While the process enables chip designers to make their SoCs smaller and more power efficient, its modest performance gains do not allow N+1 to compete against competitors' 7 nm technology and derivatives. To that end, SMIC positions its N+1 as a technology for inexpensive chips.
