7 nm lithography process

The 7 nanometer (7 nm) lithography process is a full node semiconductor manufacturing process following the 10 nm process node. The term "7 nm" is simply a commercial name for a generation of a certain size and its technology, as opposed to gate length or half pitch. Commercial mass production of integrated circuit using 7 nm process is set to begin sometimes in 2019 or 2020. This technology will be replaced by 5 nm process around 2022.

Industry[edit]

In ISSCC 2017, the memory group at TSMC detailed their test 128 MiB SRAM chip which featured a 42.7 mm² die (measuring 5903µm x 7233µm[1]). The chip is manufactured on TSMC's 7nm HK-MG FinFET process. The chip, which initially debuted in last year's ISSCC, makes use of 0.027 µm² bit cells, currently the smallest such cells in risk production. The over die is 0.34x smaller than their 16 nm process version. At the same conference, Samsung detailed limited use for EUV in their 7nm node, though not much more is known. On February 8 2017 Intel announced a $7B investment in Arizona's Fab 42 which will eventually produce chips on a 7 nm process.
