3 nm lithography process

The 3 nanometer (3 nm or 30 Å) lithography process is a technology node semiconductor manufacturing process following the 5 nm process node. Commercial integrated circuit manufacturing using 3 nm process is set to begin some time around 2023.

The term "3 nm" is simply a commercial name for a generation of a certain size and its technology, and does not represent any geometry of the transistor.

P1278[edit]

Intel's 5-nanometer (renamed as Intel 20A) process node is expected to ramp around the 2H2024/2025 timeframe.

Samsung[edit]

On May 24 2017 Samsung announced they will be switching to a transistor they call Multi-Bridge-Channel FET (MBCFET), an extension of a Gate-all-around (GAA) FET. This is planned for somewhere after the 5nm node but the exact timeline or specification is currently unknown.

TSMC[edit]

N3 technology will offer up to 70% logic density gain, up to 15% speed improvement at the same power and up to 30% power reduction at the same speed as compared with N5 technology (According to TSMCs website). If this holds true we could see 300+ MT/mm2.
