Device yield or die yield is the number of working chips or dies on a wafer, given in percentage since the number of chips on a wafer (Die per wafer, DPW) can vary depending on the chips' size and the wafer's diameter. Yield degradation is a reduction in yield, which historically was mainly caused by dust particles, however since the 1990s ...
[1] [2] On 29 December 2022, Taiwanese chip manufacturer TSMC announced that volume production using its 3 nm semiconductor node (N3) was underway with good yields. [3] An enhanced 3 nm chip process called "N3E" may have started production in 2023. [4] American manufacturer Intel planned to start 3 nm production in 2023. [5] [6] [7]
Typically, integrated circuits are produced in large batches on a single wafer of electronic-grade silicon (EGS) or other semiconductor (such as GaAs) through processes such as photolithography. The wafer is cut into many pieces, each containing one copy of the circuit. Each of these pieces is called a die. 1-watt red power LED die

In semiconductor manufacturing, the 2 nm process is the next MOSFET (metal–oxide–semiconductor field-effect transistor) die shrink after the 3 nm process node.. The term "2 nanometer", or alternatively "20 angstrom" (a term used by Intel), has no relation to any actual physical feature (such as gate length, metal pitch or gate pitch) of the transistors.
The 2021 IRDS Lithography standard is a retrospective document, as the first volume production of a "7 nm" branded process was in 2016 with Taiwan Semiconductor Manufacturing Company's production of 256Mbit SRAM memory chips using a "7nm" process called N7. [2] Samsung started mass production of their "7nm" process (7LPP) devices in 2018. [3]
In semiconductor manufacturing, the International Roadmap for Devices and Systems defines the "5 nm" process as the MOSFET technology node following the "7 nm" node. In 2020, Samsung and TSMC entered volume production of "5 nm" chips, manufactured for companies including Apple, Huawei, Mediatek, Qualcomm and Marvell.
