Мале мале... че то ейпълите били по 5 nm.
https://en.m.wikipedia.org/wiki/Apple_A14и ако преди години са послъгвали по малко, то сега въобще не се срамуват да кажат че тези 5nm нямат нищо общо с размерите.
https://en.m.wikipedia.org/wiki/5_nm_processThe term "5 nanometer" has no relation to any actual physical feature (such as gate length, metal pitch or gate pitch) of the transistors. According to the projections contained in the 2021 update of the International Roadmap for Devices and Systems published by IEEE Standards Association Industry Connection, a 5 nm node is expected to have a contacted gate pitch of 51 nanometers and a tightest metal pitch of 30 nanometers.[3] However, in real world commercial practice, "5 nm" is used primarily as a marketing term by individual microchip manufacturers to refer to a new, improved generation of silicon semiconductor chips in terms of increased transistor density (i.e. a higher degree of miniaturization), increased speed and reduced power consumption compared to the previous 7 nm process.[4][5]
фундаменталните ограничения от тунелния ефект също са ги ударили.
Quantum tunnelling effects through the gate oxide layer on 7 nm and 5 nm transistors became increasingly difficult to manage using existing semiconductor processes.[6]
за дифракцията/маските е пак същата работа.. пък каквато ще да е фирмата, холандска, американска, тайвандска, занзибарска...
