According to unofficial TSMC sources, after having mastered the 5nm technologies, the ones that Apple is expected to use for the Apple A14 processors destined for the iPhones and iPads of this autumn, ready to go even further, with the production technology at 2 nanometers, probably the last node to use current machinery and materials.
Still according to the advances that come from Taiwan, there seems to be still a lot to do and that we must wait before seeing the use and entry into service of the 2 nanometer construction processes (signed nm) for the processors. TSMC would have carried out preliminary research in any case in 2019 and this year will start working on new steps.
As if that wasn't enough, the foundry intends to go even further, knowing full well that the difficulties will be even greater, as it goes on. According to DigiTimes, with the turning point that should come from materials such as germanium, mixed silicon-germanium junctions, the integration of extreme ultraviolet lithography (EUV) at multiple levels.
Developing technology first at 7 nm and then at 5 nm was one of the great challenges of the semiconductor industry. Among the benefits from the reduction in size: higher performance, lower energy requirements and lower costs (due to scale factors). Efforts to produce chips with 2 nanometer technology should translate into improvements in the power / performance ratio for future generations of chips that will be used, among other things, also in the mobile sector.
Recall that, for several years now, all the processors that Apple designs and uses on iPad, iPhone and beyond are built in the TSMC plants. For the iPhones of the last two generations, from the iPhone XR and XS of 2018 then up to the iPhone 11 Pro of this year, the Apple processors are built by TSMC with a 7 nanometer process, further improved for the Apple A13 Bionic processors of the iPhone 11 .
For months, the Taiwanese manufacturer has completed tests and first production tests for the new 5-nanometer process: rumors have it that Apple has already booked a large part of the production capacity of the new plants to build Apple A14 in large volumes for the upcoming iPhone 12 this fall. All macitynet articles that talk about TSMC are available from this page.
For everything you need to know about the current iPhone 11 and 11 Pro, we refer to this in-depth analysis of macitynet. For new models coming this year, however, it is possible to consult this article for iPhone SE 2020, instead all that has emerged so far on the iPhone 12 5G summarized in this article.
