Apple's Huge 3nm Chip Orders for iPhone 15 Pro and M3 Macs Helping to Maintain TSMC's Fab Utilization Rates

Apple supplier TSMC is making strides to improve its production capacity for chips based on its cutting-edge 3-nanometer process technology, according to industry sources, which is expected to debut in this year's iPhone 15 Pro and upcoming MacBook models.

DigiTimes reports that TSMC's 5nm fabrication capacity began to loosen in November 2022 as a result of reduced orders from Apple, amongst other partners, with orders for iPhone chips alone having been slashed by 30%. However, the Taiwanese manufacturer has apparently been able to keep its utilization rate at 70% or higher thanks to Apple's thirst for 3nm:

TSMC continues to improve its capacity utilization for 3nm process technology, which is expected to approach 50% at the end of March, the sources said. The foundry will also grow the process output to 50,000-55,000 wafers monthly in March, with Apple being the main customer.

Apple's upcoming ‌iPhone 15 Pro‌ models are expected to feature the A17 Bionic processor, Apple's first ‌iPhone‌ chip based on TSMC's first-generation ‌3nm‌ process, also known as N3E.

The first-gen ‌3nm‌ process is said to deliver a 35% power efficiency improvement over TSMC's 5nm-based N4 fabrication process, which was used to make the A16 Bionic chip for the iPhone 14 Pro and Pro Max. The N3 technology will also offer significantly improved performance compared to current chips manufactured on 5nm.

Apple's next-generation 13-inch and 15-inch MacBook Air models are both expected to be equipped with an M3 chip, which is also likely to be manufactured on the ‌3nm‌ process for further performance and power efficiency improvements. Apple is also reportedly planning to release an updated version of the 13-inch MacBook Pro with an M3 chip. The M2 chip and its higher-end Pro and Max variants are built on TSMC's second-generation 5nm process.

Orders for new AI processors from Nvidia and AMD, as well as Apple's new ‌iPhone‌ chip, are expected to help TSMC avoid further fab utilization declines in the second quarter, DigiTimes' sources said.

The industry is moving from nm to Ångströms. The node after 2 nm will be 18 å for example.

What is the actual transistor size? I haven't been following that closely these past few years.
From Wikipedia:

The term "5 nm" has no relation to any actual physical feature (such as gate length, metal pitch or gate pitch) of the transistors being 5 nanometers ('https://en.m.wikipedia.org/wiki/Nanometer') in size. According to the projections contained in the 2021 update of the International Roadmap for Devices and Systems ('https://en.m.wikipedia.org/wiki/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] ('https://en.m.wikipedia.org/wiki/5_nm_process#cite_note-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 ('https://en.m.wikipedia.org/wiki/7_nm_process').

Typically the chip manufacturer refers to its own previous process node (in this case the 5 nm process ('https://en.m.wikipedia.org/wiki/5_nm_process')node) for comparison. For example, TSMC has stated that its 3 nm FinFET chips will reduce power consumption by 25-30% at the same speed, increase speed by 10-15% at the same amount of power and increase transistor density by about 33% compared to its previous 5 nm FinFET chips.[17] ('https://en.m.wikipedia.org/wiki/3_nm_process#cite_note-17')[18] ('https://en.m.wikipedia.org/wiki/3_nm_process#cite_note-18') On the other hand, Samsung has stated that its 3 nm process will reduce power consumption by 45%, improve performance by 23%, and decrease surface area by 16% compared to its previous 5 nm process.

3 nanometer circuits... I still find this amazing. The first processor I ever experimented with was at 3500 nm. Not a typo.

Holy crap! It's marketing BS ?

I thought something was off. Years ago I remember reading that below 5nm might be impossible due to quantum effects / hard physical reality.

Obviously marketing doesn't have those limitations.

it doesn’t seem real because it isn’t. The whole nm thing largely lost meaning and it has little to do with the actual transistor size. Sure there has been huge progress and they can squeeze so many more transistors in the same area than they used to, but 3nm is a misleading number. The truth is that we got to the limit of what’s physically possible: silicon atoms have a size and you can’t change that fact no matter how much research you do.

Does anyone else see what’s happening here? Eventually the nm will require floating point numbers, and these devices will be in more everyday devices running chatGPT 10.0 and replace us (although I think 100-200 year timeline on that last part, if not 5000).
