In late April 2022, Patently Apple posted a report titled " A new report claims that an iPhone with a 2nm Processor could be Disappointingly Delayed to between 2025 and 2026." On Sunday, The Financial Times posted a report titled "Semiconductor giants race to make next generation of cutting-edge chips."

The Financial Times reports that "the world’s leading semiconductor companies are racing to make so-called '2 nanometer' processor chips that will power the next generation of smartphones, data centers and artificial intelligence.

TSMC, which dominates the global market in processors, has already shown the process test results for its 'N2' — or 2 nanometer — prototypes to some of its biggest customers, including Apple and Nvidia, according to two people with direct knowledge of the discussions.

TSMC, which has said that mass production of N2 chips will begin in 2025, typically launches the mobile version first, with Apple as its lead customer. Versions for PC and then high-performance computing chips designed for higher power loads will come later.

Apple’s latest flagship smartphones, the iPhone 15 Pro and Pro Max, were the first mass-market consumer devices to deploy TSMC’s new 3 nanometer chip technology when they were introduced in September this year.

The challenges of moving from one generation, or 'node,' of process technology to the next intensify as chips keep getting smaller, raising the possibility of a mis-step that could see TSMC’s crown slip.

TSMC told the Financial Times its N2 technology development was “progressing well and on track for volume production in 2025, and will be the most advanced semiconductor technology in the industry in both density and energy efficiency when it is introduced." 

There's a lot more to The Financial Times report report covering Samsung, Intel and more.

A few months back, The Financial Times posted a video titled "The race for Semiconductor Supremacy as presented below. The 28 minute video is an excellent overview of the semiconductor industry worth watching, especially for current and future engineering students.
