TSMC yields too low iPhone14 abandoned 3nm process to 4nm

Core Research Institute news, with Samsung's step by step, TSMC is also making an impact to higher process, in order to obtain huge orders from the world's top technology companies, including Apple.

According to the plan, next year's release of the iPhone 14 built-in A16 bionic chip, will use TSMC's latest 3nm process, but still using FinFet architecture process.

But in recent days, industry sources revealed that TSMC 3nm process trial yield is not too satisfactory, will delay the launch of this process.

This means that the mass production of A16 bionic technology, which is expected to be used for the iPhone 14 series in 2022, has been delayed and Apple will have to use the previous generation's nodes instead.

Apple has reportedly received orders for 4nm chips from TSMC, with production expected to begin in Q4 2021. The iPhone maker is also said to have booked an initial 3nm order from the Taiwanese manufacturer, meaning it will have a head start on the competition. TSMC will reportedly mass produce 3 million chips in the second half of next year, which could be used in the iPhone 14 series.

Given that the iPhone is Apple's biggest moneymaker, that product line will be given priority. Like TSMC, Samsung is facing production issues in its 3nm GAA process, so one would think TSMC would have a considerable lead against Samsung. However, as you can see, things are never that simple. The A16 Bionic and Qualcomm's Snapdragon 898 Plus could be built on its same 4nm technology if TSMC can't find a way to improve yields and increase production.
