The start-up plan of the improved version "N3E"

A few days ago, IT House reported that due to the low yield of TSMC 3 nm process, iPhone 15 series using A17 and M3 may become a small chip between a chip manufactured by 3 nm process and a chip manufactured by 5 nm process. According to DigiTimes, in order to solve the problem of low quality rate in 3 nm process "N3", TSMC began to launch the improved version "N3E" of "N3".

Mass production begins in the second half of 2023 (July to December)

The media reported that TSMC will start manufacturing semiconductors using the 3 nm process "N3" in the second half of 2022 (July-December) and the improved "N3E" in the second half of 2023 (July-December). The production line is expected to be ready for operation in the second quarter of 2023 (April-June) before TSMC N3E begins mass production. In N3E, the extreme ultraviolet (EUV:Extreme Ultra Violet) mask is expected to reduce the number of exposures than originally scheduled, but even in this case, the transistor density is only 8% lower than N3 and 60% higher than 5 nm process "N5". Elchapuzas reported that the rate of good products during the trial production stage was much higher than that of the 3 nm process "N3B (N3B is not specified)".
