Samsung insists on launching the 3nm process by mid-2022

Since then, however, it has been accompanied by rather negative news, which speaks of delays, leakages and yields. If we take it from the point of view of MBCFET / GAA technology, it should originally have been deployed on a 4nm process, ie even earlier. In the end, Samsung decided to merge with 3nm production in 2020. Then the start of production was postponed to the beginning of 2021. At the beginning of July 2021, the company was heard that the start of the first generation of 3nm production (3GAE) production is still going according to plan for 2022.

Samsung ‘s 3nm GAA production has two announced versions: Early (3GAE – E as Early) and advanced (3GAP – P as Performance). Shortly after the official July announcement that 3GAE was planned for 2022, an updated Samsung roadmap appeared, in which the 3GAE process was completely missing and only 3GAP painted for 2023 was present:

A media shootout ensued, with many newsrooms expressing outrage at why Samsung was explaining the postponement when the process was canceled altogether. Samsung objected that it was only a deletion from the roadmap, not a cancellation of the process. It was consensually understood that Samsung is continuing to prepare the process, but in view of the significant delay, it will already use it itself, offering it to some very close partners as much as possible. However, the external interested party will not be able to order production on this process.

Somehow it will probably be, because now Samsung has announced that in the first half of 2022 it will start production on a 3nm process (unspecified, but the context shows that it is a delayed 3GAE) for unnamed partners (the plural was actually used). Samsung expects the second generation of the 3nm process (ie 3GAP) in 2023 and plans 2nm production (also GAA / MBCFET) for 2025 (it is now in the early development phase).
