Thanks to all contributors with their comments/ideas. The main point of my original story "shared pain shared gain" was:
1) the transition in HVM to EUV litho around 2018-2019 for leading edge logic chip manufacturing has resulted in major changes and appears to still have quite important consequences.
2) the capital intensity and EUV-tooling experience / R&D that is needed to economically employ this EUV-technology has resulted in almost unsurmountable market barriers for new users of EUV-litho in logic chip manufacturing.
3) there are 3 leading edge logic manufacturers that now use EUV: TSMC, Samsung and Intel. Two are (original) IDMs (Samsung and Intel), one is Foundry only (TSMC).
4) it appears that EUV-litho is only long-term economically feasible when used in large scale and flexible Foundry operation/applications. The 2 IDMs have realized that and have been developing Foundry operation of EUV logic chip manufacturing.
5) the question now is: what is needed and optimal in the future for the leading edge logic chip manufacturing community in the western world: a monopoly (TSMC), a duopoly (TSMC + Samsung) or a triopoly (TSMC + Samsung + Intel-IFS).
6) a monopoly sounds scary, but looking at the history of the litho-market shake-out (ASML versus Nikon and Canon) has learned that the open-innovation systems-approach of ASML was the winning strategy. And the semi world continues to function more or less just fine after getting used to the
trusted litho-monopoly of ASML. The base of ASML is in NL and its many other locations for subsystem manufacturing in Germany, USA guarantees a trusted supply line operated by this monopolist ASML. And with the US calling the shots regarding allowed customers of ASML's EUV tooling (no China).
7)Taiwan (23 Million people) is a relatively small country, similar like NL (18 Million people), so it has (quite) limited internal resources of people and finances. Taiwan and NL have quite a similar GDP of around 1 Trillion US$.
8) it appears to me that TSMC is using the same open-innovation systems approach in large-scale (now EUV-based) leading edge logic chip manufacturing. Since 2008 TSMC has developed this open-innovation approach: see
https://www.tsmc.com/english/dedicatedFoundry/oip
At the same time TSMC has developed some hugely beneficial internal proprietary EUV tooling expertise (see eg
https://pcge.eu/2024/05/tsmcs-euv-triumph-amplifying-tools-boosting-wafers-and-unmatched-pellicles/)
9) TSMC is rapidly diversifying it's geographical manufacturing base expanding to USA, EU and Japan. I think this approach is key in keeping the support of the western world related to supply chain and geopolitical worries around chips.
10) TSMC appears to aim for ~30% (relative to total revenue)) annual capital investments to keep up with demand. This rapid growth with healthy gross margin of around 50-60% appears to be economically sustainable, especially now that for the first time other governments like USA, Japan, EU are supporting TSMC financially with these huge capital investments.
11) the late entry of Intel-FS into the present duopoly market of TSMC and Samsung (IFS is estimated to receive some meaningful revenue only around 2027 (
https://www.reuters.com/technology/...-meaningful-revenue-2027-cfo-says-2024-09-04/) makes one wonder how IFS will keep up with the relentless expansion/investments of TSMC during the coming 10 years.
12) if IFS is strategically/financially controlled by Intel and if the fabless Intel Product segment is really free to choose its optimum leading edge logic manufacturing foundry (as it now seems to do), what is the need to keep these 2 Intel units in a single company in the long-term? Looking at the success of the fabless leading edge chip developers (Apple, NVIDIA etc) there seems to be no need for tight single-house IDM's.
13) if TSMC can serve the leading-edge logic chip manufacturing well in the coming 5-10 years, why would private investors invest in IFS. There are many interesting investing options available for private investors?
14) I do not worry about regulatory issues for TSMC's effective monopoly in a EUV-based logic chip manufacturing market. The major western countries in this ecosystem (USA, EU, Japan) have already decided to invest tax-payers (!) money in TSMC.
15) trust takes a long time to develop and it seems TSMC is now the Trusted Foundry for the western leading edge logic manufacturing.
Will IFS get the time and funding that is needed to develop a similar trust to have a meaningful role to become a happy player for all its stakeholders as a (relatively) small player in a triopoly market governed/ruled by geopolitical supply considerations?
Or will the "shared pain shared gain" model that resulted in the current litho market (ASML, versus very small players Nikon and Canon) be also the final winning model in EUV-based leading edge logic chip manufacturing (TSMC, versus small players Samsung and IFS)?
Any further thoughts/comments are very much appreciated.
