Thanks. This means that domestic ion implanters are even more important than I thought. They used to be monopolized by US.
Yeah I agree and they are also very important in other areas like wide band-gap semiconductors like Silicon Carbide, Gallium Nitride (necessary for power applications like EV and 5G) and for the photovoltaic industry (There is were Kingstone and CETC started in ion implantation before jumping to IC fabrication).
Apart from lithography this is one the technologies that a country may need to develop if they don't want to be subject to other countries irrational will in this area.​

I have some questions that are tangentially related to semiconductors:

it is said that high-end radio frequency (RF) components are monopolised by the usa; "U.S. companies Skyworks, Qorvo, and Broadcom “monopolize” the high-end market for the “key” RF component, the power amplifier chip (or RF chip). There are “essentially” no Chinese firms at all in the high-end RF chip market. U.S. manufacturers such as Qorvo “entirely” dominate the market for another class of RF components: high-end wave filters used in mobile phones.
if china improves its semiconductor industry, is this one of the sectors where over reliance on the usa could be lessened?

2) I think I read somewhere here on the forum that american aesa radars have qorvo chips in them. and I've learnt that chinese military aesa radars are very good quality. If point 1 is true, how did china manage to achieve such quality for aesa radars if they rely on american chips that are probably sanctioned by now? do chinese companies use home-grown" chips that are from bigger nodes but that the chinese semiconductor industry has already mastered?

Developing of SSMB technology will probably work in China and nowhere else....but once it will be industrialized and a commercial product is made out of it, I'd think this will be interesting and useful for everybody in the long term. Apparently SSMB allows easier scaling to shorter light wavelength beyond 13,5nm than current LPP solutions, so it seems a future-proof technology.
I did mention this in one of my posts but it’s not necessarily going to be the case that you can continue toward ever shorter wavelengths for process node shrinks. EUV already has issues with its photons being too high energy and thus causing all sorts of secondary issues with line accuracy from effects like shot noise and material ionization. Going to even shorter wavelengths just exacerbates those kinds of issues, and it may not be workable for ever smaller nodes since these effects ultimately impact effective resolution, especially given that there probably isn’t much room to shrink left.

Uh the vast majority of RF power amplifiers are 2.5-5V low power (mW) devices for use in Bluetooth, Wifi, etc.

These are not used for radar. The volume of lower power RF amplifiers is extremely high (billions) compared to radar high power amplifiers (maybe 1 million at most). They have very different requirements. So there's no contradiction.

No RF chips, American or Chinese, use advanced nodes. Semiconductors for power electronics don’t follow the same performance parameter drivers that semiconductors for computing do.

1- After the Huawei sanctions some Chinese companies are jumping in the bandwagon of RF ICs, even Hisilicon is jumping, in any case if the sanctions get worse this companies will try to fill the hole in domestic demand. So there is a lot of opportunity for growth.

2- Military chips and civilian chips have different specifications, probably the qorvo chips used by U.S. radar are probably designed and fabbed to certain extend differently than civilians chips, in the case of China CETC is the one making this kind of military chips. The problem is that military chips are made without regard of price considerations because the military is willing to pay premium for their high end reliable chips, so any civilian application would probably require some big redesign to reduce costs.​

There are even companies developing the materials and the equipment needed to make the materials for this kind of chips.

From our esteem member @Oldschool, seems like a Chinese EUVL is on the Horizon with SSMB, no question about it, collaborating the post of another esteem members @tokenanalyst , when? with research being done on optics and materials using SSRF, I'll say sooner with 2026/2027 as a conservative date.
