Interesting stuff. Yeah the semiconductor equipment is hard for newcomers, luckily for the Chinese their solar industry, their packaging industry and their military electronic industry was big enough that served as a training ground for many equipment companies so the transition to semiconductor ICs was less hard than otherwise.I mean, an ion implanter is literally a particle accelerator. already pretty amazing. but to get information about buried structure as part of process metrology? this is part of why semiconductor equipment is so hard for new countries to catch up in yet tiny Netherlands has ASML (which was spun off from Philips). it has its roots in vacuum tube and radio stuff from 100+ years ago or were paid for by insane military spending in the Cold War era when Asian countries were still crushed under imperialist boots.
There is another group of companies that will become more relevant in the coming years but this group come from the semiconductor equipment repair industry, a lot of experience gained from decades of repairing semiconductor equipment and I have been reading some encouraging stories.
