Would you mind explaining how the production becomes more hazardous?

  I think parent might have confused Germanium with Cadmium? I am no chemist. It could also require other more toxic substances to control reactions or act a carrier. The whole area around Sunnyvale is littered with toxic waste dumps from semiconductor manufacturing. [1] From [2], it says, "Some reactive intermediate compounds of germanium are poisonous", when then references [3] but I can't find the specific citation. I think Germanium is getting lumped in with other toxic chemicals used in semiconductor manufacturing like gallium arsenide, cadmium, etc. [1] https://www.epa.gov/superfund-redevelopment-initiative/superfund-sites-reuse-california https://www.epa.gov/superfund-redevelopment-initiative/super...

    > The whole area around Sunnyvale is littered with toxic waste dumps from semiconductor manufacturing. Makes me wonder how this is dealt with in Taiwan.

      There is a reason those kinds of industries avoid "the west".

    Fairchild in south San Jose too. When I was at ST High School in the mid 90s calling other kids a Fairchild settlement kid was an insult. https://www.kqed.org/news/11630861/how-silicon-valley-industry-polluted-the-sylvan-california-dream https://www.kqed.org/news/11630861/how-silicon-valley-indust...
