A feud is heating up between Arizona workers and the world’s leading chipmaker after the company claimed the US doesn’t have the skills to build its new factory::TSMC wants to bring in foreign reinforcements to get its Arizona factory running because it claims there aren’t enough qualified local workers.
Gamers Nexus recently did a really good video about paying contractors to build out their acoustic testing chamber. In theory, that is just “put foam on the walls” but they go into everything ranging from which spikes are foam versus metal, how cabling and ventilation are run, and even what is under the floor.
And that is where the expertise comes into play. Theoretically, any competent contractor can follow instructions and build a fab. If you ever meet a competent contractor, protect them with your life.
The reality is that TSMC is going to be constantly having to fly out their people to inspect construction work, indicate what needs to be redone, etc. At which point… why are they paying others to do stuff they need to redo anyway?
Modern fabs are some of the most complex things on the planet. They need to be if they are operating at the nanometer scale (let alone sub 10 nm scale… even accounting for the shenanigans that are used to define those scales for marketing purposes).)
I don’t understand your example. You don’t just tell someone “Hey, I want an acoustic testing chamber.”
Your “experts” are going to have the plans already made and the contractors build to that spec. The contractors don’t ‘decide where to use metal or foam. Your experts’ building plans should have that already in there, otherwise they aren’t much of an expert.
Have you ever worked with contractors?
Nothing is ever done truly to spec. And you also learn fun lessons about the ramifications of not specifying exactly what size and head screws to use on that cabinet. Every other cabinet said to use zinc plated square maxi-loc head 1.5 inch screws, but this cabinet didn’t specify so they actually used iron phillips head screws because they had extras. Or maybe that is actually a gang box and now you have the problem where there is not enough clearance to have a light switch on each side of a wall.
Now extrapolate that to something where minute differences can completely break processes months or years down the line.
The GN acoustic chamber is a good example of just what kind of thought goes into something like that. And that is caveman shit relative to a fab.
And just to be clear, this is not me shitting on contractors. A halfway decent contractor is way better at building stuff than I ever will be and it is important to actually specify anything you care about.
But also, as someone who needs to redo his floors because the folk the previous owners hired were grossly incompetent? Fuck them contractors.
