Your cue to pay your nanny more?
Not all jobs are worth the same amount. Nannying is quite important but it is low skill (meaning supply of labor is high) and thus will probably command lower wages than semiconductor manufacturing.
She describes her sister’s job as filling a cartridge with wafers, and then sending it into some robotic conveyance. And then just sitting there. Probably about as much skill as navigating a car through rush hour traffic to soccer practice.
Her sister isn’t installing HF lines, or clean room downdraft systems. Functional equivalent of flipping burgers.
My understanding is that for a while Intel was trying to only hire PhDs for running its tools, but found that the especially academic individuals had little interest in the statistical process control of wafer manufacturing. In high volume manufacturing, the core engineers are still chemical engineers with bachelors degrees.
