It's always good to question subsidies like this, but the question you ask ("does income tax on the created jobs pay for the subsidies") is the wrong one: The state is not investing into this for a monetary return from income taxes-- he is paying for strategical reasons/supply chain security, and the "price" is to compensate for the fact that labor costs and regulations make building chip foundries in the US more expensive. So what you would need to ask would be more like: Is the subsidiy higher than it needs to be to lure chipmakers into the US? And that is much harder to answer...
