That might have been true in the early 2000s when they were growing the Hillsborough Oregon campus but most new fabs are opening in Arizona for taxation and political reasons. I don't have the numbers to back it up, but based on articles about Intel layoffs I believe that Intel has been shedding jobs in Oregon for a while now.
I am saying that all this stuff should have never left the bay area, and the bay area should have millions more people than it does today.
Arizona is also a mistake --- a far worse place for high tech than Oregon!. It is a desert real estate ponzi scheme with no top-tier schools, no history of top-tier high-skill intellectual job markets. In general the sun belt (including LA) is the land of stupid.
The electoral college is always winning out over the best economic geography, and it sucks.
This wiki page has a list of Intel fab starts, you can see them being constructed in Oregon until 2013, and after that all new construction moved elsewhere. https://en.wikipedia.org/wiki/List_of_Intel_manufacturing_si...
I can imagine this slow disinvestment in Oregon would only encourage some architects to quit an found a RISC-V startup.
