Micron to build $20 billion chip factory in upstate New York

Tech giant Micron said it will invest $20 billion in a new chip factory in Upstate New York, and up to $100 billion over twenty years if it decides to expand — another sign of a domestic semiconductor manufacturing boom.

Micron said it will build the factory in Clay, N.Y., just north of Syracuse, with the first phase to run through the end of the decade. The site could eventually include four factories if Micron opts to continue building.
