Samsung is looking at four sites in the U.S. for a new $17 billion chip plant.

Documents filed with Texas state officials showed two locations in Arizona, one in New York, and another in Austin, Texas are being looked at.

The tech giant's new plant would produce devices for Samsung's chip contract manufacturing business, with 1,800 new jobs promised.

The documents also showed how Samsung wants tax benefits from the potential sites.

It's aiming for a combined tax reduction of almost $1.5 billion over 20 years from Travis County in Texas and the city of Austin.

That is up from the near $806 million previously reported.

The documents said both Arizona and New York were offering property tax abatement with - quote - 'significant grants' to fund infrastructure improvement.

Speaking to Reuters Wednesday (March 3), Samsung said it was considering a number of possibilities in terms of expansion.
