What's more, the new facility will be powered completely by renewable energy and will create 2,000 jobs.
The factory in Mesa is reported to be in partnership with mineral crystal firm GT Advanced Technologies and will make sapphire components for Apple devices.
These include things like the new Touch ID fingerprint sensor and the new iPhone's camera lense.
In a statement they said:
We are proud to expand our domestic manufacturing initiative with a new facility in Arizona, creating more than 2,000 jobs in engineering, manufacturing and construction. This new plant will make components for Apple products and it will run on 100% renewable energy from day one, as a result of the work we are doing with SRP to create green energy sources to power the facility.
