Apple's Arizona Sapphire Plant May See Expansion to Bolster Yields

As construction on Apple and GT Advanced's sapphire manufacturing plant in Mesa, Arizona, progresses, the two companies are already looking at expanding their available space.

According to AppleInsider, several companies in the area are currently bidding on a potential expansion, which would possibly allow GT Advanced to put out even greater quantities of sapphire for use in Apple's products. While it remains unclear just how Apple will use the sapphire, there have been several strong hints and equipment orders pointing towards sapphire displays for the upcoming iPhone 6.

Announced in November, the Mesa, Arizona facility currently under construction will house approximately 700 employees with enough sapphire-making equipment to supply screens for Apple's entire line of iPhones – capacity is at 100 to 200 million sapphire displays per year, according to an analyst estimate. If the proposed expansion is also used for sapphire manufacturing, GT Advanced's output capabilities could increase even further.

Public records from the U.S. International Trade Administration suggest that there are several vacant parcels of land adjacent to the area where Apple is already building.

Although the exact purpose of the second unit is unknown, the build would likely be similar to Cascade's building as project planners are said to be fielding bids from existing construction companies and material suppliers. Firms actively working on the project include Rosendin Electric, Wesco Distribution and Graybar Electric, among others.

While documents filed with the Foreign-Trade Zone Board in January suggested Apple was aiming to open the plant in February, construction is ongoing. The site does appear to be functioning in a partial capacity, however, powered by an array of temporary generators, possibly already producing sapphire for future products.

The circles and tracks there are remnants of the old GM proving grounds.
They have since moved to Yuma away from the home developers who have encroached onto the proving grounds making it harder to test prototype stuff.

I knew a developer bought a chunk of that land to build more houses but if they had anything left over Apple would have great room to expand.

Intel has been doing this over in Chandler the last couple of years and they are really pumping up production on hardware now.

The circles are part of the old, abandoned GM dessert proving grounds.

That giant circle in the center of the image is odd. I didn't realize that sapphire production required a particle accelerator.

The big ring in the left/west of the facility looks a lot like a particle accelerator.

In fact, it looks exactly like a smaller version of Fermilab's Tevatron Collider.

The question is: what do they need a particle accelerator for?

You're joking, of course. As a particle physicist that used to work at FNAL, the answer is they don't need one and wouldn't spend the $1B it takes to build one that size for no reason at all.

Not all circles are particle accelerators and not all particle accelerators are circular!
