Apple has been struggling to produce enough sapphire displays in time for the iPhone 6, but after going straight to the source of the freakishly indestructible glass – GT Advanced Technologies – MIT has learned of the company’s plans to use a giant machine that may solve all of Apple’s sapphire production problems, one slice of sapphire at a time.
The problem with sapphire glass is that while amazingly durable, it’s also ridiculously hard to produce in thin smartphone sized sheets. Apple’s current production methods involve taking a large chunk of sapphire and sawing it down to just a few hundred micrometers thick. It’s time consuming and wasteful, but GT’s new Hyperion 4 Ion Implanter technology could allow it to make paper thin sheets of pure crystal sapphire glass just by bombarding it with hydrogen ions.
