Apple has awarded $45 million from its Advanced Manufacturing Fund to Corning Incorporated, a supplier of precision glass for iPhone, Apple Watch, and iPad.

The funding will expand Corning’s manufacturing capacity in the US and drive research and development into new technologies that support durability and long-lasting product life, building on both Apple and Corning’s commitment to protecting the environment.

Corning has already received $450 million from Apple’s $5 billion Advanced Manufacturing Fund over the last four years.

Apple’s investment helps support more than 1,000 jobs across Corning’s US operations in Kentucky and other facilities.

The investment has also helped facilitate research and development into modern glass processes, which led to the creation of Ceramic Shield, a new material that is tougher than any smartphone glass.

“Apple and Corning have a long history of working together to accomplish the impossible,” said Jeff Williams, Apple’s chief operating officer.

“From the very first iPhone glass, to the revolutionary Ceramic Shield on the iPhone 12 lineup, our collaboration has changed the landscape of smartphone cover design and durability.

“Ceramic Shield is a prime example of the technologies that are possible when deep innovation meets the power of American manufacturing. We’re so proud to work alongside Corning, whose 170-year-old legacy is a testament to the ingenuity of the US workforce.”
