Apple is actively taking steps to stop using Samsung’s technology in its devices, a senior Samsung official told The Korea Times. Industry sources claim that Apple used Samsung only to manufacture the A6 microprocessor found in its iPhone 5 — the design and development were done by Apple alone.

Apple’s recent deal with Taiwan Semiconductor Manufacturing for the future production of quad-core processors could completely sever the connection between Apple and Samsung, which is already strained due to patent battles between the two companies.
A report claims TSMC will produce Apple’s A7 processors free of Samsung technologies, starting in 2014..
