Apple develops its chips using ARM-based designs, which are produced by TSMC (for instance, the Apple A14 chip). The manufacturing process itself is handled by TSMC.
The questions about 5nm and 7nm designs need clarification. Apple doesn’t directly design these chips, but TSMC manufactures them. AMD also uses 7nm technology, though not exclusively theirs.
No, the "5nm" and "7nm" processes are not owned by TSMC. They are developed by other companies.
The "5nm" or "7nm" refers only to the marketing size. That figure doesn't hold any real significance—it mainly indicates whether it's a V6 or V8 engine, but a Toyota/Lexus V8 is distinct from a Ford V8. TSMC's 7nm, GlobalFoundries' 7nm, and Samsung's 7nm all vary in their specifications.
