Abstract:
The present application relates to a technical field of semiconductors, and discloses a device having a physically unclonable function, a method for manufacturing same, and a chip using same. The may method include: providing a substrate structure that comprises: a substrate comprising encryption device areas and reference device areas; at least one first gate structure on the encryption device areas and used in an encryption device and a first spacer layer on a side wall of the first gate structure; a first interconnection layer on the encryption device areas and the first spacer layer; at least one second gate structure on the reference device areas and used in a reference device and a second spacer layer on a side wall of the second gate structure; and a second interconnection layer on the reference device area and the second spacer layer; performing first ion injection, so as to introduce first impurities into the first interconnection layer; performing second ion injection, so as to introduce second impurities into the first and second interconnection layers, where a password of the device having a physically unclonable function is determined according to a drain current of each encryption device and a drain current of a reference device corresponding to the encryption device.

Claim (Index 17):
The device according to  claim 12 , wherein:\n a top of the first spacer layer is higher than a top of the first gate of the first gate structure; and a top of the second spacer layer is higher than a top of the second gate of the second gate structure.
