An integrated circuit chip includes an analog and/or RF circuit block, a digital circuit, and a seal ring structure surrounding and protecting the analog and/or RF circuit block. The seal ring structure comprises a continuous outer seal ring, and a discontinuous inner seal ring divided into at least a first portion and a second portion. The second portion is situated in front of the analog and/or RF circuit block for shielding a noise from interfering the analog and/or RF circuit block.
