Abstract: An electrostatic discharge (ESD)-triggered protection apparatus includes a first circuit and a second circuit. The first circuit includes an ESD trigger circuit to sense an ESD pulse and to generate a switching pulse responsive to the ESD pulse; a first ESD discharge device communicatively coupled to the ESD trigger circuit and responsive to the switching pulse to transfer a current generated by the ESD pulse to the ground rail; a control circuit that generates a control signal in response to the switching pulse. The second circuit includes at least one trigger cell buffer that is configured to receive the control signal and to control a second ESD discharge device such that the current generated by the ESD pulse is transferred to the ground rail.

Abstract: A device comprising a semiconductor substrate. The device also comprising a digital block defined on the substrate and having multiple electronic elements. The device also comprises first and second poly layers coupling to the multiple electronic elements, the first and second poly layers extending in parallel through the digital block in a first direction. The device further comprising a third poly layer coupled to the first poly layer and extending through a gap in the second poly layer in a second direction orthogonal to the first direction poly.
