Semiconductor structures having backside metal die damage rings and methods for manufacturing and testing thereof

A method, comprising:

• providing a semiconductor substrate having an integrated circuit formed therein;
• forming semiconductor devices in the semiconductor substrate;
• forming a first interconnect structure on a first side of the semiconductor substrate overlying and electrically coupled to the semiconductor devices;
• forming a second interconnect structure on a second side of the semiconductor substrate underlying and electrically coupled to the semiconductor devices, wherein the first interconnect structure, the semiconductor devices, and the second interconnect structure define a backside metal die damage ring (BMDDR) partially or entirely surrounding the integrated circuit;
• forming an input element on the semiconductor substrate that is electrically coupled to the BMDDR at a first position;
• and
• forming an output element on the semiconductor substrate that is electrically coupled to the BMDDR at a second position, wherein the BMDDR forms a continuous electrical circuit between the input element and the output element.
