Abstract
A metal interconnect structure formed over a substrate in an integrated circuit that traverses a scribe-line boundary between a first die and a second die includes at least one metal interconnect line that traverses the scribe-line boundary. A switch is coupled between the at least one metal interconnect line and the substrate, the switch having a control element coupled to a scribe-cut control line. The control line turns the switch on if the two dice are separated into individual dice and turns the switch off if the two dice are to remain physically connected so that the interconnect line may be used to make connections between circuits on the two dice.
Claims1
A method for protecting from contamination a die having a metal line that crosses a scribe boundary comprising:
- separating the die from adjacent die to expose the metal line;
- and
- connecting the metal line to the substrate potential in the die.
