“…Thereby, in the presence of an interconnect full open defect generating a floating line voltage V FN , given a pattern (P) setting the rest of the circuit to a known state, the charge stored in the capacitors connected to neighboring structures (Q N (P,V FN )) plus the charge stored in the parasitic capacitors of the transistors (Q TR (P,V FN )) driven by the floating line must be equal to the constant trapped charged (Q o ) accumulated during the fabrication process, as indicated in eq (1).…”

“…Among open defects, interconnect opens have received significant research effort since they have become more frequent with technology shrinking due to the replacement of aluminum by copper in metal interconnections [1] together with the increasing number of vias/contacts [2]. In the presence of an interconnect full open defect, the affected line is disconnected from its driver, becoming electrically floating.…”

“…NTERCONNECT open defects are becoming more common in CMOS technologies due to the increasing number of contacts and vias [1] and the replacement of aluminum by copper in interconnections [2]. An interconnect open defect consists of the partial or total breaking of the electrical connection between two points of an interconnect line.…”

“…Stamper [9] has assessed the variability of both AVSiO2 and Cu/SiOz interconnects. For a 350 nm linewidth, subtractive aluminum process the total 4-sigma range of variation was 61% with a lithographic linewidth variation of 43%.…”
