Example Embodiment
[0028] Example 1, such as figure 2 As shown, the interconnect failure detection method of Embodiment 1 of the present invention includes the following steps:
[0029] In step s1, at least two interconnection line units with the same interconnection line scale are connected in series to form a failure detection circuit. Because the aforementioned electromigration phenomenon can only be found in interconnects up to a certain length, the size of the selected interconnection unit is actually based on the research needs of the electromigration phenomenon of interconnects of a specific length. . In order to facilitate the description, embodiment 1 of the present invention still adopts such as figure 1 Copper interconnect line unit shown. For example, suppose figure 1 The resistance value of each copper interconnection line with a length of 400 microns shown is 500Ωm, then as figure 1 The minimum interconnection line unit composed of 5 copper interconnections in parallel is equivalen...
Example Embodiment
[0036] Example 2, such as image 3 As shown, the interconnect failure detection method of Embodiment 2 of the present invention includes the following steps:
[0037] In step s10, at least two interconnection line units with the same interconnection line scale are connected in series to form a failure detection circuit. Because the aforementioned electromigration phenomenon can only be found in interconnects up to a certain length, the size of the selected interconnection unit is actually based on the research needs of the electromigration phenomenon of interconnects of a specific length. . In order to facilitate the description, the second embodiment of the present invention still adopts such as figure 1 Copper interconnect line unit shown. For example, suppose figure 1 The resistance value of each copper interconnection line with a length of 400 microns shown is 500Ωm, then as figure 1 The minimum interconnection line unit composed of 5 copper interconnections in parallel is ...
