Abstract:
1. A structure comprising: a plurality of dielectric layers having aligned process control monitor (PCM) pads in at least one scribe line, a topmost one of the PCM pads being located in a topmost metal line layer and having a metalized region and a non- metalized region; and a conductive structure patterned in a contact layer above the topmost one of the PCM pads, the conductive structure electrically directly contacting the topmost PCM pad and connecting the topmost PCM pad to a device under test above a level of the topmost PCM pad, wherein the conductive structure overlies a portion of the metalized region so as to leave a portion of the topmost PCM pad uncovered to permit direct contact by a probe, but does not overlie the non-metalized region.
