Abstract:
A die including a corrosion monitoring feature, comprising:a surface including an active die region and a scribeline region that is adjacent said active die region;an insulating layer disposed above said surface and includes a first corrosion sensitive metal plug and a second corrosion sensitive metal plug in said scribeline region; anda metallization layer positioned above said insulating layer, wherein said first corrosion sensitive metal plug and said second corrosion sensitive metal plug in said scribeline region and said metallization layer disposed above said second corrosion sensitive metal plug are patterned to provide said metallization layer with a first opening extending for a top surface of said metallization layer down to a top surface of said second corrosion sensitive metal plug such that a solvent introduced above said top surface of said metallization layer flows into said second corrosion sensitive metal plug disposed below through said first opening in said metallization layer.
