Patent ID: 6867610

Claim:
A test structure for testing of connected substrates, said test structure comprising: a first substrate comprising: at least one electrically conductive first probe pad providing electrical contact to an external device; a plurality of electrically conductive first bond pads; and at least one electrically conductive first probe line that provides electrical contact between said at least one first probe pad and at least one of the plurality of first bond pads; a second substrate comprising: a plurality of electrically conductive second bond pads; an electrical connection providing electrical contact between at least two of said second bond pads; and a plurality of electrically conductive bumps being formed on and electrically connected to said second bond pads; said second substrate being attached to said first substrate, the plurality of first bond pads and the plurality of second bond pads facing each other, said bumps providing electrical contact between said first and second bond pads.
