  • Test structure and method for calibrating three-dimensional thermography fault isolation tool
    Patent number: 9417309
    Abstract: An apparatus for calibrating a three-dimensional thermography fault isolation tool, includes: a substrate having two or more pins; a first semiconductor die coupled to the substrate; a first heat generating test component at the first semiconductor die; and a second heat generating test component, wherein the first heat generating test component and the second heat generating test component are located at different respective heights; wherein the first heat generating test component is configured to produce a first temperature change in response to a voltage applied by the three-dimensional thermography fault isolation tool to the two or more pins; and wherein the second heat generating test component is configured to produce a second temperature change in response to the voltage or another voltage applied by the three-dimensional thermography fault isolation tool.
