摘要
The local strain and texture in Al interconnect wires have been investigated using white and monochromatic re-ray microbeams on the MHATTCAT undulator beam line at the Advanced Photon Source. Intergrain and intragrain orientations were obtained with similar to 0.01 degrees sensitivity using white bears measurements on wide Al pads (similar to 100 mu m) and thin (2 mu m) Al wires. Orientation changes of up to 1 degrees were found within individual grains of the (111) textured Al interconnects. Deviatoric strain measurements indicate small intragranular strain variations, but intergranular strain variations were found to be quite large.
