Figure 3
Lattice spacing d dependencies on evaluated from two-dimensional data collected during the scanning experiment at the TSV edge, measurement position A, when the X-ray beam hit the via at the W film scallop hill (a) and valley (b) (cf. Fig. 1b). The different slopes of the dependencies indicate varying magnitudes of residual stresses along the y direction. Filled and empty points represent lattice spacing data evaluated for δ azimuthal position intervals of 0–90 and 90–180°, respectively. |
