The interconnection element 13 tapers from the surface 1321 to the surface 131u (e.g., the width of the interconnection element 13 becomes smaller (e.g., gradually smaller) from the surface 1321 to the surface 131u). The width W1 of the portion 131 (e.g., the maximum width of the portion 131) is smaller than the width W2 of the portion 132 (e.g., the minimum width of the portion 132).

[0114] Figure 7 A cross-sectional view of a comparative substrate 5 is illustrated. The substrate 5 includes a dielectric layer 10, a patterned conductive layer 61, an interconnection element 63, and a conductive layer 65.

[0115] The dielectric layer 10 has a surface 10a and a surface 10b opposite to the surface 10a. The patterned conductive layer 61 includes a conductive pad 611 and a conductive trace 612 adjacent to the conductive pad 611. The patterned conductive layer 65 includes a conductive pad 651 and a conductive trace 652 adjacent to the conductive pad 651. The interconnection element 63 is disposed between the patterned conductive layer 61 and the patterned conductive layer 65.

[0116] The conductive pad 611 of the patterned conductive layer 61 is large so that it can be aligned with the interconnection element 63 during the manufacture of the substrate 5. However, such a conductive pad 611 can reduce the available space on the surface 10a of the dielectric layer 10. In addition, since the interconnection element 63 contacts the conductive pad 611 two-dimensionally, cracks can be easily formed at the position / interface 67 between the conductive pad 611 and the interconnection element 63.

[0117] Fig. 8A is a cross-sectional view of a comparative substrate 6. The substrate 6 comprises a dielectric layer 10, a patterned conductive layer 61', an interconnection element 63' and a conductive layer 65.

In this comparative example, the conductive pad 611' is surrounded by the interconnection element 63'. However, since the interconnection element 63' at the surface 10a of the dielectric layer 10 is exposed, the available space on the surface 10a of the dielectric layer 10 (e.g., the space for routing the trace 612') may be smaller.

[0120] Figure 8B is a top view of a comparative substrate 6 according to some embodiments of the present disclosure. Because higher stress may be concentrated at the location 61c, the location 61c where the conductive pad 611' protrudes from the dielectric layer 10 into the interconnection element 63' may have cracked.

[0121] Furthermore, the interconnection element 63' may be irregularly shaped by the laser drilling operation. The irregular shape of the interconnection element 63' may cause the substrate 6 to be electrically disconnected from the semiconductor device disposed on the substrate 6.
