Abstract:
A method includes encapsulating a device die in an encapsulating material, forming a first dielectric layer over the device die and the encapsulating material, forming first redistribution lines extending into the first dielectric layer to electrically couple to the device die, forming an alignment mark over the first dielectric layer, wherein the alignment mark includes a plurality of elongated strips, forming a second dielectric layer over the first redistribution lines and the alignment mark, and forming second redistribution lines extending into the second dielectric layer to electrically couple to the first redistribution lines. The second redistribution lines are formed using the alignment mark for alignment.

Claim (Index 9):
A method of forming a semiconductor device comprising:\n forming a through-via over a carrier; encapsulating a device die and the through-via in an encapsulating material; forming a first dielectric layer over and contacting the device die, the through-via, and the encapsulating material; forming first via openings in the first dielectric layer to reveal the through-via and conductive features of the device die; plating first redistribution lines and an alignment mark, wherein the first redistribution lines comprise first via portions extending into the first via openings, and the alignment mark comprises a first plurality of elongated strips parallel to each other; forming a second dielectric layer over the first dielectric layer, with the alignment mark and first trace portions of the first redistribution lines embedded in the second dielectric layer; forming second via openings in the second dielectric layer to reveal the first redistribution lines, wherein the second via openings are formed using the alignment mark for alignment; and plating second redistribution lines comprising second via portions extending into the second via openings, and second trace portions over the second dielectric layer.
