Abstract
A manufacturing method of a package substrate is provided. A conductive substrate is provided. A first photoresist layer is patterned to form first openings. A first conductive layer is formed in the first openings. A second photoresist layer is patterned to form second openings. A second conductive layer contacting the first conductive layer is formed in the second openings. The first and second photoresist layers are removed. A dielectric layer covers the first, second conductive layers and a portion of the conductive substrate. A portion of the dielectric layer is removed. A third photoresist layer is patterned to form a third opening. A portion of the conductive substrate is removed to form a fourth opening. The third photoresist layer is removed. A fourth photoresist layer is patterned to form a fifth opening. A bonding pad is formed in the fifth opening. The fourth photoresist layer is removed.
