Patent ID: 7568278

Claim:
A method for manufacturing an inductor using a system-in-package (SIP), the method comprising: forming a penetration hole in a silicon substrate, depositing a first barrier metal in an inner wall of the first penetration hole, entirely filling the first penetration hole with a first metal material, and planarizing the metal material to form a first penetration electrode; depositing an insulating film on a first surface of the silicon substrate including the first penetration electrode, and patterning the insulating film to form an inductor hole and a second penetration hole aligned with the first penetration hole; depositing a second barrier metal in inner walls of the inductor hole and the second penetration hole, entirely filling the inductor hole and the second penetration hole with a second metal material, and planarizing the second metal material to form an inductor and a second penetration electrode; and depositing a protective film on the insulating film and performing a back grind process such that the first penetration electrode is exposed from a second surface of the silicon substrate, the second surface being opposed to the first surface.
