Classification: CPC H | IPC H

Claim 16:
17. A method for forming a package component, comprising:
providing or receiving a substrate;
forming a first patterned conductive film over the substrate;
selectively depositing a second conductive film over the first patterned conductive film to form a conductive layer comprising the first patterned conductive film and the second conductive film, wherein a resistance of the second conductive film is lower than a resistance of the first patterned conductive film;
forming a through via penetrating through the substrate;
forming a third conductive film in the through via; and
forming a fourth conductive film covering an exposed surface of the third conductive film to form a through via structure comprising the third conductive film and the fourth conductive film, wherein a resistance of the fourth conductive film is lower than a resistance of the third conductive film.
