Claim Text:
1. A method for fabricating an electronic device package, comprising: providing a electronic device chip, wherein the electronic device chip comprises: a semiconductor substrate having a front side and a back side, wherein the semiconductor substrate has a first thickness; an electronic component disposed on the front side of the semiconductor substrate; and an interconnect structure disposed on the electronic component, wherein the interconnect structure is electrically connected to the electronic component; performing a thinning process to remove a portion of the semiconductor substrate from the back side thereof, thereby forming a thinned semiconductor substrate having a second thickness less than the first thickness; removing a portion of the thinned semiconductor substrate and a portion of a dielectric layer of the interconnect structure from a back side of the thinned semiconductor substrate until a first metal layer pattern of the interconnect structure is exposed, thereby forming a through hole; and forming a TSV structure in the through hole; and mounting the electronic device chip on a base, wherein the back side of the thinned semiconductor substrate is closer to the base than a front side of the thinned semiconductor substrate.
