Abstract:
1. A method of manufacturing a device, the method comprising: forming a semiconductor device on a first surface of a semiconductor substrate; forming a through-via electrode to be electrically connected to the semiconductor device and extend toward a backside surface of the semiconductor substrate, which is opposite to the first surface of the semiconductor substrate; removing a portion of the semiconductor substrate from the backside surface to form a second surface opposite to the first surface such that a portion of the through-via electrode protrudes above the second surface; forming a silicon nitride layer and a first silicon oxide layer having a greater thickness than the silicon nitride layer on the second surface; exposing the through-via electrode from the first silicon oxide layer and the silicon nitride layer; and forming a through-via electrode pad to be electrically connected to the exposed through-via electrode.
