    摘要: A semiconductor device includes a conductive component on a substrate, a passivation layer on the substrate and including an opening that exposes at least a portion of the conductive component, and a pad structure in the opening and located on the passivation layer, the pad structure being electrically connected to the conductive component. The pad structure includes a lower conductive layer conformally extending on an inner sidewall of the opening, the lower conductive layer including a conductive barrier layer, a first seed layer, an etch stop layer, and a second seed layer that are sequentially stacked, a first pad layer on the lower conductive layer and at least partially filling the opening, and a second pad layer on the first pad layer and being in contact with a peripheral portion of the lower conductive layer located on the top surface of the passivation layer

    摘要: Provided are a wafer bonding apparatus for accurately detecting a bonding state of wafers in a wafer bonding process and/or in a wafer bonding system including the wafer bonding apparatus. The wafer bonding apparatus includes a first supporting plate including a first surface and vacuum grooves for vacuum-absorption of a first wafer disposed on the first surface, a second supporting plate including a second surface facing the first surface. A second wafer is on the second surface. The wafer bonding apparatus and/or the wafer bonding system include a bonding initiator at a center portion of the first supporting plate, and an area sensor on the first supporting plate and configured to detect a propagation state of bonding between the first wafer and the second wafer.
