Abstract:
A semiconductor package includes a first semiconductor chip, a second semiconductor chip and a sealing member. The first semiconductor chip includes a substrate having a first surface and a second surface opposite to the first surface and having an opening that extends in a predetermined depth from the second surface, and a plurality of through electrodes extending in a thickness direction from the first surface, end portions of the through electrodes being exposed through a bottom surface of the opening. The second semiconductor chip is received in the opening and mounted on the bottom surface of the opening. The sealing member covers the second semiconductor chip in the opening.
Abstract:
Provided are an initiator and a method for debonding a wafer supporting system. The initiator for debonding a wafer supporting system includes a rotation chuck having an upper surface on which a wafer supporting system (WSS), which includes a carrier wafer, a device wafer, and a glue layer for bonding the carrier wafer and the device wafer to each other, is seated to rotate the wafer supporting system, a detecting module detecting a height and a thickness of the glue layer and a laser module generating a fracture portion on the glue layer through irradiating a side surface of the glue layer with a laser on the basis of the height and the thickness of the glue layer.
Abstract:
In a semiconductor device, an organic insulation pattern is disposed between first and second rerouting patterns. The organic insulation pattern may absorb the physical stress that occurs when the first and second rerouting patterns expand under heat. Since the organic insulation pattern is disposed between the first and second rerouting patterns, insulating properties can be increased relative to a semiconductor device in which a semiconductor pattern is disposed between rerouting patterns. Also, since a seed layer pattern is disposed between the first and second rerouting patterns and the organic insulation pattern and between the substrate and the organic insulation pattern, the adhesive strength of the first and second rerouting patterns is enhanced. This also reduces any issues with delamination. Also, the seed layer pattern prevents the metal that forms the rerouting pattern from being diffused to the organic insulation pattern. Therefore, a semiconductor device with enhanced reliability may be implemented.
