摘要:
A wafer level chip scale package may have a gap provided between a solder bump and a bump land. The gap may be filled with a gas. A method of manufacturing a wafer level chip scale package may involve forming a redistribution line having a first opening, forming a seed metal layer having a second opening including an undercut portion, and forming the gap using the first and the second openings.

Packaged integrated circuit devices include a package substrate and a multi-chip stack of integrated circuit devices on the package substrate. The multi-chip stack includes at least one chip-select rerouting conductor. This rerouting conductor extends from the package substrate to a chip pad on an upper one of the chips in the multi-chip stack. The chip-select rerouting conductor extends through a first via hole in a lower one of the chips in the multi-chip stack.

Methods of forming integrated circuit chips include forming a plurality of criss-crossing grooves in a semiconductor wafer having a plurality of contact pads thereon and filling the criss-crossing grooves with an electrically insulating layer. The electrically insulating layer is then patterned to define at least first and second through-holes therein that extend in a first one of the criss-crossing groves. The first and second through-holes are then filled with first and second through-chip connection electrodes, respectively. The semiconductor wafer is then diced into a plurality of integrated circuit chips by cutting through the electrically insulating layer in a criss-crossing pattern that overlaps with the locations of the criss-crossing grooves.

A wiring structure may include a pad, a conductive pattern and an insulating photoresist structure. The pad may be provided on a body and electrically connected to a circuit unit of the body. The conductive pattern may be provided on the body and may be electrically connected to the pad. The insulating photoresist structure may be provided on a surface of the conductive pattern. The insulating photoresist structure may have a contact hole through which the conductive pattern may be partially exposed. The insulating photoresist structure may be fabricated by providing a photosensitive photoresist film on the conductive layer, and patterning the photosensitive photoresist film by two photo processes.

A wafer level package may include a semiconductor substrate supporting an electrode pad. A first insulating layer may be provided on the semiconductor substrate. The first insulating layer may include a first opening through which the electrode pad may be exposed. A seed metal layer may be provided on an entire surface of the first insulating layer. A redistribution interconnection metal layer may be provided on the seed metal layer. A second insulating layer may be provided on the redistribution interconnection metal layer. The second insulating layer may have a second opening spaced from the first opening to expose a portion of the redistribution interconnection metal layer. The second insulating layer may surround the redistribution interconnection metal layer. An unwanted portion of seed metal layer may be removed using the second insulating layer as an etch mask.
