Abstract: 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.
