How are vias made

In integrated circuit (IC) design, a via is a small opening in an insulating oxide layer that allows a conductive connection between different layers. A via on an integrated circuit that passes completely through a silicon wafer or die is called a through-chip via or through-silicon via (TSV). Through-glass vias (TGV) have been studied by Corning Glass for semiconductor packaging, due to the reduced electrical loss of glass versus silicon packaging. A via connecting the lowest laye… WebIn general terms, a via connects one PCB layer to another. Vias may join traces, pads and other conductive elements on a PCB through a copper cylinder placed inside holes. These holes pass through the affected layers on the board. PCB Vias need a certain volume of copper on a layer to ensure that the layers are really connected.
