A method for forming a through-silicon via includes the steps of defining a groove in each chip of a wafer which has a plurality of semiconductor chips; applying liquid polymer on the wafer to fill the groove; forming an insulation layer on a sidewall of the groove through patterning the polymer; forming a metal layer to fill the groove which is formed with the insulation layer on the sidewall thereof; and back-grinding a backside of the wafer to expose the metal layer filled in the groove. |
