Patent ID: 7723213

Claim:
A method for manufacturing a semiconductor chip having through electrodes, comprising the steps of: forming, in a semiconductor wafer having front and back surfaces formed with circuits, a plurality of electrode forming holes for forming the through electrodes; superimposing bump forming masks formed with a plurality of bump holes over the front and back surfaces of the semiconductor wafer respectively in such a manner that the electrode forming holes and the bump holes are brought into alignment; placing the semiconductor wafer with the bump forming masks superimposed thereon over a stage; embedding conductive paste into the bump holes of the bump forming masks superimposed over the front and back surfaces and the electrode forming holes of the semiconductor wafer from the bump forming mask disposed over the surface on the side opposite to the stage, of the semiconductor wafer; detaching the bump forming masks from the semiconductor wafer after the conductive paste has been embedded; and dividing the semiconductor wafer into fractions after the bump forming masks have been detached.
