Patent ID: 7101792

Claim:
A method of placing conductive material in at least one via in a semiconductor substrate, the method comprising: providing a semiconductor substrate including at least one via extending from a backside thereof to a conductive element forming a conductive structure of the semiconductor substrate; exposing the backside of the semiconductor substrate including the at least one via to an electroplating solution while contacting a conductive surface on an active surface of the semiconductor substrate in electrical communication with the conductive element with a conductive contact pad by using the backside of the semiconductor substrate as a portion of a surface of a reservoir containing the electroplating solution; contacting at least one seal to the backside of the semiconductor substrate to retain the electroplating solution in the reservoir; and applying an electrical potential across the conductive element between the electroplating solution and the conductive contact pad to cause conductive material from the electroplating solution to deposit within the at least one via.
