Abstract
A screen printing method of conductive material is applied to a wafer with a conductive surface thereon. A dielectric layer on the wafer exposes the conductive surface to a first opening. A mask formed on the dielectric layer has a plurality of second openings corresponding to the first opening. The conductive surface is exposed by the second openings. The conductive surface is covered with a conductive material that flows into the first opening through the second openings. Then the mask is removed. With the arrangement and dimension control of the second openings, the conductive material easily flows into the first opening and is not over-scraped.
