Method for producing semiconductor substrate

摘要

To provide a method for producing a semiconductor substrate able to uniformly and quickly fill through-holes in the semiconductor substrate with conductive material. This method comprises a process for forming through-holes (14) in a substrate (10), a process for disposing solder (42) on one surface of the substrate, and a process for pressing the solder on a side of the substrate by a press (40) and heat-melting the solder to fill the through-holes in the substrate with the solder.
