摘要:
In a process of manufacturing a core substrate of a semiconductor package using a metal core, through holes are formed in required positions on the metal core by an etching or a punching. Then, surfaces of the metal core inclusive of inner walls of the through holes are filled with insulative resin by an electrophoretic deposition process so as to form resin films. Thereafter, conductive thin films are formed on the entire surfaces of the resin films and the insides of the through holes are filled with a conductive material.
