  • Patent number: 7340828
    Abstract: There is provided a method for producing a metal/ceramic bonding circuit board, which can form a fine pattern even if a circuit forming metal plate is thick and which can shorten the time required to carry out etching, when a molten metal is caused to contact to a ceramic substrate to be cooled and solidified to bond the circuit forming metal plate to the ceramic substrate to etch the circuit forming metal plate to form a metal circuit plate having a desired circuit pattern. A molten metal is caused to contact both sides of a ceramic substrate 10 to be cooled and solidified. Thus, a circuit forming metal plate 12 having a shape similar to a desired circuit pattern is bonded to one side of the ceramic substrate 10, and a metal base plate 14 is bonded to the other side thereof.
