Abstract

PURPOSE: To prevent an electric circuit element from damaging due to load concentration or the like by bonding the conductive leads of a tape carrier to the element by spraying heated gas thereto to thereby equalize the pressing strength on the leads over the entire leads.
CONSTITUTION: A semiconductor device 2 provided with a bump and completely diced in wafer type is set on a table. After a carrier tape or thin lead frame 4 is disposed to position the device on the table, heated gas 5 at necessary temperature for bonding is sprayed through a jig 20 under pressure necessary for the bonding toward the lead 4 and the surface of the device 2. When the bonding is completed, room temperature gas is mixed in the heated gas 5 to thereby lower the temperature at the connecting portion to thus complete the bonding method. This method is particularly advantageous for the thin lead frame such as carrier tape, flat package, or the like.
