Title: Die bonding method and die bonding apparatus
Inventor: PARK JONG SUNG
IPC: H01L21/677
Filed: 2019-08-06
Abstract: A die bonding method and a die bonding apparatus are disclosed. A die on a dicing tape is picked up in a non-contact manner through air blowing and vacuum suction by a picker so that a front surface of the die does not come into contact with the picker. The picked up die is transferred onto a bonding head. After vacuum adsorbing a back surface of the die, the bonding head is inverted so that the front surface of the die faces downward, and the inverted die is bonded onto the substrate due to the downward movement of the bonding head. As described above, since the die is picked up in a non-contact manner and transferred to the bonding head, contamination of the die caused by contact with the picker can be prevented.
