Patent ID: 6932262

Claim:
A bonding apparatus for a semiconductor chip, comprising: ultrasonic vibration generating unit which applies an ultrasonic vibration to a contact region where a bonding portion of said semiconductor chip is in contact with a bonding portion of another part to be bonded to said semiconductor chip, via a mount tool for holding said semiconductor chip, so that said ultrasonic vibration increases a die shear strength that is a shear strength of an entire bonding region to be formed between said semiconductor chip and said part which are to be bonded in an ultrasonic-vibration-axial direction; holding force control unit which controls vibration-axial directional holding force or a shear strength of an entire contact interface of said semiconductor chip to be held by said mount tool and said mount tool in said ultrasonic-vibration-axial direction; inertial force control unit which controls inertial force in said ultrasonic-vibration-axial direction, which is generated on said semiconductor chip to be held by said mount tool by said ultrasonic vibration; and control management unit which maintains a relationship of (vibration-axial directional holding force)>(die shear strength)+(inertial force).
