Patent ID: 7934634

Claim:
A wire bonding method of bonding a wire from a first bonding point to a second bonding point, the method comprising, in the order stated, the steps of: a bump forming step of forming a bump on a die pad; wherein the first bonding point is an interconnect wiring and the second bonding point is the bump formed on the die pad; a bent portion forming step of forming a bent portion in a portion of the wire that protrudes from a tip end of a capillary by holding the wire with a clamper and bending the portion of the wire protruding from the tip end of the capillary in a direction parallel to a line joining the first and second bonding points and towards edges of a die, thereby cutting the wire from the bump; a first bonding step of bonding the bent portion directly on the first bonding point; a looping step of looping the wire between the first bonding point and the second bonding point; a second bonding step of bonding the wire on the second bonding point; a cutting step of cutting the wire from the second bonding point; and wherein the first bonding step further comprises, in the order stated, the steps of: a lower first bonding portion forming step of forming the lower first bonding portion on the interconnect wiring by bonding the bent portion of the wire; and an upper first bonding portion forming step of raising and moving the capillary above the lower first bonding portion then lowering the capillary to the lower first bonding portion.
