Low loop wire bonding

A method of coupling a first end of a bonding wire to a first contact and a second end of the bonding wire to a second contact, where an upper surface of the first contact and an upper surface of the second contact are at substantially a same height and extend substantially along a plane, the method comprising:

• forming a ball bond on the second contact using a portion of the bonding wire;
• forming a first length of the bonding wire, the first length coupled to the ball bond and extending upward from the ball bond substantially along a z-axis and curving outward away from the ball bond substantially along x and y axes in a direction towards the first contact, the x-axis extending between the first contact and the second contact and the y-axis extending perpendicular to the x and z axes;
• forming a second length of the bonding wire coupled to the first length, the second length extending from the first length downward to a first ball bond positioned on the first contact;
• and
• coupling the second length of the bonding wire to the first ball bond.

A wire bonding method in which a wire passing through a capillary is coupled between a first contact and to a second contact, the method comprising the steps of:

• forming a ball bond on the second contact;
• thereafter, while paying out a first length of the wire:
• raising the capillary vertically upward substantially along a z-axis a first distance from the ball bond;
• thereafter, moving the capillary laterally substantially along a y-axis a second distance in a direction away from the ball bond, an x-axis extending between the first contact and the second contact and the y-axis extending perpendicular to the x and z axes;
• thereafter, raising the capillary vertically upward substantially along the z-axis a third distance;
• thereafter, moving the capillary laterally substantially along the x-axis a fourth distance in a direction towards the first contact;
• thereafter, raising the capillary vertically upward substantially along the z-axis a fifth distance;
• thereafter, moving the capillary laterally substantially along the y-axis a sixth distance in a direction towards the ball bond;
• thereafter, moving the capillary downward to the first contact;
• and
• thereafter, coupling the wire to the first contact.
