Stackable pipette tips having increased accuracy are provided through a unique pipette tip comprising a collar, a barrel and an acutely tapered neck transitioning between the collar portion and the barrel portion. The pipette tip of the present invention has a significant reduction of inner volume resulting from the acute taper and several other tapers along the inner surface. This reduction of inner volume provides a tip with greater accuracy, as less air must be displaced in order to aspirate and dispense small aliquots of liquid. The pipette tips of the present invention also are directly stackable in a rack on one another without interaction causing lodging, binding or clinging between the outer surface of the top or stacked tip and the inner surface of the base or bottom tip.

A die bonder contains a bonding tool (24), a strobe (34), a camera (32), and a shank (20). The bonding tool (24) has the following: a tip suction surface (27) that holds a semiconductor die (30) by suction; a base that is wider than said tip suction surface (27); and a sloped surface that connects the suction surface (27) to the base and is sloped with respect to a lengthwise centerline. The camera (32) simultaneously acquires an image of the semiconductor die (30) held by the suction surface (27), an image of the shank (20), and an image of the sloped surface of the bonding tool (24). The shank (20) is in contact with the base of the bonding tool (24), is separated from the suction surface (27) by a distance greater than the depth of focus of the camera (32) in the lengthwise direction of the bonding tool (24), does not move relative to the bonding tool (24), and reflects light from the strobe (34). Misalignment between a semiconductor die and a bonding tool in a die bonder can thus be detected effectively with a simple configuration.
