Abstract: Wire bonders and methods of wire-bonding are disclosed herein. In one embodiment, a method includes attaching a wire to a terminal of a microelectronic component and generating an arc between a first electrode and a second electrode to sever the wire at a point at least proximate to the first and second electrodes. In another embodiment, a wire bonder includes a bond head having a capillary, a first electrode and a second electrode each disposed relative to the bond head, and a controller operably coupled to the first and second electrodes. The controller has a computer-readable medium containing instructions to perform the above-mentioned method. It is emphasized that this Abstract is provided to comply with the rules requiring an abstract. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

Abstract: An apparatus and method of forming improved wire bonds between the contact pads on semiconductor devices and individual lead frame fingers of a lead frame. The present invention includes the use of an individual independent lead finger clamp during the wire bonding process to provide increased stability of the individual lead finger for improved bonding. If desired, the present invention also provides for the use of a conventional fixed clamp for the lead fingers during the wire bonding process in addition to the individual independent lead finger clamp during the wire bonding process to provide increased stability of the individual lead finger for improved bonding. The present invention also contemplates the replacement of the fixed clamp with another, or second, independent clamp in addition to the first individual independent lead finger clamp during the wire bonding process.

Abstract: A wire-bonding machine includes a heat block for supporting a lead frame during wire-bonding. A clamp mechanism in the machine clamps leads of the lead frame during wire-bonding by fixedly holding sets of the leads against the heat block one set at a time. A wire-bonding tool wire-bonds leads clamped by the clamp mechanism to bond pads on an integrated circuit die. By clamping leads of the lead frame in separate sets, the machine provides improved clamping for lead frames with leads requiring clamping in different planes.

Abstract: A condensed memory matrix is fabricated by conductively connecting the attachment bumps of a substrate with the attachment bumps of a wafer of DRAM chips and physically bonding the juxtaposed surfaces of the substrate and the wafer with a dielectric curable resin. An array of heat fins is bonded to the inactive surface of the wafer by a thermally conductive curable resin.

Abstract: An offset die stacking arrangement is disclosed having at least one upper level die having a width which is less than the distance separating the opposing bonding sites of the underlying die. The lowest die is affixed to the substrate within a recess in the substrate. The upper die is fixed above the lower die and rotated within a plane parallel to the lower die through an angle which insures that none of the bonding sites of the lower die are obstructed by the upper die. Once the dice are fixed in this manner, the entire assembly is subjected to the wire bonding process with all of the bonds being made in the same step.

Abstract: A method used to form a semiconductor device comprises providing first and second circuit portions having first and second pad portions respectively. The second circuit portion is electrically isolated from the first circuit portion. The first and second pad portions are then electrically connected, for example with a ball bond or a wire bond, to electrically couple the first and second circuit portions. In various embodiments the semiconductor device will not function until the pad portions are electrically coupled, and in other embodiments the functionality of the device may be selectively controlled by connecting selected pad portions from a plurality of pad portions. Isolating the first and second circuit portions allows electrical operations such as antifuse programming to be carried out without adversely affecting related circuits. Once electrical operations are completed, the isolated circuit portions are electrically coupled to provide a complete circuit.
