Methods of forming a conductive structure on a substrate prior to packaging, and a test probe structure generated according to the method, are disclosed. The conductive structure includes a high aspect ratio structure formed by injected molded solder. The invention can be applied to form passive elements and interconnects on a conventional semiconductor substrate after the typical BEOL, and prior to packaging. The method may provide better electromigration characteristics, lower resistivity, and higher Q factors for conductive structures. In addition, the method is backwardly compatible and customizable.
摘要:
A method for forming a space transformer (and a space transformer formed by the method) having a first plate and a second plate, the plates being separated by a frame, and electrical connectors for providing electrical connections between electrical contacts which are relatively closely spaced on the first plate and relatively more widely spaced on the second plate. The method comprises attaching first ends of wires to first electrically conductive regions on the first plate; forming insulating layers over the wires; forming electrically conductive coverings over the insulating layers; and connecting second ends of the wires to second electrically conductive regions on the second plate.

A method for testing integrated circuit chips with probe wires on flat solder bumps and IC chips that are equipped with flat solder bumps are disclosed. In the method, an IC chip that has a multiplicity of bond pads and a multiplicity of flat solder bumps are first provided in which each of the solder bumps has a height less than ½ of its diameter on the multiplicity of bond pads. The probe wires can thus be easily used to contact the increased target area on the solder bumps for establishing electrical connection with a test circuit. The probe can further be conducted easily with all the Z height of the bumps are substantially equal. The height of the solder bumps may be suitably controlled by either a planarization process in which soft solder bumps are compressed by a planar surface, or solder bumps are formed in an in-situ mold by either a MSS or an electroplating process for forming solder bumps in the shape of short cylinders. When the MSS method is used for planting the bumps, solder bumps are transferred onto the wafer surface in a substantially flattened hemi-spherical shape.

A process is described for forming a common input-output (I/O) site that is suitable for both wire-bond and solder bump flip chip connections, such as controlled-collapse chip connections (C4). The present invention is particularly suited to semiconductor chips that use copper as the interconnection material, in which the soft dielectrics used in manufacturing such chips are susceptible to damage due to bonding forces. The present invention reduces the risk of damage by providing site having a noble metal on the top surface of the pad, while providing a diffusion barrier to maintain the high conductivity of the metal interconnects. Process steps for forming an I/O site within a substrate are reduced by providing a method for selectively depositing metal layers in a feature formed in the substrate. Since the I/O sites of the present invention may be used for either wire-bond or solder bump connections, this provides increased flexibility for chip interconnection options, while also reducing process costs.
摘要:
A method of manufacturing integrated circuits wherein a conductive structure in a topmost semiconductive layer of an integrated circuit is provided having a thickness greater than or equal to 1.5 &mgr;m. The thickness of the conductive structure is sufficiently great as to effectively protect any layers beneath the topmost semiconductive layer from damage from pressure, such as pressure applied by testing probes. In a preferred embodiment, traditional aluminum TD leveling is discarded in favor of gold deposited upon the thickened conductive layer.
摘要:
Silicon and germanium containing materials are used at surface of conductors in electronic devices. Solder can be fluxlessly bonded and wires can be wire bonded to these surfaces. These material are used as a surface coating for lead frames for packaging integrated circuit chips. These materials can be decal transferred onto conductor surfaces or electrolessly or electrolytically disposed thereon.
摘要:
An apparatus and a method for simultaneously testing or burning in all the integrated circuit chips on a product wafer. The apparatus comprises a glass ceramic carrier having test chips and means for connection to pads of a large number of chips on a product wafer. Voltage regulators on the test chips provide an interface between a power supply and power pads on the product chips, at least one voltage regulator for each product chip. The voltage regulators provide a specified Vdd voltage to the product chips, whereby the Vdd voltage is substantially independent of current drawn by the product chips. The voltage regulators or other electronic means limit current to any product chip if it has a short. The voltage regulator circuit may be gated and variable and it may have sensor lines extending to the product chip. The test chips can also provide test functions such as test patterns and registers for storing test results.

A spring array connector includes a unitary resilient layer of multiple springs having a layer of multiple electrically conducting lines, electrical contacts and electrical terminals. Each spring of the array is independently bendable and each of the conducting lines is electrically isolated from the other conducting lines. All of the springs in the spring array are fabricated simultaneously. Spring embodiments include sine, helix, cantilever and buckling beam shapes in sheet and wire forms.

Improved via-filling compositions for producing conductive vias in circuitized ceramic substrates, particularly multilayer substrates, without cracking and/or loss of hermetic sealing. The via-filling compositions comprise pastes containing a mixture of (a) ceramic and/or glass spheres of substantially- uniform diameter between about 0.5 and 6 .mu.m, (b) conductive metal particles or spheres having a maximum dimension or diameter between about 1/3 and 1/4 of the diameter of the ceramic and/or glass spheres, and (c) a binder vehicle. The formed conductive via bodies comprise a uniform conductive skeletal network of sintered metal particles densely packed within a uniform matrix of the co-sintered ceramic and/or glass spheres, which matrix is hermetically fused and integrated with ceramic layers forming the wall of the via in the ceramic circuit substrate.
