摘要： An actuator scaled to macroscopic or microscopic sizes, uses ultrasonic energy to induce motion of an object in a desired direction. The actuator includes one or more pair of piezoelectric transducers connected with a transducer tip. Supplying the piezoelectric transducers with alternating current electrical power causes the tip to vibrate at ultrasonic frequencies. Urging the vibrating tip into contact with a surface on the object at a selected angle of inclination induces the object to move in the desired direction at a rate determined by the inclination angle. Multiple actuators can be used to induce a fall range of movements of variously shaped objects. In microscopic form, the actuator can be used to create a MEMS device. The optional application of a compliant material either on the transducer tip or on the object's surface enhances the movement induced by the actuator.

摘要： An apparatus and a method for filling high aspect ratio holes in electronic substrates that can be advantageously used for filling holes having aspect ratios larger than 5:1 are disclosed. In the apparatus, a filler plate and a vacuum plate are used in conjunction with a connection means such that a gap is formed between the two plates to accommodate an electronic substrate equipped with high aspect ratio via holes. The filler plate is equipped with an injection slot while the vacuum plate is equipped with a vacuum slot such that when a substrate is sandwiched therein, via holes can be evacuated of air and injected with a liquid simultaneously from a bottom side and a top side of the substrate. The present invention novel apparatus and method allows the filling of via holes that have small diameters, i.e., as small as 10 &mgr;m, and high aspect ratios, i.e., at least 5:1 to be filled with an electrically conductive material such as a solder or a conductive polymer such that vias or interconnects can be formed in electronic substrates. The present invention apparatus and method can be advantageously used in fabricating substrates for display panels by forming conductive vias and interconnects for placing a voltage potential on pixel display elements formed on the display panels.

摘要： 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 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.

摘要： 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： Multiple injections of molten solder are employed to form double solder bumps having outer layers that melt at lower temperatures than the inner portions thereof. During a flip chip assembly process, the reflow temperature is above the melting temperature of the outer layers and below the melting temperature of the inner portions of the solder bumps. As the inner portions of the solder bumps do not collapse during reflow, a flip chip assembly can be made at relatively low temperatures and have a high stand-off height. A structure having double solder bumps facilitates flip chip assembly.

摘要： A flexible unitary mask has a plurality of through holes. A substrate has a plurality of wettable pads in recessed regions defining volumes. The through holes are aligned with the wettable pads. Molten solder is directly injected through the through holes of the flexible unitary mask into the volumes with the wettable pads, such that the through holes and the volumes with the wettable pads are filled with solder. The solder is allowed to solidify, forming a plurality of solder structures adhered to the wettable pads. The flexible unitary mask is peeled from the substrate after the solder has solidified.

摘要： A portion of compliant material includes four walls defining a slot. The slot has a relatively large cross-section end in fluid communication with a solder reservoir, and also has a relatively small cross-section end opposed to the relatively large cross-section end. The slot has a generally elongate rectangular shape when viewed in plan, with a length perpendicular to a scan direction, a width, parallel to the scan direction, associated with the relatively large cross section end, and a width, parallel to the scan direction, associated with the relatively small cross section end. The slot is configured in the portion of compliant material such that the relatively small cross-section end of the slot normally remains substantially closed, but locally opens sufficiently to dispense solder from the reservoir when under fluid pressure and locally unsupported by a workpiece. Methods of operation and fabrication are also disclosed.
摘要翻译：柔性材料的一部分包括限定槽的四个壁。狭槽具有与焊料储存器流体连通的相对较大的横截面端，并且还具有与相对大的横截面端相对的相对较小的横截面端。当在平面中观察时，狭槽具有大致细长的矩形形状，其垂直于扫描方向的长度，与扫描方向平行的宽度，与相对大的横截面端相关联，并且平行于扫描方向的宽度，与相对较小的截面端相关联。狭槽配置在柔性材料的部分中，使得狭槽的相对小的横截面端部通常保持基本上闭合，但是当处于流体压力下并且局部地不被工件支撑时，局部开口足够地从储存器分配焊料。还公开了操作和制造方法。
