摘要： A stereolithographic method and apparatus for forming polymeric structures comprising a plurality of overlying layers, each layer formed by polymerizing a thin layer of liquid photopolymer on a prior layer. Crevices formed at the layer interfaces are filled by a stereolithographic method comprising lifting the multilayered structure from the liquid photopolymer, draining excess liquid therefrom, tilting the structure to provide an acute angle of incidence between an incident radiation beam and a side wall of the object, and applying radiation to the crevice to polymerize at least the surface of a quantity of liquid photopolymer therein. The structure may then be subjected to a separate final full cure to fully harden the structure. An exemplary use is the packaging of electronic components and the like.

摘要： A chip carrier for temporarily connecting a semiconductor chip to a testing device. The chip carrier includes a substrate having a first set of contact points for electrically engaging the testing device and a second set of contact points to be connected with the contact elements of the semiconductor chip. The semiconductor chip is disposed on the substrate and is substantially covered by a cover member. One or more clips are in contact with the cover member and are used to secure the semiconductor chip in position. The clips have a first member removably attached to the substrate and a second member separated from the first member and in contact with the cover member. As the second member is displaced from an unstressed position, a force is generated by the clip and transferred to the cover member and the semiconductor chip. The chip carrier reliably secures the semiconductor chip while occupying a relatively small space over the semiconductor chip.

摘要： A method and apparatus for electrolytic plating of selected areas of printed circuit board traces is disclosed. The method is characterized by its elimination of the need for plating bus bars and plating contacts on the printed circuit board to facilitate a spot-plating process. In one embodiment, a printed circuit board substrate is provided which is at least partially conductive, such that a plating voltage may be applied to any one or more points on the substrate during a spot plating operation. In another embodiment, the substrate material is initially partially conductive, but following the spot-plating operation, is subjected to a curing treatment or the like to cause degeneration of the substrate's conductivity. Carbon-impregnated polyimide, partially-cured polyimide, FR4 or FR5, with appropriate contaminants introduced therein are contemplated as materials suitable for a printed circuit board substrate in accordance with the invention. In another embodiment, the traces are first applied to the partially conductive substrate by an electroplating operation wherein an electroplating voltage is applied to the substrate such that the substrate itself serves as one terminal of the electroplating system.

摘要： A BGA test socket for use in standard testing and burn-in testing of BGA dies and method for testing such dies is disclosed wherein a die contact insert made of silicon or ceramic using standard IC fabrication technology is used. Through using such an insert, even small scale (pitch) BGA dies can be reliably tested including chip scale packaged (“CSP”) BGA dies. Furthermore, using such an insert allows a conventional socket to be adapted for use with a wide variety of both BGA dies and other varieties. A method for using the device is disclosed which overcomes current static electricity problems experienced in testing CSP BGA dies through closing the test socket before removing the die deposit probe.

摘要： A machine and method for bonding puncture-type conductive contact members of an interconnect to the bond pads of a bare semiconductor die includes the use of one or two ultrasonic vibrators mounted to vibrate one or both of the die and interconnect. A short axial linear burst of ultrasonic energy enables the contact members to pierce hard oxide layers on the surfaces of the bond pads at a much lower compressive force and rapidly achieve full penetration depth.

摘要： A semiconductor package includes a substrate and a semiconductor die wire bonded, or alternately flip chip bonded, to the substrate. The substrate includes three separate layers including a conductive layer having a pattern of conductive traces, a first insulating layer covering the conductive traces, and a second insulating layer covering the die. The insulating layers also include planar surfaces having external contacts, and conductive vias in electrical communication with the external contacts and with the conductive traces. The external contacts have matching patterns, such that the package can be stacked on a substantially identical package to form a stacked electronic assembly. In addition, the packages in the stacked assembly can have different circuit configurations, and can perform different functions in the assembly. A method for fabricating the package includes the steps of providing the conductive layer having the conductive traces, attaching the die to the conductive traces, forming the first insulating layer on the conductive layer, forming the second insulating layer on the die, forming the conductive vias through the insulating layers, and then forming the external contacts on the planar surfaces of the insulating layers.

摘要： A stereolithographically fabricated, substantially hermetic package surrounds at least a portion of a semiconductor die so as to substantially hermetically seal the same. Stereolithographic processes may be used to fabricate at least a portion of the substantially hermetic package from thermoplastic glass, other types of glass, ceramics, or metals. The substantially hermetic package may be used with semiconductor device assemblies or with bare or minimally packaged semiconductor dice, including dice that have yet to be singulated from a wafer. The stereolithographic method may include use of a machine vision system including at least one camera operably associated with a computer controlling a stereolithographic application of material so that the system may recognize the position, orientation, and features of a semiconductor device assembly, semiconductor die, or other substrate on which the substantially hermetic package is to be fabricated.
