  • Patent number: 7154605
    Abstract: A method is described for characterizing defects on a test surface of a semiconductor wafer using a confocal-microscope-based automatic defect characterization (ADC) system. The surface to be tested and a reference surface are scanned using a confocal microscope to obtain three-dimensional images of the test and reference surfaces. The test and reference images are converted into sets of geometric constructs, or “primitives,” that are used to approximate features of the images. Next, the sets of test and reference primitives are compared to determine whether the set of test primitives is different from the set of reference primitives. If such a difference exists, then the difference data is used to generate defect parameters, which are then compared to a knowledge base of defect reference data. Based on this comparison, the ADC system characterizes the defect and estimates a degree of confidence in the characterization.

  • Patent number: 7132301
    Abstract: Techniques for identifying, locating, detecting, and reviewing voltage contrast defects are described. A system for implementing the present invention includes a charged particle beam defect review system with one or more installed electron flood guns. In order to review a semiconductor specimen, an entire semiconductor wafer or a sub-region of a wafer is flooded with electrons from the flood gun(s) so that the wafer surface is charged to a certain voltage level. Flooding the specimen greatly enhances the effect of voltage contrast review techniques and therefore manifests voltage contrast defects that would not appear otherwise. The inventive techniques can also be applied so that a review system can be used to inspect at least a portion of a semiconductor wafer. Techniques for controlling the amount of negative charge applied to the specimen are also described.

  • Patent number: 7109124
    Abstract: A solid state electronically steerable antenna can be generated from a sheet of semiconductor material by forming a pattern of localised plasma regions in the sheet, either by injecting carriers into, or by generating carriers in, those localised regions. A suitable solid state plasma antenna can be made from a silicon wafer (10) by first thermally oxidising the surfaces and subjecting the wafer (10) to a high temperature stabilisation process to improve the stoichiometry at the silicon/silica interface, and optionally also performing a low-temperature bake in a gas mixture including hydrogen. This produces a wafer (10) with a long minority carrier lifetime. Regions of the wafer (10) in which plasma may be generated are then defined by reticulation to form isolated regions with high minority carrier lifetime. The resulting discrete regions may be of a size less than 1 mm, for example 0.3 mm.

  • Patent number: 7098071
    Abstract: The present invention relates to a method for flip chip bonding by utilizing an interposer with embedded bumps. The method comprises (a) providing a first element having a first surface; (b) forming an interposer onto the first surface; (c) forming a plurality of openings on the interposer; (d) forming a plurality of bumps in the openings, wherein the height of the bumps is smaller than the depth of the openings; (e) providing a second element having a plurality of pre-solders; and (f) bonding the first surface onto the second element, so that the pre-solders are disposed in the openings and in contact with the bumps. As a result, the self-alignment between the pre-solders and the bumps can avoid the shift between the first element and the second element.

  • Patent number: 7033861
    Abstract: A combination composed from a form standard and a CSP is attached to flex circuitry. Solder paste is applied to first selected locations on the flex circuitry and adhesive is applied to second selected locations on the flex circuitry. The flex circuitry and the combination of the form standard and CSP are brought into proximity with each other. During solder reflow operation, a force is applied that tends to bring the combination and flex circuitry closer together. As the heat of solder reflow melts the contacts of the CSP, the combination collapses toward the flex circuitry displacing the adhesive as the solder paste and contacts merge into solder joints. In a preferred embodiment, the form standard will be devised of heat transference material, a metal, for example, such as copper would be preferred, to improve thermal performance. In other embodiments, the methods of the invention may be used to attach a CSP without a form standard to flex circuitry.

  • Patent number: 7022583
    Abstract: A method of forming a shallow trench isolation device in order to prevent kick effects comprising a semiconductor structure having a patterned masking layer formed thereon. A shallow trench is formed in the semiconductor structure by using the patterned masking layer as a mask. A liner oxide layer and a doped dielectric layer are formed in sequence on the semiconductor structure to cover the surface of the shallow trench. A layer of oxide is formed on the semiconductor structure to fill the shallow trench. The dopants in the doped dielectric layer diffuse into the semiconductor structure surrounding the shallow trench to form an ion doped area, thereby increasing the threshold voltage caused by the recess on the corner structure in order to prevent the kick effect.
