    摘要: A process for reworking of PGA chip carriers where one or more I/O pins is unplated. The process includes electrolytically etching the I/O pins which removes any corrosion product from the unplated I/O pins and removes the top gold layer from the remaining I/O pins. The etchant includes a metal-providing compound selected from the group consisting of a silver salt, copper cyanide, silver cyanide, gold cyanide or mixtures thereof, at a concentration in the range from about 2.7 to about 4.1 g/l as metal; potassium or sodium carbonate at a concentration in the range from about 10 to about 100 g/l; and potassium or sodium cyanide at a concentration in the range from about 29 to about 35 g/l.

    摘要: A through-silicon via (TSV) structure forming a unique coaxial or triaxial interconnect within the silicon substrate. The TSV structure is provided with two or more independent electrical conductors insulated from another and from the substrate. The electrical conductors can be connected to different voltages or ground, making it possible to operate the TSV structure as a coaxial or triaxial device. Multiple layers using various insulator materials can be used as insulator, wherein the layers are selected based on dielectric properties, fill properties, interfacial adhesion, CTE match, and the like. The TSV structure overcomes defects in the outer insulation layer that may lead to leakage. A method of fabricating such a TSV structure is also described.

    摘要: An etching method. The method includes etching a first plurality of silicon wafers in a first enchant, each silicon wafer having SiO2 and Si3N4 deposited thereon, where the etching includes dissolving a quantity of the SiO2 and a quantity of the Si3N4 in the first echant. A quantity of insoluble SiO2 precipitates. A ratio of a first etch rate of Si3N4 to a first etch rate of SiO2 is determined to be less than a predetermined threshold. A portion of the first etchant is combined with a second etchant to form a conditioned etchant. A second plurality of silicon wafers is etched in the conditioned etchant. A ratio of a second etch rate of Si3N4 to a second etch rate of SiO2 in the conditioned etchant is greater than the threshold. A method for exchanging an etching bath solution and a method for forming a selective etchant are also disclosed.
