Abstract: A method of forming a plurality of individual semiconductor chip modules wherein a plurality of chips are placed in a plurality of chip compartments formed by adhering a support panel to the first surface and a cover panel to the second surface of a stiffener panel having openings defining sidewalls of the chip compartments. The resulting laminated panel structure is then cut into a plurality of modules each having at least one compartment containing at least one chip. Each chip is electrically connected to interior conductive pads on the inner surface of the support panel, and these interior pads in turn are connected by conductive paths to exterior conductive terminals deposited on the outer surface of the support panel. The electrical connections between the chip and the interior conductive pads of the support panel may be encapsulated in a polymeric material before the cover panel is adhered to the stiffener panel.

Abstract: An electrical structure, and associated method of fabrication, for reducing thermally induced strain in a structure that couples a first conductive body of a first substrate to a second conductive body of a second substrate (e.g., a chip to a chip carrier; a chip carrier to a circuit card). The melting point of the first conductive body exceeds the melting point of the second conductive body. The second conductive body may include eutectic lead-tin alloy, while the first conductive body may include non-eutectic lead-tin alloy. A portion of the first conductive body is coated with, or volumetrically surrounded by, a material that is nonsolderable and nonconductive. The first and second conductive bodies are coupled mechanically and electrically by surface adhesion at an uncoated portion of the first conductive body, by application of a temperature that lies between the melting points of the first and second conductive bodies.

Abstract: An attachment structure, and an associated method and system for forming the attachment structure. An end of an optical fiber is melted while the end is above, but not touching, an exposed surface of a substrate such that said end becomes molten. The optical fiber is substantially optically transparent to laser radiation of a given wavelength. The molten end is moved toward the exposed surface of the substrate until the end makes physical contact with the exposed surface of the substrate. The moving is performed sufficiently fast so that the end is still molten when the end initially makes the physical contact with the exposed surface of the substrate. The physical contact is maintained for a sufficient length of time to enable the end to bond to the exposed surface of the substrate with no intervening matter between the end and the exposed surface of the substrate.

Abstract: Under the present invention, a contaminant capturing material is positioned within a disk drive. Specifically, the contaminant capturing material is positioned on a suspension, adjacent a slider that hovers proximate a disk within the disk drive when the disk is in rotation. The contaminant capturing material will prevent contaminants from contacting the disk and thereby causing damage. In addition, a set of porous, open celled filters that are coated with the contaminant capturing material can also be provided. If used, the open celled filters are positioned adjacent the disk within an air stream created by a rotation of the disk.
