摘要:
An electrical connection includes a first electrical contact made of electrically conductive material. The first electrical contact is formed with a depression therein. Also included are a deformable pad, having a Young's modulus of less than 1,000,000 psi, which bears on the first contact; and a second electrical contact, made of electrically conductive material, which contacts the first electrical contact and is at least partially received into the depression. The deformable pad at least partially causes at least one lateral force on the first electrical contact, so as to induce the first electrical contact to make an electrical connection with the second electrical contact. An array of such contacts is also contemplated, as is an array of cantilevered contacts, which may or may not have depressions, and which are supported by at least one elastomeric pad, having a Young's modulus of less 72,500 psi.

Disclosed is an improved system and method for efficiently removing tissue using laser ablation. A first laser emits a first laser beam with a variable first integrated fluence sufficient to ablate tissue. The first laser beam is movably positioned over one or more surfaces of the tissue and the first integrated fluence varies over different levels with position, so different thicknesses of tissue are ablated at different surface positions in order to modify the contour of the surface of the tissue. Modifications include tissue smoothing, removing, feathering, sharpening, and roughening. In one preferred embodiment the tissue is eschar that is removed, unveiling viable tissue. In alternate preferred embodiments, one or more additional lasers beams with different wavelengths, with integrated fluence sufficient to ablate tissue, are moved over the surface of the tissue until a second ablation reaches a second self-termination point, e.g., determined by affects of chemicals below the termination point that absorb the second laser beam without producing the temperature increase necessary for ablation to continue.

The present invention relates to a method for fabricating a semiconductor device with a last level copper-to-C4 connection that is essentially free of aluminum. Specifically, the last level copper-to-C4 connection comprises an interfacial cap structure containing CoWP, NiMoP, NiMoB, NiReP, NiWP, and combinations thereof. Preferably, the interfacial cap structure comprises at least one CoWP layer. Such a CoWP layer can be readily formed over a last level copper interconnect by a selective electroless plating process.

The present invention relates to a method for fabricating a thin layer made of a alloy and having photovoltaic properties. The method according to the invention comprises first steps of: a) depositing an adaptation layer (MO) on a substrate (SUB), b) depositing at least one layer (SEED) comprising at least elements I and/or III, on said adaptation layer. The adaptation layer is deposited under near vacuum conditions and step b) comprises a first operation of depositing a first layer of I and/or III elements, under same conditions as the deposition of the adaptation layer, without exposing to air the adaptation layer.

Via stack structures are disclosed. In one embodiment, a structure includes a via stack including: a first substantially cross-shaped line in a first dielectric layer; a second substantially cross-shaped line set in a second dielectric layer, and a via stud coupling the first substantially cross-shaped line to the second substantially cross-shaped line. In another embodiment, a structure includes a first via stack, and a second via stack, wherein the first via stack and the second via stack extend in a divergent manner from one another. Each via stack structure is useful for support, for example, in under wire bond applications. The via stack structures can be mixed with other via stack structures and selectively placed within a layout to replace conventional metal plate and via stud array configurations.
