Method for depositing a metallic material on an aluminum alloy surface for galvanic displacement type deposition, electrodeposition or electroless deposition of a metallic film on the surface wherein the alloy surface is oxidized (e.g. anodized) to form aluminum oxide and the oxidized surface is etched to leave a partial thickness of a barier aluminum oxide on the alloy surface. The partial thickness of the barrier oxide is controlled by etching to form a porous, metallic particulate film for a thin barrier oxide, or a continuous metallic film for thicker barrier oxide. The metallic film then is electrodeposited or electroless deposited on the barrier film.

A partial-via-first dual-damascene method using a tri-layer resist method forms a first via hole through partial thickness of a dielectric layer, and forms a tri-layer resist structure on the dielectric layer to fill the first via hole with the bottom photoresist layer. A dry development process is performed to transfer a first opening on the top photoresist layer to the middle layer and the bottom photoresist layer, and expose the first via hole again, and remove the top photoresist layer. A dry etching process is then performed to form a second via hole under the first via hole and a trench over the second via hole. Finally a wet striping process is used to remove the remainder of the photoresist layer.

A tendon repair implant for treatment of a complete or partial thickness tear in the supraspinatus tendon of the shoulder is provided. The implant may incorporate features of rapid deployment and fixation by arthroscopic means that compliment current procedures; tensile properties that result in desired sharing of anatomical load between the implant and native tendon during rehabilitation; selected porosity and longitudinal pathways for tissue in-growth; sufficient cyclic straining of the implant in the longitudinal direction to promote remodeling of new tissue to tendon-like tissue; and, may include a bioresorbable construction to provide transfer of additional load to new tendon-like tissue and native tendon over time.

The present invention is related to compositions comprising decellularized cartilage tissue powder in the forms of paste, putty, hydrogel, and scaffolds, methods of making compositions, and methods of using these compositions for treating osteochondral defects and full- or partial-thickness cartilage defects.

A cavity unit of an ink-jet printhead is formed by laminating a base plate formed with pressure chambers, a spacer plate, a manifold plate, a damper plate, a cover plate, and a nozzle plate formed with nozzles. The manifold plate is formed with a manifold chamber that penetrates through the manifold plate. The damper plate is formed with a recess on a side facing away from the manifold chamber and a damper wall left on a side facing the manifold chamber to have a partial thickness of the damper plate. The damper plate is bonded to the manifold plate on an opposite side from the base plate such that the damper wall is positioned to face the manifold chamber. The cover plate is bonded to the manifold plate to seal the recess. Because the damper plate is relatively thick while the damper wall is thin enough to absorb a pressure wave in the manifold chamber generated upon ink ejection, the damper plate is easy to handle.
