摘要:
Apparatus and methods of fabricating an under bump metallization structure including an adhesion layer abutting a conductive pad, a molybdenum-containing barrier layer abutting the adhesion layer, a wetting layer abutting the molybdenum-containing barrier layer, and high tin content solder material abutting the wetting layer. The wetting layer may be substantially subsumed in the high content solder forming an intermetallic compound layer. The molybdenum-containing barrier layer prevents the movement of tin in the high tin content solder material from migrating to dielectric layers abutting the conductive pad and potentially causing delamination and/or attacking any underlying structures, particularly copper structures, which may be present.

According to one aspect of the invention, a method for forming contact formations is provided. A substrate may be placed in an electrolytic solution. The substrate may have an exposed conductive portion and the electrolytic solution may include a plurality of metallic ions and an accelerator. The accelerator may include at least one of bis-(sodium sulfopropyl)-disulfide and 3-mercapto-1-propanesulfonic acid-sodium salt. A voltage may be applied across the electrolytic solution and the conductive portion of the substrate to cause the metallic ions to be changed into metallic particles and deposited on the conductive portion. The electrolytic solution may also include a protonated organic additive. The electrolytic solution may also include an acid and a surfactant. The acid may include at least one of sulfuric acid, methane sulfonic acid, benzene sulfonic acid, and picryl sulfonic acid. The surfactant may include at least one of polyethylene glycol and polypropylene glycol.

A 3D interconnect structure and method of manufacture are described in which metal redistribution layers (RDLs) are integrated with through-silicon vias (TSVs) and using a single damascene type process flow. A silicon nitride or silicon carbide passivation layer may be provided between the thinned device wafer back side and the RDLs to provide a hermetic barrier and polish stop layer during the process flow.

A 3D interconnect structure and method of manufacture are described in which a through-silicon vias (TSVs) and metal redistribution layers (RDLs) are formed using a dual damascene type process flow. A silicon nitride or silicon carbide passivation layer may be provided between the thinned device wafer back side and the RDLs to provide a hermetic barrier and etch stop layer during the process flow.

A method and apparatus for masking and unmasking content. A system configured to practice the example method embodiment parses a markup language document to identify a location of a section of the markup language document to mask and selects, based on a content type for content within the section, replacement content for the section. Then the system saves a copy of the section in a storage external to the markup language document. The system inserts the replacement content in the markup language document at the location in place of the section to mask the section while preserving formatting and layout of the markup language document. Upon receiving an indication to restore the section, the system inserts the copy of the section in the markup language document at the location in place of the replacement content.
摘要:
An archery bow holding device that is preferably mounted to a ball joint assembly for attachment to a table top, bench or like surface, and provides a movable mount for the archery bow holding device that holds an archery bow for performing work thereon. The preferred ball joint assembly includes a cylindrical housing that is slotted on opposite sides thereof from a center opening in the housing top and contains a ball that mounts a stem that the archery bow holding device is secured to, with the stem fitted through a slot through the housing top, to tilt between the slots and pivot when the ball in unlocked and, with the ball locked, provides a rigid mount to the archery bow holding device that includes a main beam that is bent to provide a rest for an archery bow limb positioned and clamped there against for an operator to work on.
