  • Patent number: 8373270
    Abstract: In the current manufacturing process of LSI, or semiconductor integrated circuit device, the step of assembling device (such as resin sealing step) is normally followed by the voltage-application test (high-temperature and high-humidity test) in an environment of high temperature (such as an approximate range from 85 to 130° C.) and high humidity (such as about 80% RH). For that test, the inventors of the present invention found the phenomenon of occurrence of separation of titanium nitride film as the anti-reflection film from upper film and of generation of cracks in the titanium nitride film at an edge part of upper surface of the aluminum-based bonding pad applied with a positive voltage during the high-temperature and high-humidity test caused by an electrochemical reaction due to moisture incoming through the sealing resin and the like to generate oxidation and bulging of the titanium nitride film.

  • Patent number: 8373271
    Abstract: An interconnect structure is provided that includes at least one patterned and cured photo-patternable low k material located on a surface of a patterned and cured oxygen-doped SiC antireflective coating (ARC). A conductively filled region is located within the at least one patterned and cured photo-patternable low k material and the patterned and cured oxygen-doped SiC ARC. The oxygen-doped SiC ARC, which is a thin layer (i.e., less than 400 angstroms), does not produce standing waves that may degrade the diffusion barrier and the electrically conductive feature that are embedded within the patterned and cured photo-patternable low k dielectric material and, as such, structural integrity is maintained. Furthermore, since a thin oxygen-doped SiC ARC is employed, the plasma etch process time used to open the material stack of the ARC/dielectric cap can be reduced, thus reducing potential plasma damage to the patterned and cured photo-patternable low k material.

  • Patent number: 8242012
    Abstract: Disclosed are embodiments of a structure having a metal layer with top surface and sidewall passivation and a method of forming the structure. In one embodiment, a metal layer is electroplated onto a portion of a seed layer at the bottom of a trench. Then, the sidewalls of the metal layer are exposed and, for passivation, a second metal layer is electroplated onto the top surface and sidewalls of the metal layer. In another embodiment, a trench is formed in a dielectric layer. A seed layer is formed over the dielectric layer, lining the trench. A metal layer is electroplated onto the portion of the seed layer within the trench and a second metal layer is electroplated onto the top surface of the metal layer. Thus, in this case, passivation of the top surface and sidewalls of the metal layer is provided by the second metal layer and the dielectric layer, respectively.

  • Patent number: 8232655
    Abstract: An electroless Cu layer is formed on each side of a packaging substrate containing a core, at least one front metal interconnect layer, and at least one backside metal interconnect layer. A photoresist is applied on both electroless Cu layers and lithographically patterned. First electrolytic Cu portions are formed on exposed surfaces of the electroless Cu layers, followed by formation of electrolytic Ni portions and second electrolytic Cu portions. The electrolytic Ni portions provide enhanced resistance to electromigration, while the second electrolytic Cu portions provide an adhesion layer for a solder mask and serves as an oxidation protection layer. Some of the first electrolytic Cu may be masked by lithographic means to block formation of electrolytic Ni portions and second electrolytic Cu portions thereupon as needed. Optionally, the electrolytic Ni portions may be formed directly on electroless Cu layers.

  • Publication number: 20120181636
    Abstract: Methods of forming contacts (and optionally, local interconnects) using an ink comprising a silicide-forming metal, electrical devices such as diodes and/or transistors including such contacts and (optional) local interconnects, and methods for forming such devices are disclosed. Electrical devices, such as diodes and transistors may be made using such printed contact and/or local interconnects. A metal ink may be printed for contacts as well as for local interconnects at the same time, or in the alternative, the printed metal can act as a seed for electroless deposition of other metals if different metals are desired for the contact and the interconnect lines. This approach advantageously reduces the number of processing steps and does not necessarily require any etching.

  • Patent number: RE43674
    Abstract: A new post-passivation metal interconnect scheme is provided over the surface of a IC device that has been covered with a conventional layer of passivation. The metal scheme of the invention comprises, overlying a conventional layer of passivation, thick and wide metal lines in combination with thick layers of dielectric and bond pads. The interconnect system of the invention can be used for the distribution of power, ground, signal and clock lines from bond pads to circuits of a device that are provided in any location of the IC device without introducing significant power drop. No, or smaller ESD circuits are required due to the low impedance post-passivation interconnection, since any accumulated electrostatic discharge will be evenly distributed across all junction capacitance of the circuits on the chip. The post passivation metal scheme is connected to external circuits through bond pads, solder bonding, TAB bonding and the like.
