  • Patent number: 8426971
    Abstract: A titanium-nickel-palladium solderable metal system for silicon power semiconductor devices (10), which may be used for one or both of the anode (20) or cathode (30). The metal system includes an outer layer of palladium (40,70), an intermediate layer of nickel (50,80), and an inner layer of titanium (60,90). For certain applications, the nickel may be alloyed with vanadium. The metal system may be deposited on bare silicon (100) or on one or more additional layers of metal (110) which may include aluminum, aluminum having approximately 1% silicon, or metal silicide. The use of palladium, rather than gold or silver, reduces cost, corrosion, and scratching.

  • Patent number: 8390134
    Abstract: To provide: a technique capable of suppressing a titanium nitride film that is exposed at the side surface of an opening from turning into a titanium oxide film even when water permeates the opening over a pad from outside a semiconductor device and thus improving the reliability of the semiconductor device; and a technique capable of suppressing a crack from occurring in a surface protective film of a pad and improving the reliability of a semiconductor device. An opening is formed so that the diameter of the opening is smaller than the diameter of another opening and the opening is included in the other opening. Due to this, it is possible to cover the side surface of an antireflection film that is exposed at the side surface of the other opening with a surface protective film in which the opening is formed. As a result of this, it is possible to form a pad without exposing the side surface of the antireflection film.

    Abstract: Disclosed is a metal structure of a multi-layer substrate, comprising a first metal layer and a dielectric layer. The first metal layer has an embedded base and a main body positioned on the embedded base. The base area of the embedded base is larger than the base area of the main body. After the dielectric layer covers the main body and the embedded base, the dielectric layer is opened at the specific position of the first metal layer for connecting the first metal layer with a second metal layer above the dielectric layer. When the metal structure is employed as a pad or a metal line of the flexible multi-layer substrate according to the present invention, the metal structure cannot easily be delaminated or separated from the contacted dielectric layer. Therefore, a higher reliability for the flexible multi-layer substrate can be achieved.

  • Patent number: 7911060
    Abstract: A multilayer wiring structure of a semiconductor device having a stacked structure is arranged to restrain reliability degradation due to stress applied to the region of wiring between opposite upper and lower plugs. The rate of overlap of contact surface between upper plug and wiring on contact surface between lower plug and wiring, is small to the extent that no void is generated. The multilayer wiring structure is produced such that no grain boundary is contained in the region of wiring between upper and lower plugs. The difference in thermal expansion coefficient between the material of wiring and the material of upper and lower plugs, is small to the extent that no void is generated.

  • Patent number: RE41980
    Abstract: A plurality of metal wires are formed on an underlying interlayer insulating film. Areas among the metal wires are filled with a buried insulating film of a silicon oxide film with a small dielectric constant (i.e., a first dielectric film), and thus, a parasitic capacitance of the metal wires can be decreased. On the buried insulating film, a passivation film of a silicon nitride film with high moisture absorption resistance (i.e., a second dielectric film) is formed, and thus, a coverage defect can be avoided. A bonding pad is buried in an opening formed in a part of a surface protecting film including the buried insulating film and the passivation film, so as not to expose the buried insulating film within the opening. Thus, moisture absorption through the opening can be prevented.
