  • Publication number: 20120104619
    Abstract: A first low dielectric constant (low-k) dielectric material layer is lithographically patterned to form a recessed region having expose substantially vertical sidewalls, which are subsequently damaged to de-carbonize a surface portion at the sidewalls having a sublithographic width. A second low-k dielectric material layer is deposited to fill the recessed region and planarized to exposed top surfaces of the damaged low-k dielectric material portion. The damaged low-k dielectric material portion is removed selective to the first and second low-k dielectric material layers to form a trench with a sublithographic width. A portion of the pattern of the sublithographic-width trench is transferred into a metallic layer and optionally to an underlying dielectric masking material layer to define a trench with a sublithographic width, which can be employed as a template to confine the widths of via holes and line trenches to be subsequently formed in an interconnect-level dielectric material layer.

    Abstract: According to certain embodiments, Ru is removed from the surface of a semiconductor structure by contact with a cleaning solution comprising one or more selected from permanganate ion, orthoperiodic ion and hypochlorous ion, such that Ru is removed from surfaces of the semiconductor substrate where the presence of Ru is undesirable. In some embodiments, a semiconductor structure is formed or provided having at least one metalized layer formed over an underlying layering or semiconductor substrate. The metalized layer contains a dielectric material with one or more metal wires of copper-containing material formed in a trench and/or via in the dielectric material. A cap layer having Ru is formed on the surface of the copper-containing material forming the one or more metal wires. The semiconductor structure is contacted with the cleaning solution comprising one or more selected from permanganate ion, orthoperiodic ion and hypochlorous ion to remove a portion of the Ru present in the semiconductor structure.

  • Patent number: 8120167
    Abstract: A method for fabricating a semiconductor component with an encapsulated through wire interconnect includes the steps of providing a substrate having a first side, a second side and a substrate contact; forming a via in the substrate contact and the substrate to the second side; placing a wire in the via; forming a first contact on the wire proximate to the first side and a second contact on the wire proximate to the second side; and forming a polymer layer on the first side leaving the first contact exposed. The polymer layer can be formed using a film assisted molding process including the steps of: forming a mold film on tip portions of the bonding members, molding the polymer layer, and then removing the mold film to expose the tip portions of the bonding members. The through wire interconnect provides a multi level interconnect having contacts on opposing sides of the semiconductor substrate.

  • Patent number: 8120159
    Abstract: A step of forming a through hole in a semiconductor substrate, or a step of polishing the semiconductor substrate from its back surface requires a very long time and causes decrease of productivity. In addition, when semiconductor substrates are stacked, a semiconductor integrated circuit which is formed of the stack is thick and has poor mechanical flexibility. A release layer is formed over each of a plurality of substrates, layers each having a semiconductor element and an opening for forming a through wiring are formed over each of the release layers. Then, layers each having the semiconductor element are peeled off from the substrates, and then overlapped and stacked, a conductive layer is formed in the opening, and the through wiring is formed; thus, a semiconductor integrated circuit is formed.

  • Publication number: 20120038054
    Abstract: A method of improving electrical interconnections between two electrical elements is made available by providing a meta-material overlay in conjunction with the electrical interconnection. The meta-material overlay is designed to make the electrical signal propagating via the electrical interconnection to act as though the permittivity and permeability of the dielectric medium within which the electrical interconnection is formed are different than the real component permittivity and permeability of the dielectric medium surrounding the electrical interconnection. In some instances the permittivity and permeability resulting from the meta-material cause the signal to propagate as if the permittivity and permeability have negative values. Accordingly the method provides for electrical interconnections possessing enhanced control and stability of impedance, reduced noise, and reduced loss.

An integrated circuit attached to a surface of the substrate is electrically connected to the wire layout pattern. An encapsulation material covers at least the integrated circuit and the solder mask layer. One or more crack seal rings are disposed on the solder mask surface. The crack seal rings are copper traces with terminals that allow current to be applied to the traces. A broken trace (open circuit condition) is indicative of a crack in the package. Thus, electrical testing is performed to detect physical defects.
