  • Patent number: 8962482
    Abstract: An integrated circuit interconnect is fabricated by using a mask to form a via in an insulating layer for a conductive plug. After the plug is formed in the via, a thin (e.g., <100 nm) isolation layer is deposited over the resulting structure. An opening is created in the isolation layer by using the same mask at a different radiation exposure level to make the opening more narrow than the underlying plug. A conductive line is then formed which makes electrical contact with the plug through the opening in the isolation layer. By vertically separating and electrically isolating the conductive plug from adjacent conductive lines, the isolation layer advantageously reduces the likelihood of an undesired electrical short occurring between the conductive plug and a nearby conductive line.

  • Patent number: 8951906
    Abstract: A method for fabricating through-silicon vias (TSVs) for semiconductor devices is provided. Specifically, the method involves utilizing copper contact pads in a back-end-of-line wiring level, wherein the copper contact pads act as cathodes for performing an electroplating technique to fill TSVs with plated-conductive material (e.g., copper) from an electroplating solution. Moreover, the method provides a way to fill high aspect ratio TSVs with minimal additional semiconductor fabrication process steps, which can increase the silicon area that is available for forming additional electronic components on integrated circuits.

  • Publication number: 20150037972
    Abstract: Described are cleaning methods for removing contaminants from an electrical contact interface of a partially fabricated semiconductor substrate. The methods may include introducing a halogen-containing species into a processing chamber, and forming an adsorption-limited layer, which includes halogen from the halogen-containing species, atop the electrical contact interface and/or the contaminants thereon. The methods may further include thereafter removing un-adsorbed halogen-containing species from the processing chamber and activating a reaction between the halogen of the adsorption-limited layer and the contaminants present on the electrical contact interface. The reaction may then result in the removal of at least a portion of the contaminants from the electrical contact interface. In some embodiments, the halogen adsorbed onto the surface and reacted may be fluorine. Also described herein are apparatuses having controllers for implementing such electrical contact interface cleaning techniques.

  • Patent number: 8940631
    Abstract: Methods of forming coaxial feedthroughs for 3d integrated circuits that provide excellent isolation of signal paths from the substrate and from adjacent feedthroughs. One method is to form a recess in a substrate and deposit alternate layers of insulation and conductive layers and then thin the substrate to make the layers available from both sides of the substrate, with the first metal layer forming the coaxial conductor and the second metal layer forming the central conductor. Alternatively the coaxial feedthroughs may be formed using a modified pillar process to form the coaxial conductor at the same time as the center conductor is formed so that the coaxial feedthrough is formed without requiring extra steps. Both processes are low temperature processes.

  • Patent number: 8936960
    Abstract: A method for fabricating an integrated device includes the following steps. First, a multi-layered structure is formed on a substrate, wherein the multi-layered structure is embedded in a lower isolation layer. Then, a bottom conductive pattern and a top conductive pattern are formed on a top surface of the lower isolation layer, wherein the top conductive pattern is on a top surface of the bottom conductive pattern. Afterwards, portions of the top conductive pattern are removed to expose portions of the bottom conductive pattern. Subsequently, an upper isolation layer is deposited on the lower isolation layer so that the upper isolation layer can be in direct contact with the portions of the bottom conductive pattern. Finally, portions of the lower isolation layer and the upper isolation layer are removed so as to expose portions of the substrate.

  • Patent number: 8937009
    Abstract: Disclosed are a method for metallization during semiconductor wafer processing and the resulting structures. In this method, a passivation layer is patterned with first openings aligned above and extending vertically to metal structures below. A mask layer is formed and patterned with second openings aligned above the first openings, thereby forming two-tier openings extending vertically through the mask layer and passivation layer to the metal structures below. An electrodeposition process forms, in the two-tier openings, both under-bump pad(s) and additional metal feature(s), which are different from the under-bump pad(s) (e.g., a wirebond pad; a final vertical section of a crackstop structure; and/or a probe pad). Each under-bump pad and additional metal feature initially comprises copper with metal cap layers thereon.
