  • Publication number: 20230253361
    Abstract: Technologies for plasma oxidation protection during hybrid bonding of semiconductor devices includes forming a blocking layer on a metallic bonding pad formed in a bonding surface of a semiconductor device to be bonded and performing a surface treatment on the bonding surface to increase the bonding strength of the bonding surface and contemporaneously remove the blocking layer from the metallic bonding pad. In an illustrative embodiment, the blocking layer is embodied as a self-assembled monolayer (SAM), and the surface treatment is embodied as a surface activation plasma (SAP) treatment. A diffusion barrier layer, such as a silicon carbon nitride layer, may form the bonding surface in some embodiments to reduce diffusion of the metallic bonding pad during an annealing treatment of the bonding process.

  • Patent number: 9370875
    Abstract: An imprinting method is capable of separating a molding material and a target material rapidly in pattern formation. The imprinting method includes a transferring process for transferring an inverted pattern of a mold 10 having a desired pattern formed thereon to a resist 30 by pressing the mold 10 against the resist 30; a curing process for curing the resist 30 by heating or irradiating light; and a separating process for separating the mold 10 from the resist 30 after the resist 30 is cured through the transferring process. The separating process includes a pulling process for pulling the mold 10 away from the resist 30 in a direction opposite to a direction in which the resist 30 is pressed; and a pushing process for pushing the resist 30 in the same direction as a direction in which the mold 10 presses the resist 30.

  • Patent number: 8940638
    Abstract: In a substrate wiring method, copper is embedded all the way to the lowest parts of a wiring pattern formed on a substrate. The method is used to wire a substrate in a processing chamber kept in a vacuum state, the substrate having a wiring pattern formed thereon. The method includes a preprocessing step in which the wiring pattern on the substrate is cleaned using a desired cleaning gas and an embedding step in which, after the preprocessing step, metal nanoparticles are embedded in the wiring pattern using a clustered metal gas.

  • Publication number: 20130056024
    Abstract: A substrate cleaning method for cleaning a substrate on which a film is formed with a pattern in a vacuum-state processing chamber includes a preprocessing step where the film formed on the substrate on which the pattern has been formed by an etching process is cleaned by using a cleaning gas; and a consecutive step including an oxidation step where residues attached on a surface of the pattern are oxidized by using an oxidizing gas and a reduction step where the oxidized residues are reduced by using a reducing gas, which are consecutively carried out posterior to the preprocessing step. The gases used in the preprocessing step and the consecutive step are clustered by ejecting the gases into the processing chamber from a gas nozzle whose internal pressure PS is maintained to be higher than an internal pressure PO of the processing chamber.

    Abstract: An interconnect structure for an integrated circuit and method of forming the interconnect structure. The method includes depositing a metallic layer containing a reactive metal in an interconnect opening formed within a dielectric material containing a dielectric reactant element, thermally reacting at least a portion of the metallic layer with at least a portion of the dielectric material to form a diffusion barrier primarily containing a compound of the reactive metal from the metallic layer and the dielectric reactant element from the dielectric material, and filling the interconnect opening with Cu metal, where the diffusion barrier surrounds the Cu metal within the opening. The reactive metal can be Co, Ru, Mo, W, or Ir, or a combination thereof. The interconnect opening can be a trench, a via, or a dual damascene opening.

  • Publication number: 20120071003
    Abstract: Disclosed is a technology in which a nozzle part is mounted in a vacuum chamber and a silicon substrate is held to face a discharge hole of the nozzle part. For example, ClF3 gas and Ar gas are supplied from the nozzle part and the mixed gas is discharged from the nozzle part under a vacuum atmosphere. By doing this, the mixed gas is adiabatically expanded and the Ar atoms or ClF3 molecules are combined, which become a gas cluster. The gas cluster is irradiated to the surface of the silicon substrate without being ionized and, as a result, the surface of the silicon surface becomes a porous state. Then, lithium is grown on the surface of the silicon substrate in a separate vacuum chamber 41 by sputtering without breaking the vacuum.

  • Publication number: 20100132613
    Abstract: The present invention relates to a method of lowering dielectric constant of an insulating film including Si, O and CH formed by a chemical vapor deposition process. A process gas containing hydrogen atoms is supplied into a reaction vessel. A microwave is introduced into the reaction vessel to supply a uniform electromagnetic wave, thereby a plasma containing a hydrogen radical is generated in the reaction vessel. The structure of the insulating film is modified by the hydrogen radical contained in the plasma irradiated to the insulating film, lowering the dielectric constant of the film. The microwave is supplied into the reaction vessel through a radial-slot antenna.
