摘要:
A method for improving adhesion of Cu to a Ru layer in Cu metallization. The method includes providing a substrate in a process chamber of a deposition system, depositing a Ru layer on the substrate in a chemical vapor deposition process, and forming a Cu seed layer on the Ru layer to prevent oxidation of the Ru layer. The Cu seed layer is partially or completely oxidized prior to performing a Cu bulk plating process on the substrate. The oxidized portion of the Cu seed layer is substantially dissolved and removed from the substrate during interaction with a Cu plating solution, thereby forming a bulk Cu layer with good adhesion to the underlying Ru layer.

A high conductance, multi-tray film precursor evaporation system coupled with a high conductance vapor delivery system is described for increasing the deposition rate by increasing exposed surface area of film precursor. The multi-tray film precursor evaporation system includes one or more trays. Each tray is configured to support and retain film precursor in, for example, solid powder form or solid tablet form. Additionally, each tray is configured to provide for a high conductance flow of carrier gas over the film precursor while the film precursor is heated. For example, the carrier gas flows inward over the film precursor, and vertically upward through a flow channel within the stackable trays and through an outlet in the solid precursor evaporation system.
摘要:
A method and system for improved delivery of a solid precursor. A chemically inert coating is provided on system components in a precursor delivery line to reduce decomposition of a relatively unstable precursor vapor in the precursor delivery line, thereby allowing increased delivery of the precursor vapor to a processing zone for depositing a layer on a substrate. The solid precursor can, for example, be a ruthenium carbonyl or a rhenium carbonyl. The inert coating can, for example, be a CxFy-containing polymer, such as polytetrafluoroethylene or ethylene-chlorotrifluoroethylene. Other benefits of using an inert coating include easy periodic cleaning of deposits from the precursor delivery line.

A high conductance, multi-tray solid precursor evaporation system coupled with a high conductance vapor delivery system is described for increasing deposition rate by increasing exposed surface area of solid precursor. The multi-tray solid precursor evaporation system includes a base tray with one or more upper trays. Each tray is configured to support and retain film precursor in, for example, solid powder form or solid tablet form. Additionally, each tray is configured to provide for a high conductance flow of carrier gas over the film precursor while the film precursor is heated. For example, the carrier gas flows inward over the film precursor, and vertically upward through a flow channel within the stackable trays and through an outlet in the solid precursor evaporation system.

To provide an optical waveguide and an optical transmitting and receiving module able to perform a transmitting operation and a receiving operation simultaneously, wherein a linearly first waveguide 21 that one side is coupled to an optical fiber 3 and the other side is coupled to a light receiving element 4, and a second waveguide 22 that one side is coupled so as to make an acute angle θ with the side of the first waveguide 21 to be coupled to the light receiving element 4 and the other is coupled to a light emitting element 5 are provided. By controlling a shape of the second waveguide 22, the receiving signal light from the optical fiber 3 is received to the light receiving element 4, and is not guided to the second waveguide 22. Therefore, the receiving operation and the transmitting operation can be preformed at the same time. Namely, when the transmitting optical signal is the incident of light from the light emitting element 5 to the second waveguide 22, the optical signal is guided by the second waveguide 22 toward the first waveguide 21, coupled to the first waveguide 21, and guided toward the optical fiber 3.

A nanometer size roughened structure is formed on a surface of a light-emitting element, and luminous efficiency is improved. The roughened structure on the surface of the light-emitting element of the invention is formed into the following shape such that the refractive index smoothly changes: (1) the mean diameter of projections on the roughened surface is smaller than the light wavelength; (2) a pitch of the roughened surface is irregular; and (3) positions of the top and bottom of the roughened surface are distributed from their mean values within the light wavelength in order to give a smooth gradient of the refractive index. The surface of such light-emitting element is obtained by forming a thin film on the surface of the light-emitting element using a resin composition which contains a block copolymer or graft copolymer and forms a micophase-separated structure in a self-organization manner; selectively removing at least one phase of the microphase-separated structure of the thin film formed on the surface; and etching the surface of the light-emitting element using the remaining phase as an etching mask.
