Abstract:
In a solid precursor evaporation system (50, 150, 300, 300') configured for use in a thin film deposition system (1, 100), such as thermal chemical vapor deposition (TCVD), a method for preparing one or more trays (330, 340) of solid precursor is described. The solid precursor may be formed on a coating substrate, such as a tray (330, 340), using one or more of dipping techniques, spin-on techniques, and sintering techniques.
Abstract:
A replaceable precursor tray for use with a high conductance, multi-tray solid precursor evaporation system (50, 150, 300, 300') 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 (50, 150, 300, 300') is configured to be coupled to the process chamber (10, 110) of a thin film deposition system (1, 100), and it includes a base tray (330) with one or more stackable upper trays (340). Each tray (330, 340) is configured to support and retain film precursor (350) in, for example, solid powder form or solid tablet form. Additionally, each tray (330, 340) is configured to provide for a high conductance flow of carrier gas over the film precursor (350) while the film precursor (350) is heated. For example, the carrier gas flows inward over the film precursor (350), and vertically upward through a flow channel (318) within the stackable trays (370, 370') and through an outlet (322) in the solid precursor evaporation system (50, 150, 300, 300').
Abstract:
A method for depositing Ru and Re metal layers on substrates with high deposition rates, low particulate contamination, and good step coverage on patterned substrates is presented. The method includes providing a substrate in a process chamber, introducing a process gas in the process chamber in which the process gas comprises a carrier gas and a metal precursor selected from the group consisting of a ruthenium-carbonyl precursor and a rhenium-carbonyl precursor. The method further includes depositing a Ru or Re metal layer on the substrate by a thermal chemical vapor deposition process at a process chamber pressure less than about 20 mTorr.
