METHODS AND APPARATUS FOR DEPOSITING CHALCOGENIDE LAYERS USING HOT WIRE CHEMICAL VAPOR DEPOSITION

摘要

Methods and apparatus for depositing chalcogenide materials on substrates in a hot wire chemical vapor deposition (HWCVD) process are provided herein. In some embodiments, a method of depositing a chalcogenide film atop a substrate in a hot wire chemical vapor deposition (HWCVD) process chamber includes vaporizing one or more liquid chalcogenide precursors while flowing a carrier gas to form a first gas mixture of the vaporized chalcogenide precursor and the carrier gas; mixing the first gas mixture with a second gas to form a second gas mixture, wherein the second gas is a catalyst; and flowing the second gas mixture to the HWCVD process chamber, wherein the second gas mixture dissociates in the HWCVD process chamber to deposit a chalcogenide film atop the substrate.
