Latest Patents
Puthur Paulson holds a patent titled "High rate sputter deposition of alkali metal-containing precursor films useful to fabricate chalcogenide semiconductors." This invention provides methods to sputter deposit films comprising alkali metal compounds. The process involves sputtering at least one target that includes one or more alkali metal compounds and at least one metallic component to form corresponding sputtered films. The atomic ratio of the alkali metal compound to the metallic component in the target ranges from 15:85 to 85:15. The resulting sputtered films, which incorporate alkali metal compounds, are integrated into a precursor structure that also includes chalcogenide precursor films. This precursor structure is then heated in the presence of at least one chalcogen to produce a chalcogenide semiconductor. The final semiconductor can contain up to 2 atomic percent of alkali metal content, primarily derived from the sputtered films. These chalcogenide semiconductors are particularly useful in microelectronic devices, including solar cells.
