    Abstract: Embodiments described herein provide a gas supply system for reducing purge time and increasing processing throughput, and an atomic layer deposition (ALD) chamber having the same. The gas supply system includes an inert gas line and a precursor supply line. The inert gas line is configured to be coupled to an inlet of the chamber separate from the precursor supply line. Therefore, the inert gas is supplied concurrently to the precursor supply line and the processing region of the chamber such that total purge time is reduced. The reduction of the total purge time due to the gas supply system increases purge efficiency and increases processing throughput. Furthermore, the gas supply system allows inert gas to be utilized as a dilution gas during flow of precursors.

    Abstract: Embodiments described herein provide a chamber having a gas flow inlet guide to uniformly deliver process gas and a gas flow outlet guide to effectively purge process gasses and reduce purge time. The chamber includes a chamber body having a process gas inlet and a process gas outlet, a lid assembly, a process gas inlet and a process gas outlet configured to be in fluid communication with a processing region in the chamber, a gas flow inlet guide disposed in the process gas inlet, and a gas flow outlet guide disposed in the process gas outlet. The gas flow inlet guide includes a flow modulator and at least two first inlet guide channels having first inlet guide channel areas that are different. The gas flow outlet guide includes at least two first outlet guide channels having first outlet guide channel areas that are different.

    Abstract: Embodiments described herein generally relate to a method and apparatus for encapsulating an OLED structure, more particularly, to a TFE structure for an OLED structure. The TFE structure includes at least one dielectric layer and at least two barrier layers, and the TFE structure is formed over the OLED structure. The at least one dielectric layer is deposited by atomic layer deposition (ALD). Having the at least one dielectric layer formed by ALD in the TFE structure improves the barrier performance of the TFE structure.
