LARGE-AREA HIGH-DENSITY PLASMA PROCESSING CHAMBER FOR FLAT PANEL DISPLAYS

Embodiments described herein provide a lid assembly of a chamber for independent control of plasma density and gas distribution within the interior volume of the chamber. The lid assembly includes a plasma generation system and a gas distribution assembly. The plasma generation system includes a plurality of dielectric plates having a bottom surface oriented with respect to vacuum pressure and a top surface operable to be oriented with respect to atmospheric pressure. One or more coils are positioned on or over the plurality of dielectric plates. The gas distribution assembly includes a first diffuser and a second diffuser. The first diffuser includes a plurality of first channels intersecting a plurality of second channels of the second diffuser. 本文描述的实施方式提供一种用于独立地控制在腔室的内部容积内的等离子体密度和气体分配的腔室的盖组件。所述盖组件包括等离子体生成系统和气体分配组件。所述等离子体生成系统包括多个介电板，所述介电板具有相对于真空压力取向的底表面和可操作以相对于大气压力取向的顶表面。一个或多个线圈定位在所述多个介电板上或上方。所述气体分配组件包括第一扩散器和第二扩散器。所述第一扩散器包括与所述第二扩散器的多个第二通道相交的多个第一通道。
