摘要： Embodiments of the present invention generally relate to a gas distribution showerhead having insulated corner regions to reduce arcing and improve deposition uniformity control. In one embodiment, the gas distribution showerhead is formed of a conductive material with material from the corner regions removed. Corner members formed substantially in the shape of the removed portion of corner regions are attached to the conductive showerhead. The corner members may be made of a material having electrical insulating properties, such as a ceramic or insulating polymer.

摘要： Embodiments disclosed herein generally relate to an apparatus having an anodized gas distribution showerhead. In large area, parallel plate RF processing chambers, mastering the RF return path can be challenging. Arcing is a frequent problem encountered in RF processing chambers. To reduce arcing in RF processing chambers, straps may be coupled to the susceptor to shorten the RF return path, a ceramic or insulating or anodized shadow frame may be coupled to the susceptor during processing, and an anodized coating may be deposited onto the edge of the showerhead that is nearest the chamber walls. The anodized coating may reduce arcing between the showerhead and the chamber walls and therefore enhance film properties and increase deposition rate.
摘要翻译：本文公开的实施方案通常涉及具有阳极氧化气体分配喷头的装置。在大面积的平行板RF处理室中，掌握RF返回路径可能具有挑战性。射频是RF处理室遇到的一个常见问题。为了减少RF处理室中的电弧，带可以耦合到基座以缩短RF返回路径，陶瓷或绝缘或阳极氧化的阴影框架可以在处理期间耦合到基座，并且阳极化涂层可以沉积在最靠近室壁的淋浴头。阳极化涂层可以减少喷头和室壁之间的电弧，并因此增强膜的性质并增加沉积速率。

摘要： The present invention generally includes a plasma enhanced chemical vapor deposition (PECVD) processing chamber having an RF power source coupled to the backing plate at a location separate from the gas source. By feeding the gas into the processing chamber at a location separate from the RF power, parasitic plasma formation in the gas tubes leading to the processing chamber may be reduced. The gas may be fed to the chamber at a plurality of locations. At each location, the gas may be fed to the processing chamber from the gas source by passing through a remote plasma source as well as an RF choke or RF resistor.

摘要： Embodiments of a gas diffuser plate for distributing gas in a processing chamber are provided. The gas distribution plate includes a diffuser plate having an upstream side and a downstream side, and a plurality of gas passages passing between the upstream and downstream sides of the diffuser plate. The gas passages include hollow cathode cavities at the downstream side to enhance plasma ionization. The depths, the diameters, the surface area and density of hollow cathode cavities of the gas passages that extend to the downstream end can be gradually increased from the center to the edge of the diffuser plate to improve the film thickness and property uniformity across the substrate. The increasing diameters, depths and surface areas from the center to the edge of the diffuser plate can be created by bending the diffuser plate toward downstream side, followed by machining out the convex downstream side. Bending the diffuser plate can be accomplished by a thermal process or a vacuum process. The increasing diameters, depths and surface areas from the center to the edge of the diffuser plate can also be created computer numerically controlled machining. Diffuser plates with gradually increasing diameters, depths and surface areas of the hollow cathode cavities from the center to the edge of the diffuser plate have been shown to produce improved uniformities of film thickness and film properties.
摘要翻译：提供了用于在处理室中分配气体的气体扩散板的实施例。气体分配板包括具有上游侧和下游侧的扩散板，以及在扩散板的上游侧和下游侧之间通过的多个气体通路。气体通道包括在下游侧的中空阴极腔，以增强等离子体电离。延伸到下游端的气体通道的空心阴极腔的深度，直径，表面积和密度可以从扩散板的中心到边缘逐渐增加，以改善衬底上的膜厚度和性能均匀性。从扩散板的中心到边缘的直径，深度和表面积的增加可以通过向下游侧弯曲扩散板，然后在凸出的下游侧加工出来。扩散板的弯曲可以通过热处理或真空工艺来实现。从扩散板的中心到边缘的直径，深度和表面积的增加也可以用计算机数字控制加工。具有从扩散板的中心到边缘的中空阴极腔的直径逐渐增加，深度和表面积逐渐增大的扩散板已被证明可以产生改善的膜厚度和膜性质的均匀性。
