Abstract
An electrode pattern and layered assembly is disclosed. This assembly utilizes multiple-piece construction, including at least two electrically conductive layers and at least three electrically insulating layers. By incorporating a second electrically conductive layer, each electrode can be divided into two or more separate portions on the top layer, and joined together using the second conductive layer. Connections between the two conductive layers can be made using any suitable technique, including through-hole vias, conductive rods and the like. The use of a second electrically conductive layer also allows for a different gas distribution strategy. The use of multiple conductive layers allows the use of one or more concentric channels to be used through which the gas can be injected.
