Abstract
A processing chamber component and method for fabricating the same are provided. The processing chamber component is fabricated in the manner described herein and includes the creation of at least a macro texture on a surface of the chamber component. The macro texture is defined by a plurality of engineered features arranged in a predefined orientation on the surface of the chamber component. In some embodiments, the engineered features prevent formation of a line of sight surface defined between the features to enhance retention of films deposited on the chamber component.
