Abstract: A chamber body includes a ceramic weldment having a lower wall, a sidewall, and an upper wall. The sidewall is coupled to the lower wall by a sidewall-to-lower wall weld and the upper wall is coupled to the sidewall by a sidewall-to-upper wall weld. The upper wall has an upper wall plate portion and an upper wall rib portion extending therefrom formed from a singular quartz workpiece using a subtractive manufacturing technique, the upper wall further having a unwelded ribbed region overlying the lower wall. Chamber arrangements, semiconductor processing systems and related methods of making chamber bodies and depositing material layers onto substrates supported within chamber bodies are also described.
