| description | A system and method of applying power to a target plasma chamber include, characterizing a no plasma performance slope of the target plasma chamber, applying a selected plasma recipe to a first wafer in the target chamber, the selected plasma recipe includes a selected power set point value and monitoring a recipe factor value on the RF electrode. A ratio of process efficiency is generated comparing the reference chamber and the target chamber, the generating using as inputs the no plasma performance slopes of the target chamber and the reference chamber and the monitored recipe factor value. An adjusted power set point value is calculated, the adjusted power set point configured to cause power delivered to a plasma formed in the target chamber to match power that would be delivered to a reference plasma formed in the reference chamber. |
