The ashing rate is related to the power used during processing. Higher power gives higher ashing rate. | The ashing rate is related to the power used during processing. Higher power gives higher ashing rate. | ||
Test using a single 100 mm wafer in the center of the process chamber shows that a power of 1000 W gives the highest ashing rate. | Test using a single 100 mm wafer in the center of the process chamber shows that a power of 1000 W gives the highest ashing rate. | ||
