The ashing rate is related to the gas mix, usually expressed as percentage of nitrogen of the total amount of gas. | The ashing rate is related to the gas mix, usually expressed as percentage of nitrogen of the total amount of gas. | ||
Testing found that a gas mix of 50% nitrogen gives the highest ashing rate for both processing single substrates and when processing a full boat with 25 substrates. | Testing found that a gas mix of 50% nitrogen gives the highest ashing rate for both processing single substrates and when processing a full boat with 25 substrates. Please note that the ashing rate for a full boat is approximately ten times slower, than when processing a single substrate. | ||
