As a senior process engineer, my daily duties are sustaining current process, maintaining the SPC charts on most of the etch tools plus checking utilization and up-time of our tools.
The hardest part of the job is to deal with multiple tasks at once where you disposition products and also some quals failed on which you need to determine the root cause plus making a decision on what needs to be done with the tool. Do we need more troubleshooting? or Do I have to involve maintenance to look into gas flow issues for example?. At the same time the line is stopped due to the failed qual, meaning the tool availability is in question. At the same time automation issue where some products are fully processed but the system didn't recognize if they were done. In that case we need to verify through the system if the product was either fully processed or was not processed.
