Process engineers maintain processes running. Some day-in-day-out tasks include:
- monitoring control charts to make sure the process is running within control limits
- working with other engineers, such as yield engineers, quality engineers, other processes engineers to improve the process throughput (making more product in less time) and quality
- work with maintenance engineers (the guys that fix the hardware of the tools when they break) to troubleshoot tool issues when the process is out of control
- work with maintenance engineers and vendors to evaluate new parts to make a process better
- process/tool evaluations to compare current a process/tool to a new process(es)/tool(s); comparison will include evaluation of process parameters (such as film removal rate) and cost
I'm in the semiconductor field; here's a list of some of the lingo we used, that may be used across other process engineering fields:
- SPC (Statistical Process Control): the process is monitored using tests; the data is entered into some software and is plotted over time
- FMEA (Failure Mode Effect Analysis): basically an excel spreadsheet that documents what could go wrong with a process
- Lean Manufacturing: making more and better product with less cost
- Spec's: not the liquor store... Spec's = Specifications = a word document that details how to run a process on a tool, how to qualify it; lists the chemicals used
Most of the process engineers I work with are ChemE's, EE's, Chemistry majors, Material Science majors
