Process Engineering

Our Process Engineers analyze and evaluate the efficiency, quality and safety of our products. Our colleague Andrea from Dresden explains what makes this job so exciting.

"I detect possible contaminations and optimize the production process." Andrea Landgraf, Process Engineer
"What you see on my monitor? The red-colored areas suggest metal contamination. In this case, one of our process cells was showing iron."

Overview: Tasks & Requirements

As a Process Engineer, you will test and optimize the production processes in different manufacturing environments. The goal of your job is to analyze and evaluate the efficiency, quality and safety of our products. You will use the results of your analyses to make founded recommendations to the product team – for example, on relevant process modifications, material changes, or the replacement of tools.

Your tasks consist of:

  • Responsibility for the processes in your area
  • Working on further development of procedures and processes
  • Implementing manufacturing specifications and quality-related process parameters

You have the following skills:

  • College degree in a scientific field
  • You know how to generate value from ideas and solutions, and are open to new approaches
  • Fluent in German and English

Andrea Landgraf, Process Engineer in Dresden

I am in charge of the wet-chemical processes in Infineon’s chip production. These are typically used in the production of low particle surfaces using special cleanings, the production of structures by etching of masked layers and in removing resist layers from photo-lithographic processes. In addition to the new development and optimization of existing processes, I also look into deviations: for example, if too many particles are on the silicon wafer.

I run much of this work from my computer, such as setting and evaluation of parameters of the etching and cleaning equipment. Of course, I also go into the clean room to the facilities and chemical baths to see that everything is running smoothly - of course I take off my make-up beforehand, because of the particles ;-).

Very often I run tests on the equipment in order either to resolve problems or to find an optimum solution.

In addition to daily operational work, I’m also involved in projects. A current example is the development of decision-making support for the procedure after wafer breakage: How to deal with the remaining wafers from the lot, and how can we improve the monitoring mechanisms?

As a Process Engineer, I have to work reliably under pressure and need a certain resilience, since we often have to deal with many issues simultaneously. The stability of the production process always has priority - meaning that I have to respond flexibly and quickly right away when the first signs of instability occur.

Since I work with colleagues from many different fields and different prior knowledge, it is essential to be happy to communicate and to do it well. It is also important to be able to set priorities and you should have to have a certain degree of tenacity to be able to get them implemented.

And as I work in the field of wet chemistry, I need of course a background in chemistry.

I’ve been working in this field for ten years and it has never been boring. Since, on the one hand, there are always new technologies that have to be developed for the customized wet chemical processes, and on the other, there are always new problems that need to be addressed. Troubleshooting is almost like detective work. It's fun to find out the causes and to work on improvements - particularly in collaboration with experts from other fields. I can work very independently and flexibly make my own work hours to some extent. I really appreciate that!

I feel Infineon is very family friendly and I like going to the parties they organize here, together with my husband and my kid.

What are my lowlights? Some problems, particularly in the context of particle contamination, prove to be very persistent, and the path to solving them is often tedious and leads to lots of failed attempts before you succeed.  

When I was a kid I wanted to be a teacher, then I considered studying medicine. Ultimately I wound up studying Chemistry. After my PhD at the University of Leipzig, I came to Infineon in Dresden and I have worked here for ten years.
