Process Development Engineer Fahimeh Emadi drives silicon MEMS resonators from wafer to packaging

Meet our team! Fahimeh Emadi is a Process Development Engineer responsible for our silicon MEMS resonators, overseeing them from the raw wafer stage through to final packaging. Find out more about Fahimeh’s work!

From materials science research to working as a Process Development Engineer

The development of silicon MEMS resonators requires technical expertise, continuous experimentation, and close collaboration across engineering disciplines. Fahimeh Emadi is one part of that process, as she works as a Process Development Engineer. She is responsible for the production, development, and process improvement of our silicon MEMS resonators.

Fahimeh joined Kyocera Technologies in 2024, just as she was finishing her PhD at Aalto University. She is originally from Iran, where she completed her Bachelor’s and Master’s degrees. She moved to Finland at the end of 2019 to focus on more research-oriented work. Her background is in material science, as she wrote her PhD thesis in electronics integration and reliability.

“When I was looking for my next step after my PhD, I wanted to find a company where I could work closely with MEMS devices and packaging. Kyocera was my first choice, and I was fortunate that a process engineering position opened up at just the right time”, Fahimeh says.

At Kyocera Technologies, structured, hands-on execution meets creative R&D

As a Process Development Engineer, Fahimeh’s daily work centers on the fabrication of resonators and continuous process improvement. Her responsibilities cover the entire manufacturing flow, meaning she maintains a highly hands-on role in the cleanroom.

“In general, a Process Engineer here has a wide variety of tasks. It is all about the performance and physical fabrication of our resonators,” she explains. “When we have fabrication runs, I am responsible for planning them, defining the process flows, creating the run sheets, and executing the fabrication itself. This work goes all the way from the raw wafer level to the final packaging stage.”

In the world of silicon MEMS resonators, bridging the gap between design and physical fabrication requires deep technical expertise and a hands-on mindset. For Fahimeh, Kyocera Technologies is a space for continuous discovery and cross-functional teamwork.

“I work closely with our design and test development engineers, as we have multidisciplinary teams. We work together to make sure that our MEMS resonators will be reliable and work as expected.”

What makes the role at Kyocera particularly rewarding for Fahimeh is the balance between structured cleanroom execution and creative R&D. Beyond standard run sheets, wafer inspections, and data analysis, she has the freedom to take on genuine development tasks.

“Whether it is optimizing a single process step or conducting broader research into new materials that could be utilized in our resonators, there is always room to innovate,” Fahimeh notes. “Kyocera is very open to new ideas. You can bring your suggestions to the group, discuss them together, and work as a team to turn those concepts into real technological improvements.”
