Senior Process Engineer – Dry Etch (f/m/d)

Permanent employee, Full-time · Aachen

About us

We see the semiconductor industry as a realm of possibility. We see opportunity. We see the profound impact that our graphene solutions will have in transforming the industry. We invite you to join us in driving change with our fundamentally human-centered approach, uniting bright minds around a shared vision. The vision is: Prove to everybody that you can make a fundamental change. Prove with your knowledge and skills how things can be done differently. Together, we can change the paradigm of how the world connects

About our technology

The semiconductor industry’s growing demand for more powerful chips with higher bandwidth and lower power finds its solution in our technology. We connect chips to high-throughput, low-delay computing networks. The key lies in harnessing the physical properties of graphene to combine electronic computing with photonic communication, allowing countless chips to interact almost as if they were one. Our graphene photonic innovation increases computing power and efficiency to a new order of magnitude

In short, we connect chips to create powerful and energy-efficient networks, overcoming connectivity limitations in the semiconductor industry. We deliver the graphene solution

The Role

Black Semiconductor is looking for a highly skilled and experienced Senior Process Engineer - Dry Etch (f/m/d) to join our semiconductor fab team. In this pivotal role, you will take ownership of dry etch processes across new and existing layers in a state-of-the-art facility. Your work to develop, stabilize, and scale etch processes will directly impact device performance, yield, and long-term manufacturing robustness
The ideal candidate will play a critical role across the engineering team, working closely with Integration, Equipment Engineering, and internal/external partners to define etch strategies, qualify processes, and establish strong process control in a fast-paced pilot-line environment

To join our team, you should be excited to

Develop, qualify, and sustain dry etch processes for assigned process modules, supporting both newlayerbring-up and ongoing production needs
Execute and support process qualification activities in close collaboration with Equipment Engineering and Integration teams
Define andoptimizeetch process windows, focusing on critical metrics such as CD control, profile, selectivity, uniformity, and defectivity
Collaborate with the BLK Integration team to support future applications and process modules aligned with our long-term technology roadmap
Drive root cause analysis and corrective actions for process excursions, yield issues, and integration challenges
Develop and implement robust process control methodologies, including SPC, DOE-based optimization, and processmonitoringstrategies
Mentor technical engineering team members and support the development of less-experienced engineers on dry etch processes and best practices

Your Qualifications

3–7 years of experience developing and sustaining dry etch processes on 200mm and/or 300mm semiconductor platforms
Proven experience with process qualification, optimization, and ramp-up in a fab or pilot-line environment.
Strong understanding of plasma etch fundamentals, including process chemistry, profile control, selectivity, and integration dependencies
Hands-on experience working with RIE-based platforms (e.g., LAM, TEL, AMAT), from a process engineering perspective
Familiarity with advanced etch techniques such as Atomic Layer Etch (ALE) is a strong plus
Experience applying DOE, SPC, and data-driven methodologies to improve process stability and yield
Ability to thrive in a startup environment with a hands-on, proactive mindset and a strong sense of ownership
Strong communication skills and fluency in English
