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
At Black Semiconductor, we are currently searching for a CD-SEM Expert to join us and support the advanced semiconductor manufacturing and technology development. In this role, you will operate, optimize, and maintain CD-SEM metrology tools to deliver accurate nanoscale measurements on semiconductor wafers.
You will play a key role in enabling process control, yield improvement, and advanced node development by translating critical dimension data into actionable insights for process and integration teams. Working closely with lithography, etch, and metrology engineers, you will help ensure stable and high-performing development and production processes.
In addition, you will support metrology capability building through training activities, documentation, and backup support for broader metrology engineering tasks when required.
To join our team, you should be excited to
Operate CD-SEM tools to perform critical dimension, profile, and defect measurements on semiconductor wafers
Ensure accuracy, repeatability, and reproducibility of CD measurements for process control and yield improvement
Perform preventive maintenance, troubleshooting, and root cause analysis to ensure tool stability and uptime
Collaborate with vendors for equipment repairs, maintenance, and spare parts replacement when needed
Work closely with process, lithography, and etch teams to correlate CD-SEM data with process performance
Generate reports and dashboards on key metrology metrics (e.g., CD bias, LWR, LER) to support process monitoring
Act as backup support for broader metrology engineering activities when required, support training of colleagues and maintain CD-SEM training documentation
Drive improvements in metrology methods and ensure all activities comply with EHS (Environment, Health, and Safety) guidelines
Your Qualifications
Educational background in Electrical/Electronic Engineering, Mechanical Engineering, or related field
5+ years of experience in semiconductor manufacturing environments

Graphene photonics enable optical chip interconnects
Black Semiconductor develops graphene-based photonics that integrate optical components into the outer layers of CMOS-like chips, enabling direct optical chip-to-chip communication. It works by using graphene as a translator to convert electronic signals to optical signals and back, so electrons on silicon can talk to photons through integrated photonic interconnects. This approach differs from traditional silicon photonics or pure electronic interconnects by being CMOS-compatible, wafer-scale, and capable of linking multiple chips as a single high-performance unit while reducing production steps by about 60%. The company aims to move from pilot production to mass manufacturing, building a 300mm wafer facility (FabONE) in Aachen, with pilot production by 2027 and mass production by 2031, backed by a large European funding round and investors.
