Graphene photonics enable optical chip interconnects
Your Role
As an ALD Lab Working Student, you will support the daily operation of our Atomic Layer Deposition (ALD) tool and the relevant metrology tools in the FabONE cleanroom in Aachen.
Working alongside our ALD process engineers, you will prepare samples, perform routine thin-film characterization, and maintain accurate laboratory records. This is a hands-on opportunity to gain practical experience with semiconductor processing, metrology tools, and cleanroom operations while contributing to our ongoing research and development activities.
What You’ll Do
Prepare samples for ALD and characterization runs.
Perform routine thin-film measurements using spectroscopic ellipsometry, Raman spectroscopy, optical microscopy and AFM
Support senior ALD process engineers with setting up tool test runs and recording operational parameters
Handle delicate samples and cleanroom equipment in accordance with established safety and quality procedures
Document characterization results and upload structured metrology data to central repositories
Organize measurement data and prepare clear summaries of film-characterization results
Help establish and maintain an inventory system for chemicals and precursors
What You Bring
Current enrolment in a bachelor’s or master’s program in materials science, physics, chemistry, mechanical engineering, electrical engineering or a related field, ideally in the last year.
A basic understanding of thin-film characterization methods such as ellipsometry, Raman spectroscopy, optical microscopy or AFM
Strong attention to detail and the ability to handle delicate samples accurately
An interest in semiconductor processing and a willingness to learn cleanroom protocols
Basic proficiency in data logging, documentation and data visualization using Excel or Python
Good communication skills in English
The ability to work effectively and reliably within a laboratory team
What We Offer
Hands-on experience with ALD processes, thin-film characterization and semiconductor laboratory operations
Practical training in cleanroom safety, sample preparation and metrology equipment
The opportunity to work with spectroscopic ellipsometry, Raman spectroscopy, optical microscopy and AFM
Close collaboration with experienced ALD process engineers in our FabONE facility in Aachen
The opportunity to contribute directly to the organization and efficiency of an active research and development laboratory

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.
