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
