Senior Process Development Engineer - 2D growth

Your Role As a Senior Process Development Engineer – 2D growth, you will lead high-temperature thermal processing, tool qualification and graphene-synthesis baseline development for FabONE. You will drive the release and optimization of 2D-material growth processes, improve thermal-film properties, and establish stable, repeatable graphene-growth recipes. Working on site in our Aachen cleanroom, you will collaborate with Process Integration and Metrology teams to integrate thermal processes into downstream GFET and optical modules. What You’ll Do • Lead high-temperature process development, layer property mapping and recipe optimization for graphene and other 2D materials • Drive tool installation, commissioning, process qualification and system optimization in FabONE • Develop, qualify and stabilize repeatable graphene-growth recipes that meet defect-density and film properties specifications • Support the integration of graphene growth and transfer processes on target 300 mm substrate wafers • Establish SPC baseline charts and routine characterization protocols for daily process monitoring • Use Design of Experiments (DOE), SPC and root-cause analysis to improve process performance and resolve process and/or equipment issues • Collaborate with Process Integration and Metrology teams on film characterization using techniques such as Raman spectroscopy, optical microscopy, sheet-resistance measurement, AFM and SEM • Support inline defect reduction and the continuous improvement of process yield and stability • Create SOPs, safety protocols and technical documentation to reduce single-point-of-failure risks • Cross-train team members to establish reliable operational coverage for furnace processes What You Bring • Deep expertise in high-temperature furnace operations and thermal processing • Hands-on experience with semiconductor process development, process control and baseline stabilization in a cleanroom fab environment • Experience with CVD synthesis of graphene or other 2D materials is a strong advantage • Experience with Thermal Furnace processes is an advantage • A proven track record of commissioning and qualifying process tools and releasing processes into operation • Experience using SPC and DOE methodologies, including tools such as JMP or Minitab • Familiarity with thin-film characterization techniques, including sheet-resistance measurement, Raman spectroscopy, optical microscopy, AFM or SEM • Strong problem-solving and root-cause analysis skills for process and equipment troubleshooting • Excellent communication and collaboration skills, with the ability to work across multidisciplinary engineering teams • Comfortable working in an ISO 5/6 cleanroom while wearing full cleanroom PPE • Comfortable handling wafer cassettes, precursor canisters and high-temperature furnace hardware What We Offer • The opportunity to establish graphene-growth processes for FabONE from qualification through stable operation • A hands-on, cleanroom-based role working with high-temperature processing and 2D-material technologies • A potential career path towards the Senior IC or Technical Principal track, leading the thermal and 2D-material deposition technology roadmap, or towards engineering management leadership Our work culture People Over Processes.
