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.

Responsibilities

• 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

Requirements

• 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

---

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
