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
