- **Company:** Black Semiconductor GmbH
- **Location:** Aachen, Germany
- **Employment:** full-time
- **Work type:** hybrid
- **Posted:** 2026-10-16
- **Last confirmed live:** 2026-10-19
- **Apply:** https://jobs.ashbyhq.com/blacksemiconductor/5ee52aaa-1206-433a-b85c-f7d63b05bb88

## Job description

## 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
