Sparc FOUNDRY develops and produces photonic semiconductors as part of a strong European photonics ecosystem.
The foundry will produce PICs (Photonic Integrated Circuits) and discrete components based on Group III-V semiconductors It will have the capacity to develop 20,000 wafers per year with different types of technologies based on Group III-V materials, including GaAs (Gallium Arsenide), InP (Indium Phosphide), and GaN (Gallium Nitride). These components will be used by industries around the world in sectors such as automotive, telecommunications, quantum computing, consumer electronics, defense, aerospace and medicine.
The Senior Integration Engineer for RF-GaN Device will be part of the R&D team and play a pivotal role in our GaN foundry team. SPARC Foundry’s RF-GaN Product Line is looking for engineers with industry-relevant experience in developing high-performing Gallium Nitride (GaN) device technologies for high-frequency applications, and to drive innovative fab-based technology development for leading-edge, high-power solutions (>500W) in Vigo, Spain.
As a Senior Process Integration Engineer, you will become a core member of a broader center of excellence in Wide Bandgap (WBG) technology development, driving innovation across technology platforms and bridging the gap between semiconductor processing and circuit performance. Engineers with a MSc or Ph.D. degree and over 8 years of industry-relevant R&D experience in Gallium Nitride technology are strongly preferred.
Essential Responsibilities
This position offers the unique opportunity to develop innovative RF Discrete & MMIC GaN technologies as a Senior Process Integration Engineer and deliver performance and reliability demonstration across technology development qualification milestones from conception through manufacturing installation.
Primary Responsibilities:
Develop & Qualify innovative process sequences and device structures (such as GaN HEMTs or GaN MISHEMTs) that meet our customer's performance, high-power thermal management, reliability, yield, and cost objectives eg. for applications exceeding 500W.
Technical Lead of Technology Transfer Programs: Drive the successful transfer of new GaN technology nodes from R&D phases into high-volume manufacturing, ensuring seamless fab integration.
Optimize Key Fabrication Processes: Collaborate with Fab process-engineers to develop, sustain, and improve critical cleanroom processes, including dry/wet etching, thin-film deposition (CVD, PVD), and Atomic Layer Deposition (ALD).
Contribute to complex, technical projects critical to technology development and fab process qualification goals.
Execute DOE (Design of Experiments) definition, planning, execution, and data-driven analysis of results to achieve device performance and wafer manufacturing targets.
Expanded Responsibilities:
Collaborate actively within cross-functional teams to support innovation, interfacing seamlessly with various engineering groups—including RF design, small & large signal characterization, model verification, failure analysis, unit process module, reliability, manufacturing, and research organizations—to contribute to overall program success.
Education: M.Sc or Ph.D. in Electrical Engineering, Chemical Engineering, Materials Science, Solid-State Physics, or another relevant engineering or physical science discipline.
Years of Experience: 8+ years in an industry-relevant role in semiconductor device & process integration with at least 5+ years of Gallium Nitride (GaN) device & process development & integration experience, preferably RF-GaN HEMTs.
Solid knowledge and expertise of:
(1) Fab fabrication processes such as MOCVD epi, lithography, dry/wet etching, cleaning, deposition (including ALD).
(2) HEMT device physics, TCAD, DOE methods & statistics, and DC & RF parametric characterisation techniques.
Track Record: Demonstrated technical team collaboration and project ownership, advancing the state of the art and innovation through patents, novel processing approaches, or successful technology transfers.
Finally, as all our team we would really like to work with people who share our same passion for technology, photonics, semiconductors, and integrated optics.
