Revolutionizing Semiconductor Growth: AI-Driven Autonomous Control of Molecular Beam Epitaxy Pioneered by PDI and Bizmuth MBE

In a groundbreaking collaboration announced in June 2025, the Paul Drude Institute for Solid State Electronics (PDI) in Berlin and the London-based tech firm Bizmuth MBE Ltd. have embarked on an ambitious project to merge cutting-edge artificial intelligence with the ultra-precise process of molecular beam epitaxy (MBE). This pioneering effort aims to integrate large language models (LLMs) and multimodal AI technologies directly into the autonomous operational control of MBE systems — a feat that, if successful, promises to transform how semiconductor materials are synthesized in both research and industrial environments.

Molecular beam epitaxy has stood at the forefront of semiconductor materials science since its inception in the 1960s. Renowned for its ability to deposit atomically defined layers of materials under ultra-high vacuum conditions, MBE remains a gold standard in producing high-purity crystalline films indispensable for cutting-edge electronics and quantum devices. Despite its precision, the traditional MBE process heavily depends on manual interventions, relying on operator expertise to adjust deposition parameters — a factor that introduces variability and limits throughput scalability.

The collaboration targets one of the most critical and commercially relevant material systems in semiconductor technology: Gallium Nitride (GaN). Not only is GaN foundational for high-power electronic devices and energy-efficient lighting such as LEDs, but it also plays a pivotal role in high-frequency telecommunication components. Leveraging extensive experimental datasets amassed by PDI over decades, the AI system will initially focus on optimizing GaN growth protocols, laying a robust groundwork before branching out to more complex and less understood materials where experimental tuning via conventional trial-and-error methods is inefficient and costly.

What sets this initiative apart from prior AI-assisted approaches is the ambition for full autonomy during growth. Unlike advisory AI systems that generate feedback but defer to human judgment, the proposed platform is designed for active, real-time decision-making controlling growth parameters dynamically throughout the deposition process. This environment-responsive AI will be deployed on local edge computing hardware embedded within the MBE apparatus itself, a strategic choice that mitigates data security risks and eliminates dependence on external cloud services, thereby aligning with stringent research and industrial confidentiality requirements.

This advanced integration of multimodal AI—combining data streams like sensor signals, optical diagnostics, and growth chamber parameters with natural language understanding—aims to significantly enhance reproducibility and throughput in semiconductor synthesis. By minimizing human intervention, the system is projected to reduce operator-induced variability, minimize material waste arising from miscalibrated runs, and shorten downtime due to manual adjustments or error correction. Such improvements could accelerate discovery cycles and ease the transition from experimental findings to scalable production.

PDI’s longstanding expertise forms the cornerstone for this ambitious project. Operating eleven MBE systems at its Berlin headquarters, the institute contributes an unparalleled experimental foundation for training and validating the AI models, specifically within Gallium Nitride growth. This partnership represents a synergistic fusion of PDI’s seminal materials science knowledge with Bizmuth’s pedigree in AI-driven manufacturing software development, drawing on their co-founder team’s extensive experience that spans startup innovation and semiconductor technology advancements.

Professor Roman Engel-Herbert, Director of PDI, articulated the profound implications of this partnership, highlighting the convergence of industrial pragmatism and pioneering research that it embodies. Engel-Herbert expressed optimism that this endeavor heralds a new era in materials synthesis, wherein automation and intelligence converge to unlock previously unattainable performance metrics. Such a paradigm shift promises to expedite not only GaN-related device development but also the broader spectrum of compound semiconductors and advanced nanomaterials.

From Bizmuth’s perspective, CEO Isabella Lorente underscored the strategic inflection point represented by this collaboration. For years, the company has envisioned a future where artificial intelligence transcends support functions to assume direct leadership in guiding laboratory processes. Partnering with Dr. Faebian Bastiman, a leading MBE authority and Bizmuth’s Chief Technology Officer, and tapping into PDI’s world-class scientific team, the company aspires to bring this vision to tangible fruition through the creation of a fully autonomous MBE controller operational within months.

The implications of such an autonomous MBE system extend beyond efficiency gains. With AI capable of nuanced, context-aware adjustments, the technology promises to explore parameter spaces far more comprehensively than human operators, identifying novel growth regimes and emergent material properties that could be pivotal for the next generation of electronics and photonics. Additionally, embedding this intelligence at the edge offers researchers real-time insights and adaptive feedback loops that enhance not just production quality but fundamentally enrich understanding of complex epitaxial processes.

Technically, this innovation hinges on sophisticated integration between the physical MBE apparatus and AI algorithms capable of interpreting varied data modalities — from substrate temperature profiles and atomic flux rates to in-situ spectroscopic signals — and transforming those inputs into actionable control commands. Training such AI requires large, high-quality datasets and iterative reinforcement learning cycles, made possible by PDI’s archives and Bizmuth’s software infrastructure. The ensuing synergy is expected to establish a new benchmark for automated materials growth, setting a precedent for other thin film deposition and nanofabrication techniques.

Looking forward, the collaboration pledges to deliver a fully operational AI-controlled MBE system by the close of 2025. Successful implementation could rapidly catalyze widespread adoption across research institutes and semiconductor manufacturers, fostering a paradigm where intelligent automation accelerates innovation while enabling sustainable, resource-efficient fabrication methodologies. This synergy of AI and materials science stands to redefine experimental workflows, making them smarter, faster, and more adaptive to the increasingly intricate demands of next-generation technologies.

In essence, this joint venture between PDI and Bizmuth MBE Ltd. is more than a technological milestone; it is a visionary leap toward harmonizing state-of-the-art AI with the delicate artistry of atomic-scale materials engineering. As semiconductor demands grow ever more exacting in the realms of quantum computing, energy systems, and high-speed communications, such intelligent autonomous control systems may become indispensable tools driving the future of materials science.
