Building a new component for a semiconductor supply chain is a procurement officer's nightmare. The process is measured in years, the qualification cycles are brutal, and the cost of failure is a fab line standing idle. For a startup, the only viable entry point is a material breakthrough so significant it justifies the risk. AirMembrane, a Tsukuba-based deep-tech company, is betting its automated graphene synthesis is exactly that kind of wedge.
The company is commercializing ultrathin membranes, known as pellicles, for extreme ultraviolet (EUV) lithography, the process used to print the smallest features on the most advanced chips. Today's pellicles are a bottleneck; they degrade under intense EUV light, reducing yield and increasing cost. AirMembrane's proposition is a pellicle made from multilayer graphene, which the company claims offers ultra-high light transmittance and superior durability [AirMembrane]. The technical bet is matched by a commercial one: that its proprietary continuous synthesis and automated-transfer processes can move graphene from the lab bench to a production line [Global Brain].
The manufacturing wedge
For AirMembrane, the product is only half the story. The company's stated differentiation is a focus on manufacturability, a deliberate pivot from pure research. Its core intellectual property lies not just in the graphene material itself, but in the processes to make it at scale. This includes an automated transfer technology that can stack graphene layers with precision, a step critical for creating the uniform, defect-free membranes needed for lithography [AirMembrane, March 2021].
The company's trajectory reflects this engineering focus. Co-founder Masataka Hasegawa, who took over as President and CEO in June 2024, has led manufacturing and commercialization efforts from the start [AirMembrane, June 2024]. The founding team, including former AIST researcher Yoshinori Koga, provides the materials science foundation, but the recent capital infusion is squarely aimed at building production capacity.
Funding a production ramp
AirMembrane has raised capital in a steady cadence, with the clear objective of scaling its manufacturing technology. The rounds have grown in size, signaling investor confidence in the technical milestones reached.
| Date | Amount (¥) | Lead Investor(s) | Stated Use of Funds |
|---|---|---|---|
| August 2024 | 100 million | Global Brain, Central Japan Seed Fund | Initial production technology development [AirMembrane, August 2024] |
| By May 2025 | 150 million (total) | Multiple, including Joyo Capital Partners | Production tech and hiring [GrowthStock, May 2026] |
| October 2026 | 850 million | Global Brain | Building manufacturing capability, recruiting, pilot and mass-production lines [Global Brain, October 2026] |
The October 2026 round of ¥850 million (approximately $5.6 million) is the most substantial to date and explicitly targets the build-out of pilot and mass-production lines [Global Brain, October 2026]. This capital runway is supplemented by non-dilutive funding, including a ¥293 million research project with Japan's New Energy and Industrial Technology Development Organization (NEDO) focused on graphene EUV pellicles [NEDO].
An academic spinout with government backing
The company's origins are deeply rooted in Japan's national research infrastructure. Spun out from the National Institute of Advanced Industrial Science and Technology (AIST) in 2017, AirMembrane carries the designation of an "AIST Start-Up" [AirMembrane]. This connection provides access to deep technical expertise and, as evidenced by the NEDO grant, aligns with national priorities for advanced materials and semiconductor sovereignty.
This institutional support extends to the regional level. In 2026, AirMembrane was selected for two Ibaraki Prefecture programs: the Advanced Technology Commercialization Promotion Subsidy and the Growth Program for Deep-Tech Venture Companies [AirMembrane, July 2026]. While the monetary value of these selections is not disclosed, they signal local government validation and provide potential non-dilutive resources for scaling operations.
The path to a first purchase order
The most significant unanswered question for any hardware deep-tech company is the timeline to a commercial contract. AirMembrane's public materials do not name semiconductor equipment makers or chip manufacturers as customers. The journey from a research prototype to a qualified, production-ready component inside an ASML lithography tool is long and fraught. The company must now execute on its manufacturing build-out, produce consistent samples, and navigate the stringent qualification processes of tier-one suppliers.
Its competitive set includes other Japanese firms exploring advanced materials for semiconductors, such as Meijo Nano Carbon and ExtenD Inc. The real competition, however, is the incumbent pellicle technology and the immense inertia of the existing supply chain. AirMembrane's answer to this is a multi-pronged risk mitigation strategy, evident in its funding structure and product diversification.
- Technical de-risking. The parallel development of graphene TEM grids and FET chips provides earlier, lower-volume revenue streams and serves as a proving ground for its core synthesis and transfer processes [AirMembrane].
- Financial de-risking. Blending venture capital with substantial government grants reduces dilution and aligns the company's milestones with public policy goals.
- Commercial de-risking. Focusing on manufacturability from the outset is designed to answer the foremost question of any potential buyer: can you make enough of it, reliably?
The ideal customer profile is clear, if distant: the process integration engineers and materials sourcing managers at the world's leading logic chipmakers, who are perpetually hunting for yield-improving innovations. For them, a graphene pellicle that lasts longer and transmits more light is a compelling value proposition, but only if it can be sourced as a reliable component.
AirMembrane's next twelve months will be defined by its ability to transition from a promising R&D project to a demonstrable pilot production facility. The ¥850 million gives it the capital to try. Success would mean moving the conversation from technical papers to performance specifications and supply agreements. In the high-stakes game of advanced semiconductors, that is the only metric that ultimately counts.
