Announcement PDF Adisyn Ltd | ACN 155 473 304 | 1300 331 888 | 2 – 3/4 McGrath Road, Henderson WA 6166 | adisyn.com.au ASX Announcement 17 November 2025 Adisyn Achieves Key Technical Milestone in Graphene Deposition Process Highlights • Instrumental technical milestone achieved in Adisyn’s pre-clean stage of its graphene deposition development program. • Successful validation of a key sub-process within the pre-clean sequence effectively prepares wafer surfaces for graphene growth. • Confirms the Company’s process architecture is performing to design expectations and ready to enter broader deposition trials. • Represents another step forward toward enabling direct graphene growth on semiconductor wafers - a breakthrough goal for the industry. • Development continues to advance under Adisyn’s globally experienced, multi-disciplinary R&D team and international collaborations with Tel Aviv University, imec and the EU Connecting Chips Initiative. Adisyn Ltd (ASX: AI1) (“Adisyn” or “the Company”) is pleased to announce that its wholly owned subsidiary 2D Generation (2DG) has successfully achieved the initial phase of developing a wafer (or coupon level) surface pre-clean step, one of several sub-processes within the overall pre-clean stage within its proprietary low- temperature graphene deposition process. This achievement represents an important technical milestone in Adisyn’s program to develop a repeatable, scalable, low-temperature graphene deposition process, aimed at enabling the next generation of graphene- based semiconductor interconnects - a breakthrough that could redefine how next-generation chips are made. Building a Pathway to Next-Generation Semiconductor Performance Adisyn’s graphene program targets one of the most significant challenges in advanced semiconductor manufacturing - the physical limits of copper interconnects at sub-2nm process nodes. As chip features shrink, copper interconnects become less efficient, increasing electrical resistance, heat, and energy use. These limitations threaten the continued miniaturisation and performance scaling that underpin computing and AI advancement. Graphene, a single layer of carbon atoms arranged in a hexagonal lattice, offers superior electrical conductivity, heat resistance, and mechanical strength, making it a promising alternative for interconnect materials. However, traditional graphene growth processes require temperatures too high for semiconductor environments (900–1000°C), making integration impractical. Adisyn’s patented low-temperature Atomic Layer Deposition (ALD) approach has the potential to overcome this challenge, allowing direct graphene growth on semiconductor wafers within standard fabrication conditions. Adisyn Ltd | ACN 155 473 304 | 1300 331 888 | 2 – 3/4 McGrath Road, Henderson WA 6166 | adisyn.com.au Success would enable faster, smaller and more energy-efficient chips powering the next generation of AI, computing and communications technologies. Technical Progress: Initial Pre-Clean Step Created The pre-clean stage is the first and one of the most crucial elements of Adisyn’s graphene growth sequence. It prepares the wafer surface for atomic-scale film deposition by removing residual contamination and optimising surface chemistry. Figure 1: Process sequence for Phase 1 development activities 2DG’s research team has now successfully validated one of the major sub-processes within this stage - demonstrating that the Company’s low-temperaturepre-treatment can effectively prepare wafer surfaces for subsequent graphene deposition. This achievement confirms that the Company’s process architecture is operating as expected and provides confidence to proceed into the next major experimental phase. Additional sub-steps within the pre-clean stage are being refined in parallel as Adisyn continues to improve the metal surface compatibility with graphene deposition.. Next Phase: Entering Deposition Trials and Process Parameter Optimisation Following this achievement, Adisyn and 2DG will now: • Commence extensive deposition trials using multiple carbon-ring-based precursor compounds. • Continue refining the remaining sub-processes within the pre-clean stage to improve surface uniformity and reproducibility. • Optimise deposition parameters including plasma power, gas flow rates, pressure, and temperature. • Characterise resulting films to assess structure, crystalline quality, and electrical conductivity. • Iterate findings to progressively converge on a full, scalable graphene growth “recipe.” This experimental campaign will continue through late 2025 and into 2026, consistent with the Company’s previously disclosed development roadmap (ASX: 6 August 2025). Adisyn Ltd | ACN 155 473 304 | 1300 331 888 | 2 – 3/4 McGrath Road, Henderson WA 6166 | adisyn.com.au Comment – Kevin Crofton, Chairman, Adisyn Ltd “Validating this key sub-process within our pre-clean stage is a meaningful technical advancement and a strong indicator that our low-temperature approach will work as designed. The ability to effectively prepare wafer surfaces at semiconductor-compatible temperatures is essential to the success of our overall deposition process. We are now expanding our efforts into deposition trials while continuing to refine and integrate the remaining pre-clean sub-processes.” Outlook and Next Milestones Over the coming quarters, Adisyn will: • Continue iterative development across all pre-clean parameters. • Undertake broader coupon testing of graphene precursor candidates and their deposition parameters. • Begin evaluating scalability and wafer-level deposition. The Company remains on track to deliver progressive technical validation through 2025 and into early 2026 and will provide further updates as additional technical milestones are achieved.
