This ASX semiconductor play is about to solve a major bottleneck

ASX semiconductor play Adisyn (ASX:AI1) is at a pivotal point in its development journey. By this time next year, the company is expected to have delivered a demonstration protype of its graphene disposition technology to build transistor interconnects, an area of semiconductor manufacturing that is starting to become a major bottleneck in advanced chip manufacturing.

Adisyn: An ASX semiconductor play replacing copper with graphene in semiconductor transistors

Adisyn picked up 2D Generation in 2024 and 2D’s technology has been its focus ever since. The problem 2D has been trying to solve is that transistor interconnects are unable to continue being made with copper, and so an alternative material is required.

Transistors are semiconductor devices that regulate or control currents or voltage flow in addition to amplifying and generating these electrical signals. You will have noticed that electronic devices are getting smaller and smaller while being expected to perform more and more. This is good for consumers, but presents a challenge for manufacturers, because transistors need to follow suit (i.e. get smaller and smaller while doing more and more).

But copper interconnects are running into limits. They get so small that the resistance becomes very high, in turn requiring increased power consumption, which also increases heat on the chip. Additionally, current may leak away because the wire is so thin, which leads to errors on the chip.

The industry has been looking into alternative solutions and there is no shortage of them. Other possible materials include nickel, cobalt, rhodium, iridium and ruthenium. But the assumption underpinning 2DG’s technology is that graphene is the best solution. After all, it has high thermal conductivity and strength – 200x more than steel!

2DG has a technology that uses graphene, based on the principles of Atomic Layer Deposition (ALD). It can be done at temperatures much lower than those needed in other methods, is scalable and repeatable, provides precise control of film thickness and creates uniform layers on the transistors.

2025 has been a pivotal year

In 2025, Adisyn has taken major steps in the development of its technology. In March, the company entered into a strategic partnership with the Jan Koum Centre for Nanoscience and Nanotechnology (TAU Nano Centre) at Tel Aviv University. Adisyn is leasing specialised equipment from the TAU Nano Centre, including a Beneq TFS 200 ALD system (pictured).

In parallel, the company has bought an ALD system of its own. 2DG received a customised model with specific capabilities for the company’s graphene deposition process.

2026 will be even bigger

At the current phase of development, the company is aiming to identify 3 precursor candidates and to determine optimal growth conditions. Generation aims to have a Demo Prototype ready by mid-2026, i.e. proof that its technology is working on a 1x1cm chip.

By ‘working’, we mean that graphene interconnects should overcome the limitations of copper in being able to scale down while still working. There should be lower signal delay, lower power consumption, better heat profile, higher density of components and less crosstalk (i.e. signal interference).

Once a full Demo Prototype has been delivered, 2D Generation will seek collaborations in smaller projects to find application areas for its technology other than graphene interconnects.

Major upside ahead

Our friends at Pitt Street Research value Adisyn at $0.29 per share, $0.22 of which is attributable to 2D Generation and A$0.07 to Adisyn’s legacy business.

These figures are a significant premium to the other price. But we think investors should (and can) look to companies including Nanoveu (ASX:NVU) and Weebit (ASX:WBT) for what can happen when semiconductor companies hit development/commercialisation milestones – both of which did this in 2025 and reaped the rewards.
