Intel Shows the Future Beyond Silicon: 2D Transistors Are Coming

Intel Foundry and imec have demonstrated an important step toward the future of post-silicon chips: 2D field-effect transistors that are compatible with 300 mm semiconductor manufacturing.

For more than a decade, 2D transistors have mostly existed in academic labs. The big problem was not the idea itself, but manufacturability. These atomically thin materials are extremely fragile, and many previous demonstrations relied on special research tools and delicate processes that could not easily move into real chip factories.

Now Intel and imec have shown production-compatible modules for 2D FET contacts and gate stacks. The work focuses on transition metal dichalcogenides, including WS₂ and MoS₂ for n-type transistors and WSe₂ for p-type transistors. These materials can form channels only a few atoms thick, which could help extend transistor scaling when silicon reaches its physical limits.

The key achievement is a fab-compatible integration approach. Intel grew high-quality 2D material layers and protected them with oxide stacks such as AlOx, HfO₂ and SiO₂. A selective etching process then enabled top contact formation while helping preserve the fragile 2D channel.

This does not mean 2D chips are arriving tomorrow. Experts expect this technology to matter much later — possibly in the 2030s or even 2040s. But it shows how companies are preparing for the era beyond today’s GAA transistors and future CFET designs.
