Beyond silicon

Next-generation AI infrastructure demands unprecedented transistor density without compromising energy efficiency.

As silicon approaches its scaling limit, foundries face a critical bottleneck:

The industry lacks the production tools to grow 2D materials on standard 12-inch wafers at commercially viable yields.

North Star™

  1. Purpose-built for wafer-scale 2D TMD growth.

    Our full-stack platform replaces legacy silicon channels with TMDs at the core of each transistor – atomically thin crystals that flawlessly conduct electricity at the sub-nanometer scale.

  2. Engineered Precursor Delivery

    Precise vapor-phase delivery for stable chemistry and repeatable process windows.

  3. Intermediate-Reaction Showerhead

    Multi-channel thermal control enables uniform precursor reactions and wafer-scale distribution.

  4. Foundry-Compatible Wafer Handling

    Automated wafer transfer designed to integrate with industry-standard fab workflows.

Transistors built for the Angstrom era.

Up to

100×

Lower Defect Density

Eliminates micro-voids and interface flaws at atomic scales, unlocking the high manufacturing yields required for 300mm wafers.

Up to

75%

Less Switching Power

Delivers perfect gate control and low-leakage current, allowing AI chips to complete more compute operations with the same energy budget.

Over

2×

Smaller Gate Length

Reduces transistor channel length from using atomically thin 2D materials, enabling continued scaling beyond the sub-1 nm node.

To change what’s possible, we have to question the limits we’ve accepted.

This belief continually drives Dr. Lance Li, Co-founder & Chief Scientist of Nexstrom, and one of the earliest pioneers of 2D material growth.

From being among the first to grow single-crystal MoS₂ since 2012, to leading corporate research at TSMC, Lance has spent his career pushing the boundaries of post-silicon electronics.

His deep expertise in materials science and atomic-layer chemistry, coupled with the team’s experiences in hardware design and semiconductor integration, anchors Nexstrom’s mission: To develop wafer-scale, CMOS-compatible 2D platforms for the next generation of computing.

For Nexstrom, the Angstrom Era isn’t a theory. It’s underway — and we are building the foundation to lead it.
