Product Overview

Vertical Semiconductor's sole current offering is a vertical gallium nitride (GaN) power transistor platform, targeting 100-volt to 1.2-kilovolt high-voltage direct-current power conversion applications.

The devices have been demonstrated on 8-inch wafers using standard silicon CMOS manufacturing methods, with first prototype packaged devices planned for early sampling and a fully integrated solution targeted for 2026.

Market Outlook

Demand for vertical gallium nitride power devices is driven by rising AI workload power density in data centers, where power delivery has become a critical bottleneck for compute scaling.

Grid and renewable energy infrastructure adds further demand for higher-voltage direct-current power architectures that seek greater efficiency and smaller power-conversion footprints.

Competitive Advantages

The vertical GaN transistor architecture pushes energy conversion closer to the silicon with less power loss and heat than conventional approaches, which the company reports can improve efficiency by up to 30 percent.

It also enables a roughly 50 percent smaller power footprint in AI data center racks while being manufactured on 8-inch wafers with standard silicon CMOS methods, supporting scalability through existing semiconductor production lines.
