Hafnia Gate Dielectrics for Energy Conversion
Category: Other
Developers: Sandia National Laboratories
Product Description:With the rapid expansion of AI and data centers, as well as global electrification, the electrical grid faces immense pressure. High-power semiconductors are needed to minimize energy losses. Over $2 trillion of electricity is processed annually in the U.S., and power electronics are estimated to consume 30-40% of this energy. A one percent reduction in losses could save $500 million to $1 billion annually. Advancing power semiconductor technologies is critical for a more efficient and sustainable energy infrastructure. The introduction of hafnia gate dielectrics for WBG semiconductors represents a groundbreaking shift in value for cost-sensitive applications, particularly in the transportation and smart grid sectors. This advance signifies a transformative leap in capability and cost efficiency that is unlikely to be matched by conventional scaling over the next 15 years. As high-k gate dielectrics' advantages are realized, large-scale markets in solid-state electrical substations, diverse transportation modes (land, sea, and air), and rugged applications in harsh environments will emerge. This pioneering material is the first commercially available hafnia gate dielectric for WBG semiconductors, primed for immediate manufacturing.
