Odyssey Semiconductor Announces Technology Development Milestones

• Demonstrates 700 Volt threshold in the Company's lab as part of vertical GaN device development
• New U.S. Patent issued - Validating novelty and establishing protection of the Company's vertical GaN device designs

ITHACA, NY / ACCESSWIRE / March 30, 2022 / Odyssey Semiconductor Technologies, Inc. (OTCQB:ODII), a semiconductor device company developing innovative high-voltage, vertical power switching components based on proprietary Gallium Nitride ("GaN") processing technology, today announced it has reached a technology milestone in its development of the world's most advanced vertical GaN power field-effect transistors (FETs).

Global sustainability trends require new technologies and approaches for power conversion in electric vehicles, solar and wind turbines, data centers and industrial motors. The trend to depart from traditional silicon-based transistors has been underway for over a decade - silicon can no longer meet the voltage and conversion efficiency demanded. Gallium-Nitride (GaN), deployed as lateral (or parallel) conduction FETs, provides efficiency improvements but fail to provide the voltage rating. Silicon Carbide (SiC) provides the voltage rating but falls short on efficiency. However, until Odyssey's recent innovation in vertical GaN, the performance and reliability of these new, predominant approaches have been insufficient.

Odyssey was founded to commercialize vertical GaN FETs. FETs that can provide the conversion efficiency of GaN with the higher voltage rating of SiC. The approach will lead to breakthrough performance for the most demanding applications.

Odyssey has now validated its approach at a 700 V rating while also providing industry-leading efficiency with and remarkably low on-resistance approaching 1mOhm-cm². These devices also exhibit very low gate leakage and can be operated in a mode where they are normally "off". Technology validation can begin on these 700 V devices while an extension of the same architecture to the next milestone of a 1200 V rating or better is completed.

Odyssey, with global headquarters in Ithaca, New York is developing this technology in their own manufacturing facility. As the U.S. needs to strengthen domestic semiconductor manufacturing, Odyssey is showing its commitment with its own wafer fabrication facility. This also streamlines the technology and product development processes with close collaboration between R&D and the fab.

The Company is also announcing today that the United States Patent and Trademark Office recently approved U.S. Patent 11,251,295, which issued February 15^th, 2022, with respect to key aspects of Odyssey's vertical GaN technology. The Patent is entitled "Vertical field effect transistor device and method of fabrication" and relates to a method of fabricating a high voltage switching device using GaN layers and materials. Odyssey Semiconductor now has two issued U.S. patents, and has filed many other related claims for the vertical GaN device and related technology.

CEO Commentary

"This 700 V milestone validates our industry-leading efficiency and remarkably low on-resistance. Odyssey is on-track to deliver 1200 V vertical GaN FETs in 2022 for a handful of customers who have already requested engineering samples. We are thrilled the U.S. Patent and Trademark Office has granted our U.S. patent. This strengthens Odyssey Semiconductor's leadership position in vertical GaN devices and related technology," said Rick Brown, co-founder, interim CEO, CTO, and Board member. "Our patent is one of many that will help protect Odyssey's key aspects on our GaN devices."

"Our goal is to fully protect our GaN devices using both patent rights and trade secrets," concluded Brown.
