Texas Instruments has announced the beginning of the production of gallium nitride-based power semiconductors at its factory in Aizu, Japan. Coupled with its existing GaN manufacturing in Dallas, Texas, TI will now internally manufacture four times more GaN-based power semiconductors, as Aizu ramps to production.

"Building on more than a decade of expertise in gallium nitride (GaN) chip design and manufacturing, we have successfully qualified our 200mm GaN technology – the most scalable and cost-competitive way to manufacture GaN today – to start mass production in Aizu," said Mohammad Yunus, TI's senior vice president of Technology and Manufacturing. "This milestone enables us to manufacture more of our GaN chips internally as we grow our internal manufacturing to more than 95 % by 2030, while also sourcing from multiple TI locations, ensuring a reliable supply of our entire GaN portfolio of high-power, energy-efficient semiconductors."

The power of GaN technology

An alternative to silicon, GaN is a semiconductor material that offers benefits in energy-efficiency, switching speed, power solution size and weight, overall system cost, and performance under high temperatures and high-voltage conditions. GaN chips provide more power density, or power in smaller spaces, enabling applications such as power adapters for laptops and mobile phones, or smaller, more energy-efficient motors for heating and air conditioning systems and home appliances.

Today, TI offers the widest portfolio of integrated GaN-based power semiconductors, ranging from low- to high-voltage, to enable the most energy-efficient, reliable and power-dense electronics.

"With GaN, TI can deliver more power, more efficiently in a compact space, which is the primary market need driving innovation for many of our customers," said Kannan Soundarapandian, vice president of High-Voltage Power at TI. "As designers of systems such as server power, solar energy generation and AC/DC adapters face challenges to reduce power consumption and enhance energy efficiency, they are increasingly demanding a reliable supply of TI's high-performance GaN-based chips. TI's product portfolio of integrated GaN power stages enables customers to achieve higher power density, improved ease of use and lower system cost."

Further, with the company's proprietary GaN-on-silicon process, more than 80 million hours of reliability testing, and integrated protection features, TI GaN chips are designed to keep high-voltage systems safe.

Most advanced GaN manufacturing technology available today

Using the most advanced equipment available for GaN chip manufacturing today, TI's new capacity enables increased product performance and manufacturing process efficiency, as well as a cost advantage.

Also, the more advanced, efficient tools used in TI's expanded GaN manufacturing can produce smaller chips, packing even more power. This design innovation can be manufactured using less water, energy and raw materials, and end products that use GaN chips enjoy these same environmental benefits.

Scaled for future advances

The performance benefits of TI's added GaN manufacturing also enable the company to scale its GaN chips to higher voltages, starting with 900V and increasing to higher voltages over time, furthering power-efficiency and size innovations for applications like robotics, renewable energy and server power supplies.

In addition, TI's expanded investment includes a successful pilot earlier this year for development of GaN manufacturing processes on 300mm wafers. Further, TI's expanded GaN manufacturing processes are fully transferable to 300mm technology, positioning the company to readily scale to customer needs and move to 300mm in the future.

Committed to responsible, sustainable manufacturing

Expanding supply and innovation in GaN technology is the latest example of TI's commitment to responsible, sustainable manufacturing. TI has committed to use 100 % renewable electricity in its U.S. operations by 2027, and worldwide by 2030.
