ROHM: Next-generation semiconductor gallium nitride will be mass-produced by spring 2022

ROHM will start mass production of gallium nitride (GaN) semiconductors, considered a new generation of semiconductors, by spring 2022. This is a "power semiconductor" that can improve power supply and control efficiency. Compared with previous silicon semiconductors, the new product is said to reduce current switching losses by 60%. ROHM will build production equipment at its factory in Hamamatsu, Japan, and supply it first for 5G base stations.

ROHM will mass-produce products that can withstand 150 volts for use in data centers and communication base stations. In September 2021, sample availability has already started. The new product adopts a structure in which a gallium nitride layer is formed on a silicon wafer, and ROHM will manufacture it at various bases at home and abroad, including the Hamamatsu factory.

ROHM aims to increase the operating income of the semiconductor component business by 1.5 times the current level to 210 billion yen by the fiscal year 2025 (ending March 2026).
