ROHM Co., Ltd.
ROHM Co., Ltd.
ROHM Co., Ltd. is an electronic parts manufacturer headquartered in Ukyo-ku, Kyoto City, Kyoto Prefecture. The name of the semiconductor manufacturer "ROHM" combines the initial letter "R" of resistors, which was the product of the company's founding, with the unit of resistance, Ω. "R" also stands for reliability, representing ROHM's policy of putting quality first. In April 2024, the company absorbed its subsidiary Lapis Technology, strengthening its development capabilities for high-value-added LSI products.
