ONsemi Semiconductor was founded in 1999. The company was originally a spinoff of Motorola's Semiconductor Components Group. For over 60 years, onsemi and its ancestors have been leading the world’s greatest technology advancements. In 2016, onsemi acquired Fairchild Semiconductor to become a top semiconductor manufacturer. Fairchild was founded in 1957 to build transistors out of silicon rather than the more common germanium. However, not only does onsemi combine the heritage of industry giants Motorola and Fairchild, but also Cherry Semiconductor, AMI Semiconductor, SANYO Semiconductor, Aptina Imaging Corporation, SensL Technologies and many others.

ONsemi's Purpose

Technology continues to shape our future. It helps solve some of the world’s most challenging problems, such as generating renewable energy, providing safer transportation, improving healthcare, and connecting the globe. onsemi is at the forefront of intelligent technology advancements, offering the power and sensing solutions that are the essential building blocks of change. We are building a sustainable and intelligent world through technology.

ONsemi's Mission
