Infineon's manufacturing processes cover silicon (Si), silicon carbide (SiC), and gallium nitride (GaN) technologies, providing critical support for efficient energy conversion.

Infineon's Development History

Infineon's journey can be considered legendary in the semiconductor industry. Its origins can be traced back to the founding of Siemens in 1847. With Siemens' support, Infineon's predecessor grew to become the world's tenth-largest chip supplier. After spinning off from Siemens in 1999, Infineon quickly established itself in the semiconductor market. In 2006, it spun off its memory business into a wholly-owned subsidiary, Qimonda. In 2019, Infineon acquired Cypress Semiconductor, becoming one of the top ten global semiconductor manufacturers and the world's largest automotive semiconductor supplier.

In recent years, Infineon has further consolidated its leadership in automotive electronics and power semiconductors through strategic acquisitions (such as Cypress) and independent research and development.
