Infineon Technologies said it was strengthening its long term partnership with Denso to boost its global automotive business - the latter has acquired a slice of the former.

"Both companies aim to jointly enhance their system know-how in established and new technologies like automated driving and electromobility," the pair said in a statement.

Denso has bought a stake in Infineon "in the range of a mid double digit million euro amount".

"We would like to establish optimal semiconductor solutions for in-vehicle electronics systems through strong partnerships with semiconductor companies in order to enhance the competitiveness of automated driving and electrification systems," said Hiroyuki Ina, Denso's senior executive director.

"We are very pleased to expand our already well-established relationship with Denso," said Infineon CEO Reinhard Ploss.

"Our collaboration with Japan's largest and world-leading system supplier is strengthening our links with the Japanese industry as well as our position in the Japanese and global semiconductor market. We welcome Denso becoming a shareholder."

Infineon Technologies booked sales of EUR7.6bn in fiscal 2018 and has about 40,100 employees worldwide. Denso sales were US$48.1bn and it employs 170,000.
