History

[edit]
Renesas Silicon Valley offices in San Jose, California

Renesas Electronics was established in April 2010 through the merger of Renesas Technology and NEC Electronics.[7] Renesas Technology had been formed in 2003 as a joint venture between Hitachi and Mitsubishi Electric, combining their non-DRAM semiconductor businesses.[4][8] NEC had earlier spun off its semiconductor division as NEC Electronics in 2002.[9][10] The companies had previously separated their DRAM operations into Elpida Memory, which filed for bankruptcy in 2012 and was acquired by Micron Technology.[11]

In December 2010, Renesas Mobile Corporation was formed by integrating Renesas’s mobile business with assets acquired from Nokia.[12] However, the company later exited the mobile sector, transferring LTE assets to Broadcom in 2013 and dissolving the subsidiary in 2014.[13][14]

The 2011 Tōhoku earthquake and flooding in Thailand severely impacted Renesas’s operations.[15] A major restructuring followed, involving the sale of domestic factories and a capital infusion from the Innovation Network Corporation of Japan (INCJ), which became the company's largest shareholder in 2013.[16][17][18][19] Renesas returned to profitability in fiscal year 2013.[20]

From 2016 onward, Renesas embarked on a series of acquisitions to strengthen its automotive and industrial semiconductor portfolio. It acquired Intersil in 2017[21] and Integrated Device Technology (IDT) in 2019.[22][23] In 2021, it purchased Dialog Semiconductor for $5.9 billion,[24][25] followed by additional acquisitions including Celeno Communications,[26] Reality AI,[27] and Steradian Semiconductors.[28]

In March 2021, a fire at the Naka Factory temporarily disrupted production, but operations resumed the following month.[29][30] The company also reopened its Kofu fabrication facility to support power semiconductor production, with operations expected to begin in 2024.[31]

Renesas continued its expansion through 2023 and 2024 with the acquisitions of Panthronics,[32] gallium nitride chipmaker Transphorm,[33][34] and PCB design software firm Altium.[35][36] It also signed a long-term silicon carbide wafer supply agreement with Wolfspeed and entered a strategic partnership with Vietnamese EV maker VinFast.[37][38]

In April 2023, Renesas was added to the Nikkei 225 index,[39] and in December 2022, it received the “Outstanding Asia-Pacific Semiconductor Company Award” from the Global Semiconductor Alliance.[40]

The move doubles Renesas' power semiconductor production capacity starting in 2025. Renesas' back-end assembly and testing operations are distributed globally, with the largest site at Renesas Semiconductor (Malaysia) Sdn. Bhd. in , , , which handles packaging for analog and discrete . Additional back-end facilities include Renesas Semiconductor Package & Test (Suzhou) Co., Ltd. in , , and operations in , , for assembly and testing of microcontrollers and connectivity devices. In , support facilities in locations such as Oita and Yonezawa provide specialized back-end services for high-value products. The company's manufacturing processes target process nodes from 40 nm to 180 nm, optimized for microcontrollers and analog/power devices, enabling high integration and low power consumption. These nodes support embedded and multi-core architectures suitable for automotive and industrial applications. Renesas emphasizes automotive-grade quality standards, with products qualified under AEC-Q100 for reliability in harsh environments. Following the 2011 Great East Earthquake, which disrupted multiple facilities including Naka, Renesas diversified its by expanding overseas back-end operations and reducing reliance on single-site production. For advanced nodes below 40 nm, Renesas partners with foundries such as to outsource fabrication, combining in-house MONOS flash technology with external capacity. In 2025, amid geopolitical risks like U.S.- trade tensions, Renesas prioritizes resilient sourcing through multi-region procurement and supplier diversification to mitigate disruptions. Renesas' front-end facilities support expansions like Kofu targeting increased output for power semiconductors to support EV market growth.
