Morimaru Electronics completed Series A financing of 100 million yuan, and hundreds of millions of silicon capacitor products have been delivered

Recently, according to relevant media reports, wafer-level passive device company Morimaru Electronics completed a round of financing of 100 million yuan. This round of investment was jointly led by well-known optical module industry parties and Yaotu Capital, and was followed by Shun Rong Capital. The funds will be mainly used for silicon capacitor and IPD platform technology development, production capacity construction and global market expansion, and promote the application of related products in scenarios such as high-end optical modules and AI chip vertical power supply.

Founded in 2021 and headquartered in Suzhou, Morimaru Electronics is a wafer-level passive device IDM company with full-process capabilities from device design, manufacturing to testing. The company's product layout focuses on silicon capacitors, silicon inductors and IPD passive integrated chips. The products cover IPD devices, IPD integrated substrates, chip capacitors, chip inductors and chip resistors, etc.

Currently, Morimaru Electronics has formed a silicon capacitor and IPD related product system and has wafer-level mass production capabilities. Public information shows that the company uses an 8-inch wafer-level mass production platform and has delivered hundreds of millions of silicon capacitors to leading customers.

In terms of product layout, Morimaru Electronics covers silicon capacitor products in different directions such as high voltage, high density and high frequency, and further extends to IPD integrated passive devices. Related products can be used in AI chips, high-speed optical modules, power management, radio frequency and other scenarios.

As the power consumption of AI chips increases and high-speed optical modules develop towards 800G, 1.6T and other directions, chips and optical modules have put forward higher requirements for power integrity, device miniaturization and high-frequency performance. Morimaru Electronics’ financing will also focus on the development of silicon capacitor and IPD platform technologies, and promote the application of related products in the vertical power supply fields of high-end optical modules and AI chips.

In terms of mass production and customers, Morimaru Electronics has now achieved the introduction of leading customers. According to media reports, the company's silicon capacitor product yield rate is stable at over 95%, its production capacity has reached 300 million units/month, and it has continued to deliver products to leading customers.

Company founder Song Yi said that in the past two years, Morimaru Electronics has received orders from several world-class large customers and completed the introduction of the supply chain. The company expects that starting from 2026, the next four years will become an important stage of business development.

After the completion of this Series A financing, Morimaru Electronics will continue to invest in the research and development of silicon capacitors and IPD platforms, while promoting production capacity construction and global market expansion.
