FineMems, a China-based sensor technology provider, has raised RMB200m ($30.6m) in a series D round featuring SoftBank China Capital, the corporate venturing arm of telecommunications and internet group SoftBank.
Changing Innovation Investment, a vehicle launched by securities firm Changjiang Securities, also backed the round, as did venture capital firm F&G Venture.
Founded in 2011, FineMems manufactures micro-electromechanical system sensors used by companies in the automotive, internet-of-things, smart home appliance and industrial control sectors.
The company had previously raised $6.9m in series C-plus funding from semiconductor-focused investment firm CTC Capital in August 2019.
SIG China, an investment vehicle for quantitative trading firm Susquehanna International Group, joined plastic electronics component maker Ningbo Tianlong Electronics to provide an undisclosed amount of series B financing for FineMems in 2015, three years after it secured $4.6m in series A funding from SIG China.
