Apr 2023Series ACTC Capital (lead); SL Capital; Nanjing Jiangbei New Area Development Fund; Lianhe Capital; Teda Venture Capital; Xingrui Capital$73MAaltoSemi, founded in 2021 and based in Nanjing, China, specializes in the research, development, testing, and manufacturing of advanced IC packaging substrates, including BT, ABF, and embedded trace substrates for flip-chip chip-scale packages and flip-chip BGA, serving as a high-end supplier connecting chips to circuit boards. The company completed a Series A1 funding round on approximately April 24, 2023, raising over CNY 500 million (about $72.5 million USD), led by CTC Capital with participation from SL Capital, Lanhor Capital (also referred to as Lianhe Capital or Junhai Chuangxin), Teda Venture Capital, Nanjing Jiangbei New Area Development Fund, Xingrui Capital, and existing investors including Gaorong Capital, KQ Capital (or Kunqiao Capital), and Summitview Capital (or Summitview High-tech Venture Capital). This matches the specified investors and approximate date. The funds from the Series A1 round are designated for expanding manufacturing facilities, constructing production lines, and enhancing R&D efforts to support growth in high-end packaging substrates. No post-money valuation, pre-money valuation, revenue, ARR, EBITDA, or valuation multiples are mentioned in any sources covering this specific round. Earlier funding stages are referenced indirectly through prior investors, but details on prior rounds like total raised prior to A1 are inconsistent or incomplete across sources, with one listing a low $3.09M total that appears erroneous given the A1 size. AaltoSemi operates in the competitive semiconductor packaging materials sector amid China's push for domestic chip technology self-sufficiency, focusing on critical components for advanced IC packaging. No traction metrics such as revenue, customer counts, or production volumes near the round date are provided in the sources. Subsequent developments include mentions in 2024 funding trend reports alongside other Chinese chipmakers, but no follow-on rounds for AaltoSemi are detailed here.
