Silicon Box, a Singapore-based semiconductor design and manufacturing firm, has secured US$200 million in a series B funding round from various investors, including BRV Capital, Event Horizon Capital, Lam Capital, and TDK Ventures.

Its co-founders Sehat Sutardja, Weili Dai, and Byung-joon Han also participated in this funding round. With this investment, the company claims that its valuation has now surpassed US$1 billion, hitting unicorn status.

Founded in 2021, Silicon Box specializes in chiplet architecture, helping chip designers transition from single-chip processing.

In a statement, the company pointed out how costly packaging methods have hindered semiconductor chips’ performance and given an upper hand to the industry’s most well-funded players. According to Silicon Box, chiplets enable “dramatically better performance, smaller device sizes, and improved device reliability.”

With the fresh funds, the company aims to expand its chiplet tech globally and support the development of large language models (LLMs), generative AI, mobile computing, data centers, and automotive tech.

Additionally, the company said its US$2 billion factory in Singapore has been mass-producing chiplets for early customers since October 2023. Silicon Box has ramped up hiring to support 24/7 operations at the 750,000-square-foot facility, which was opened in July 2023.

The surge in demand for AI has driven the semiconductor industry over the past year. The global semiconductor market is projected to grow 13.1% this year to a record US$588 billion.
