Singapore chiplet factory already shipping, raises US$200 million
Silicon Box Pte. Ltd. a startup with a chiplet packaging factory in Singapore, has raised US$200 billion in its Series B funding round.
The company was founded in 2021 by the founders of chip company Marvell – Sehat Sutardja and Weili Dai – and experienced chip packaging executive Byung Joon (BJ) Han.
All three founders were investors in the round. Other strategic investors into Silicon Box include BRV Capital; Event Horizon Capital; Grandfull Convergence Fund; Hillhouse Capital; the corporate venture arm of Lam Research, Lam Capital; Maverick Capital; Prasedium Capital; Tata Electronics; TDK Ventures; and UMC Capital. The Series B takes the valuation of Silicon Box above US$1 billion.
The company also announced that its 750,000 square foot facility has been in mass production for early customers since October 2023, shortly after the formal opening of the factory in July 2023 (see Singapore opens US$2 billion chiplet factory). The facility is set up to help customers design chiplets and then assemble and package them within its factory using “sub-5nm” technology on rectangular, large-area interposers.
Han, who serves Silicon Box as CEO, was formerly CEO of STATS ChipPAC, acquired by JCET in 2015. Sutardja and Han have more than 800 US patents between them and a long history of collaboration.
“Silicon Box is well poised to solve the semiconductor industry’s challenges for fast adoption of chiplets. We are leading the pack to bring high performance, power-optimized, affordable, and scalable solutions that enable next-gen large language models (LLM), generative AI, automotive, data centers, and mobile computing globally,” said Han, in a statement. “Our state-of-the-art factory and advanced panel level packaging are delivering a solution to scale high growth markets, such as AI accelerators, to the masses. This is our first multibillion-dollar factory and we are eager to scale rapidly to support our customers and partners.”
Expansion plans for the Singapore factory reflect a severe shortage in advanced packaging solutions.
