Company Overview
About Silicon Box
Silicon Box is a Singapore-based semiconductor design and device integration company founded in 2021 by Byungseok Lee that specializes in advanced chiplet packaging — one of the most critical and technically demanding steps in the semiconductor manufacturing process. As AI chips, high-performance computing (HPC) processors, and power electronics grow more complex, traditional monolithic chip design has reached physical limits. Chiplet architecture — assembling multiple specialized dies into a single package — has emerged as the primary solution, and Silicon Box provides the advanced panel-level packaging technology that makes high-performance chiplet integration commercially scalable.
Business Model & Competitive Advantage
In July 2023, Silicon Box launched its $2B state-of-the-art advanced packaging fabrication facility in Singapore's Tampines Wafer Park — a 73,000 square meter facility designed to manufacture chiplet interconnections for AI, electric vehicles, and wearables at scale. Mass production began in late 2023, and by October 2025, Silicon Box had shipped 100 million units from the Singapore facility — a milestone that validates the commercial readiness of its panel-level packaging technology. The company raised $99.86M in a Series B2 round in August 2024 led by US-based Prysm Capital and has been seeking an additional $150M to accelerate expansion of the Singapore factory.
Competitive Landscape 2025–2026
In December 2024, Silicon Box announced a €3.2B ($3.5B) new advanced packaging facility in Novara, northern Italy — a major investment signaling European semiconductor sovereignty ambitions and extending Silicon Box's geographic footprint beyond Asia. Initial production at the Italian facility is planned for Q1 2028. The company is currently discussing investment from Indonesia's sovereign wealth fund (INA) for its next Singapore expansion, reflecting broad strategic interest from governments seeking advanced semiconductor manufacturing capabilities.
