Silicon 100: Chiplet work spanning interconnect PHYs to smart substrates

By Majeed Ahmad, EDN | August 18, 2025

While the Silicon 100 report was being compiled and curated to profile the most promising startups in the semiconductor industry in 2025, two prominent chiplet upstarts were already taken. First, Qualcomm announced its acquisition of chiplet interconnect developer Alphawave Semi in the second week of June 2025.

Nearly a month later, Tenstorrent snapped Blue Cheetah Analog Design, another supplier of die-to-die interconnect IPs. These two deals highlight the red-hot nature of the chiplets world and how this new multi-die technology landscape is emerging despite geopolitical headwinds.

In this year’s Silicon 100 report, there are eight startup companies associated with chiplet design and manufacturing work. In the chiplet design realm, DreamBig Semiconductor develops chiplet platforms and high-performance accelerator solutions for 5G, artificial intelligence (AI), automotive, and data center markets. Its core technology includes a chiplet hub with high-bandwidth memory (HBM).
