The Pennsylvania Startup Betting That Silicon Still Has Room to Run
Everyone said the next leap in power electronics had to come from exotic materials. iDEAL Semiconductor bet it could wring more out of plain silicon - and now its chips are shipping from a Minnesota fab.
Global Unichip Corporation (GUC)
The Taiwanese design house that quietly builds other people's AI chips - and reserved 60,000 CoWoS wafers to keep doing it.
Morse Micro
Morse Micro is a fabless semiconductor company based in Sydney, Australia, that designs Wi-Fi HaLow (IEEE 802.11ah) chips for the Internet of Things. Its sub-1 GHz system-on-chips deliver roughly ten times the range of conventional Wi-Fi at a fraction of the power, letting a single access point connect thousands of sensors, cameras and devices across homes, factories, farms and cities. Founded in 2016 by Wi-Fi chip designers Michael De Nil and Andrew Terry, the company has raised more than US$190 million and ships its award-winning MM6108 and second-generation MM8108 silicon to customers worldwide.
SkyeChip
SkyeChip is a Penang-based fabless semiconductor company that designs silicon intellectual property (IP) and custom application-specific integrated circuits (ASICs) for artificial intelligence and high-performance computing. Founded in 2019 by former Intel, Altera and Broadcom engineers, it specialises in advanced memory-interface IP (HBM3E, DDR5, LPDDR5/5x), UCIe die-to-die interconnect, network-on-chip fabrics and RISC-V CPU IP built on 6nm/7nm process nodes. Recognised as Malaysia's first homegrown AI chip designer, SkyeChip listed on Bursa Malaysia's Main Market in May 2026 in the country's largest IPO in 16 years.
XMOS
XMOS is a fabless semiconductor company based in Bristol, UK, that designs the XCORE family of multicore, deterministic processors for embedded voice, audio, AI and control at the edge. Founded in 2005 by a team rooted in the University of Bristol and Inmos transputer heritage, XMOS built its name on far-field voice processing (VocalFusion, the first far-field solution qualified for Amazon Alexa) and now positions XCORE as a 'Generative System-on-Chip' (GenSoC) - silicon whose behaviour can be described in natural language while guaranteeing real-time, deterministic performance.
SPARK Microsystems
SPARK Microsystems is a Montreal-based fabless semiconductor company building ultra-wideband (UWB) wireless transceivers that aim for wire-like performance without the wire. Its patented LE-UWB technology delivers ultra-low latency, high data throughput, and very low power draw, targeting applications where Bluetooth falls short: wireless audio, gaming peripherals, AR/VR and AI wearables, presence detection, and industrial IoT. Founded in 2016 by researchers out of Montreal's engineering community, SPARK has raised roughly CAD $48M+ and is scaling commercial adoption of its second-generation SR1120 transceiver.
AXONNE
AXONNE is a fabless Silicon Valley semiconductor company building high-speed Automotive Ethernet connectivity for the software-defined, AI-defined vehicle. Founded by ex-Marvell engineering leaders, it designs PHY transceivers and bridge chips - led by its Cyton PHY implementing IEEE 802.3ch Multi-Gigabit Automotive Ethernet - that move 1Gbps to 10Gbps over a single twisted pair or coax, wiring cameras, radar and lidar into the compute clusters that drive ADAS and autonomous systems.
SCINTIL Photonics
SCINTIL Photonics is a Grenoble-based, fabless silicon photonics company building the world's first single-chip, DWDM-native laser source for AI data centers. Spun out of CEA-Leti and founded by Sylvie Menezo, its proprietary SHIP (Scintil Heterogeneous Integrated Photonics) process integrates lasers, modulators and detectors onto one manufacturable chip - powering its LEAF Light light engine for co-packaged optics that promises roughly one-sixth the power consumption of conventional pluggable optics. The company raised a $58M Series B in September 2025 with participation from NVIDIA.
Ceremorphic, Inc.
Ceremorphic is a San Jose-based fabless semiconductor startup building energy-efficient AI supercomputing silicon. Founded in 2020 by serial entrepreneur Venkat Mattela, the company taped out a first-of-its-kind 5nm HPC/AI chip on TSMC's most advanced node and is applying the same Hierarchical Learning Processor architecture to data center AI, robotics, automotive, and analog-AI-driven drug discovery.
