1. Why the substrate matters
Every transistor sits in, or on, a few hundred nanometres of crystal; the rest of the wafer is mechanical support and, often, a liability. Silicon won because it combines a moderate bandgap (1.12 eV), a native oxide (SiO2) of excellent quality, and the ability to be grown as near-perfect single crystals… Read More
Most of the AI conversation stops at the chip. At SEMICON West 2026 I sat down with René Jonker, Chief Product Officer of Soitec, to talk about what sits underneath it.
Ask an engineer where AI performance comes from and you will hear about process nodes, dataflow, HBM stacks and interconnect fabrics. Rarely about the wafer. Yet a … Read More
Power-SOI technology is rapidly emerging as a foundational platform for next-generation functional safety integrated circuits used in autonomous vehicles, industrial automation, humanoid robotics, and other mission-critical systems. The growing convergence of high-voltage power management and low-voltage digital… Read More
Recent independent teardown and technical analyses have confirmed that the 5G mmWave antenna module powering Apple’s latest iPhone 17 lineup relies on advanced SOITEC based Fully Depleted Silicon-On-Insulator (FD-SOI) substrate technology. The discovery highlights a significant architectural shift in high-frequency… Read More
Daniel is joined by Dr. Christophe Maleville, Chief Technology Officer and Senior Executive Vice-President of Soitec’s Innovation. He joined Soitec in 1993 and was a driving force behind the company’s joint research activities with CEA-Leti. For several years, he led new SOI process development, oversaw SOI technology transfer… Read More
Daniel is joined by Steve Babureck, executive vice president of strategy and president of Soitec USA. He joined the company in 2011 and held various positions including head of the finance department of the solar business in the United States, head of strategic marketing, and head of Group investor Relations in San Diego and Singapore.… Read More
The paper highlights how Fully Depleted Silicon-On-Insulator (FD-SOI) technology provides a robust defense against Laser Fault Injection (LFI), a precise, laboratory-grade attack method that can compromise cryptographic and safety-critical hardware. As vehicles become increasingly digital and connected, with dozens… Read More
As part of the broader Semicon West ecosystem in Phoenix, Arizona, Soitec, a global leader in engineered substrates for semiconductors, hosts an exclusive, invitation-style event titled Engineering the Future: Soitec Substrates Powering Technology Megatrends on Wednesday, October 8, 2025, from 2:30 PM to 6:00 PM MST.
Held… Read More
We are witnessing a significant revolution in automotive design. The software-defined vehicle is taking center stage as disruptive technologies are integrated into mass production. Areas such as autonomous driving, lighting, radar, and other camera-based sensors are all part of this revolution. AI is at the center of many… Read More
Engineered substrate technology is driving an evolution within the semiconductor industry. As Moore’s Law reaches its limits, the focus is shifting from traditional planar wafer scaling to innovative material engineering and 3D integration. Companies like Soitec, Intel and Samsung are pioneering this transition, unlocking… Read More
