Overview

Soitec is a global leader in the design and manufacturing of engineered semiconductor materials. The company specializes in advanced substrates that significantly enhance the performance, energy efficiency, and integration capability of chips used in smartphones, automotive systems, cloud computing, consumer electronics, and industrial applications.

Headquartered in Bernin, France, Soitec is best known for pioneering silicon-on-insulator (SOI) technology and developing breakthrough engineered wafers that serve as foundational building blocks for next-generation semiconductors.

History and Foundation

Soitec was founded in 1992 by two physicists with a vision to commercialize silicon-on-insulator (SOI) technology, which originated in French public research labs. The company was established near Grenoble, France, in the heart of Europe’s semiconductor innovation ecosystem.

Since its founding, Soitec has grown into a global materials technology leader, expanding its portfolio from SOI into a range of advanced substrates for RF, power, photonics, and quantum applications. It has also established international manufacturing and R&D operations to meet the increasing global demand for specialized semiconductor materials.

Core Technologies and Products

1. Silicon-on-Insulator (SOI) Substrates

SOI wafers are the company’s flagship product, used to improve chip performance while reducing power consumption and parasitic capacitance. Soitec’s proprietary Smart Cut™ technology enables precise layer transfer for the production of high-quality SOI substrates.

Types of SOI wafers include:

• RF-SOI: Optimized for radio frequency and 5G front-end modules.

• Power-SOI: Designed for automotive and industrial power ICs.

• FD-SOI (Fully Depleted SOI): Used in low-power, high-performance computing and IoT applications.

2. Piezoelectric-on-Insulator (POI)

Used for high-frequency acoustic filters (e.g., 5G RF filters), POI substrates combine a piezoelectric material layer with insulating properties for better acoustic performance and signal isolation.

3. Silicon Photonics Substrates

Engineered wafers tailored for silicon photonics applications, enabling the integration of optical interconnects with standard CMOS logic for data center, AI, and telecom systems.

4. Gallium Nitride (GaN) and Power Substrates

Substrates for wide-bandgap power devices to support fast-switching, high-efficiency power electronics in automotive, datacenter, and renewable energy markets.

5. Quantum and Emerging Substrates

Development of advanced substrates for quantum computing, cryogenic operation, and ultra-low power sensing applications.
