    3 Min Read

    Soitec announced its revenue for the second quarter of fiscal year 2024 and its results for the first half of fiscal year 2024 (ended on September 30th, 2023). The financial statements were approved by the Board of Directors during its meeting today.

    • Q2’24 revenue reached €245m, down 7% at constant exchange rates and perimeter compared to Q2’23
    • H1’24 revenue at €401m, down 15% both at constant exchange rates and perimeter and on a reported basis compared with H1’23 – in line with guidance
    • H1’24 EBITDA margin stood at the robust level of 33% of revenue while the Company maintained significant investment in R&D
    • Anticipated return to a slight year-on-year organic growth in H2’24, leading to a moderate downward revision of FY24 outlook: mid-single digit decline in FY’24 revenue expected at constant exchange rate and EBITDA1 margin2 anticipated around 35%

    Pierre Barnabé, Soitec’s CEO, commented: “With a sequential growth of over 50% compared to the first quarter, our second-quarter revenue rebounded significantly, as we had anticipated. This was particularly the case in Mobile Communications as the inventory correction across the smartphone value chain eased. We continue to leverage strong demand in Automotive to deploy our SmartSiC™roadmap and we continue to progress actively with several customers.

    Overall, our first half revenue is in line with our expectations. We have maintained strong profitability and a solid financial position, while continuing to invest in R&D and industrial capacity, as well as building inventories to prepare for H2’24.

    Looking ahead, we maintain our growth perspectives for the second part of the fiscal year. We note however that the absorption of RF-SOI inventories at our customers level will last longer than anticipated. At the same time, we continue to expect sustained demand in Automotive & Industrial as well as in Smart Devices. Consequently, we now anticipate a full-fiscal-year revenue decline of around mid-single digit percentage, and an EBITDA margin of around 35%. After this transition year, we will resume our growth trajectory” added Pierre Barnabé.

    FY’24 outlook

    Soitec confirms growth recovery in the second half of FY’24. Against the backdrop of a weaker-than-expected smartphone market, the extent of the inventory correction at our customers level is greater than anticipated. We confirm strong traction for our Automotive & Industrial and Smart Devices divisions. We now anticipate our FY’24 revenue to slightly decline, by around a mid-single digit percentage, compared to FY’23, at constant exchange rates and perimeter.

    As a result, FY’24 EBITDA margin is now expected to be around 35% of revenue. The Group will continue to implement cost control measures, while further investing significantly in R&D.

    FY’24 Capital expenditure is expected to be around 290 million Euros in order to support growth beyond FY’24. Soitec’s growth outlook remain very strong: while the SOI content within end devices continues to increase, the ongoing penetration of the Group’s products across its three end markets and the successful deployment of its expansion into Compound Semiconductors with POI and SmartSiC™ becoming new significant growth drivers in the future.

  • Rigaku SE and Fraunhofer IISB Unique X-ray Topography Based Defect Characterization for SiC Wafers Honored with Georg Waeber Innovation Award 2023

    Rigaku SE and Fraunhofer IISB Unique X-ray Topography Based Defect Characterization for SiC Wafers Honored with Georg Waeber Innovation Award 2023

    4 Min Read

    A cross-organizational team from Rigaku SE and Fraunhofer IISB has established a new semicon-ductor material characterization method in their jointly operated Center of Expertise for X-ray Topography in Erlangen, Germany. They succeeded not only in developing an industry-ready X-ray topography system, but also in employing defect detection and quantification algorithms, achieving a worldwide unique material characterization method for silicon carbide (SiC) wafers.

    SiC is an excellent semiconductor for application areas like electric mobility and transportation, sustainable energy supply, industrial infrastructure up to sensors and quantum technologies even under harsh operating conditions.

    As representatives for the whole research team, Dr. Kranert and Dr. Reimann from Fraunhofer IISB and Dr. Hippler, Managing Director Rigaku Europe SE, have won the Georg Waeber Innovation Award 2023 from the Förderkreis für die Mikroelektronik e.V. (Microelectronics Promotion Society).

    Pioneering holistic material defect characterization with X-ray topography

    In 2021, Rigaku SE and Fraunhofer IISB have founded the Center of Expertise for X-ray Topography, a joint lab that is located at the IISB’s headquarters in Erlangen, Germany. Here, the cross-organizational team has now developed a new metrology that is non-destructive, robust, reliable, high-throughput and therefore capable of swiftly detecting all relevant crystallographic defects in SiC substrates.

    For the first time worldwirde, this innovation realized the holistic approach of setting up the measurement device, i.e., the X-ray topography (XRT) tool as well as formulating appropriate measurement and analysis routines that specifically meet the industry’s demands for speed, reliability, and accuracy. The development process was supported by rigorous scientific validation of the results, a crucial factor for the acceptance of a new approach in the industry.

    Until now, no such industry-ready metrology existed for the early stages of SiC power electronics manufacturing, especially at substrate or crystal (commonly referred to as the “puck”) level. This breakthrough in SiC substrate inspection makes it no longer necessary to, e.g., destructively defect etch and discard semiconductor substrates for characterization, as is currently often the case. In consequence, the developed XRT metrology is superior to these existing substrate characterization methods employed in the industry, ultimately leading to substantial cost savings.

    Effectively, this technology, developed in Germany, provides everything needed to become the industry standard for specifying and controlling substrate quality in production as well as for R&D substrate and device manufacturers worldwide. The success of this joint innovation is vividly illustrated by the new business, which Rigaku has successfully established in less than two years. Now, the Japan-based company is the world’s leading supplier of XRT tools for SiC substrate and device manufacturing. 

    The innovative metrology approach has been driven significantly by Dr. Michael Hippler, Managing Director of Rigaku Europe SE, and Dr. Christian Kranert with Dr. Christian Reimann, both group managers in the Fraunhofer IISB’s Materials department. Hence the scientists were selected for the Georg Waeber Innovation Award 2023 by the Förderkreis für die Mikroelektronik e.V. (Microelectronics Promotion Society).

    The Förderkreis is an association of industry companies, two Fraunhofer institutes, four chairs of the University of Erlangen-Nuremberg and the Nuremberg Chamber of Commerce and Industry. The main objective is to foster a smooth exchange between science and industry, which is manifested in the Georg Waeber Innovation Award. The award is presented annually for outstanding scientific achievements and places a strong emphasis on the advancement of knowledge in microelectronics and its practical application in the industry. On October 25, 2023, Dr. Hippler, Dr. Reimann and Dr. Kranert received the award during a ceremony at Fraunhofer IISB in Erlangen.

    Paving the way for the next generation of SiC power electronics

    SiC semiconductor devices play a pivotal role in the power electronics industry. As a replacement for conventional silicon-based power electronics, SiC has the potential to enhance energy efficiency while reducing system costs. It is relevant across various application areas from electric mobility and transportation, sustainable energy supply, industrial infrastructure up to sensors and quantum technologies even under harsh operating conditions.

    Consequently, processing low-cost, energy-efficient, and highly reliable SiC power devices is a critical endeavor with the worldwide electrification trend. The production capacities for SiC wafers experience significant growth, which goes hand in hand with an increasing demand for wafer inspection and metrology within the SiC industry. In particular, manufacturers of substrates and power devices require precice information regarding the quality of substrates in terms of crystallographic defects, their distribution across the entire wafer area, and absolute quantities.
