Due to the positive development of the market capitalization, the Siltronic share is rejoining the MDAX index today. After several months in the SDAX, the Siltronic AG share is once again represented in the second most important index of the German stock exchange. Additionally, Siltronic shares will remain part of the TecDAX.
Throughout the year, Siltronic’s share price was negatively impacted by the market weakness in the semiconductor industry, which led to its descent to the SDAX in June 2023. Since then, the share price has steadily recovered, and the company’s market capitalization has increased significantly.
Dr. Michael Heckmeier, CEO of Siltronic, commented on this development: “The re-inclusion of Siltronic in the MDAX reflects investors’ confidence in our future prospects and our continued growth. This underscores the robust share price performance of recent months.”
Siltronic’s inclusion in the MDAX is part of Deutsche Börse AG’s regular quarterly review. The decision is based on the market capitalization of the freely tradable shares, i.e. the free float market capitalization.

Infineon Technologies AG announced its commitment to set a science-based target. By that Infineon expands its climate strategy even further. The company is very well on track towards CO2-neutrality by 2030, relating to its direct and indirect energy related emissions (Scope 1 and 2).
After having already reduced these emissions by 56.8 percent to date versus the base year of 2019, Infineon now sets itself even more ambitious targets by involving the supply chain (Scope 3) in the company’s climate protection efforts.
“Decarbonization is a guiding principle for Infineon. We have made great progress. With our commitment to set a science-based target, we are taking the next important step, adhering to the widely respected global standard for tackling climate change”, said Elke Reichart, Chief Digital Transformation Officer and responsible for Sustainability at Infineon. “We are actively inviting our suppliers to join us on our journey by setting their own carbon reduction targets. To truly address climate change, collaboration across the entire value chain, transparent and comprehensive data as well as global standards are foundational.”
Infineon has doubled its revenue since 2019 and halved its CO2 emissions (Scope 1 and 2) at the same time. The main drivers for lowering emissions are energy efficiency measures, comprehensive PFC abatement measures and switching its operations to renewable energy, which makes proportionally the largest contribution.
In 2023, Infineon reaches another key milestone in this respect. The two largest manufacturing sites in Asia – Kulim and Melaka in Malaysia – have now transitioned to green electricity, following the switch to renewables at its European and North American sites in 2021 and 2022 respectively.
The Science Based Targets initiative (SBTi) serves as a benchmark for ambitious climate action in the private sector. The initiative provides a clearly defined pathway for companies to reduce greenhouse gas (GHG) emissions. Targets are considered ‘science-based’ if they are in line with the latest climate science in order to meet the goals of the Paris Agreement – limiting global warming to well below 2°C above pre-industrial levels and pursuing efforts to limit warming to 1.5°C. SBTi is a partnership between the Carbon Disclosure Project (CDP), the United Nations Global Compact, World Resources Institute (WRI) and the World Wide Fund for Nature (WWF).
In 2020, Infineon had set its carbon neutrality target 2030 (Scope 1 and 2 emissions) already in line with science-based target requirements. With the expansion of its climate strategy to include Scope 3, Infineon is working closely together with supply chain partners and is putting special emphasis on further improvements in data availability and accuracy.

The paradigm shift towards offloading complexity to suppliers and adopting smaller IGBT modules is evident in various applications. In response to the global push for downsizing and integration, Infineon Technologies AG introduced the 4.5 kV XHP™ 3 IGBT modules that will fundamentally change the landscape for medium voltage drives (MVD) and transportation applications operating at 2000 to 3300 V AC in 2- and 3-level topologies.
Applications benefiting from the new devices include large conveyor belts, pumps, high-speed trains, locomotives, as well as commercial, construction and agricultural vehicles (CAV).
The XHP family comprises a 450 A dual IGBT module with TRENCHSTOP™ IGBT4 and an emitter-controlled diode, and a 450 A double diode module with emitter-controlled E4 Diode. Both modules feature improved isolation of 10.4 kV. Together, they help to simplify paralleling and downsizing without sacrificing efficiency.
Previously, complex busbars were required to parallelize switching modules, resulting in complicated design efforts and leakage inductance. The innovative design of the XHP family simplifies paralleling by conveniently placing the connections side by side. As a result, only a single straight busbar is required for paralleling.
The 4.5 kV XHP family also allows developers to reduce the number of units. Conventional IGBT solutions use multiple single switches and a double diode. With the new devices, however, designs can be reduced to two dual switches and a smaller double diode – a significant step forward in integrated drives.
The combination of the XHP 3 FF450R45T3E4_B5 dual switch and the DD450S45T3E4_B5 double diode enables significant cost savings and a smaller footprint. For example, Infineon’s previous IGBT solutions required four 140 x 190 mm² or 140 x 130 mm² switches and one 140 x 130 mm² double diode. With the new XHP family, the components can be reduced to two 140 x 100 mm² dual switches and a smaller 140 x 100 mm² double diode.
The IGBT modules FF450R45T3E4_B5 and DD450S45T3E4_B5 are available now. More information is available at www.infineon.com/XHP.

Aehr Test Systems announced it has received an initial customer order for a FOX-NP™ wafer level test and burn-in system and a FOX WaferPak™ Aligner to be used for gallium nitride (GaN) power devices. The customer is a leading global supplier of semiconductor devices used in electric vehicles and power infrastructure and adds another major customer to the list of companies using Aehr’s FOX products for wafer level test and burn-in of wide bandgap compound semiconductors. The FOX-NP system, including the FOX WaferPak Aligner, is scheduled to ship and be installed in the current fiscal quarter.
As Aehr’s first gallium nitride customer to order a system, this company selected Aehr due in part to its unique ability to offer a total solution that allows customers to apply thermal and electrical stress conditions to thousands of devices while still in wafer form. Aehr’s cutting-edge technology provides critical geolocation information across the wafer while inducing the extrinsic (early life) failures that would otherwise fail in the field without reducing the long-term reliability or life of the good devices.
Gayn Erickson, President and CEO of Aehr Test Systems, commented, “After seeing the positive results from their long and extensive evaluation of our FOX wafer level test systems for their silicon carbide devices, this customer decided to first move forward with our FOX-NP system to test their gallium nitride devices’ long-term reliability failure rates, as well as qualify the production extrinsic failure screening process for their devices in applications where safety, reliability, and/or security are critical.
A key consideration behind their decision is that the FOX-NP system is 100% compatible with the Aehr FOX-XP system that is targeted for high volume production and can support all the test modes needed for both gallium nitride and silicon carbide device testing and burn-in, including high-voltage testing of up to 2,000 volts with full wafer test without electrical arcing that can damage the wafer, which is a distinct advantage of our unique patented technology.
“Similar to silicon carbide, gallium nitride semiconductor MOSFETs are considered wide bandgap devices with much higher efficiencies in terms of power conversion than silicon, with gallium nitride being particularly good for lower power devices such as under 1000 watt power converters used in consumer devices such as cell phones, tablets, and laptop computers, as well as being targeted for automotive power converters for all the electrical systems in automobiles, whether electric vehicles or traditional gasoline automobiles. Gallium nitride MOSFETs are also believed by many industry analysts and technical communities to likely take over silicon as the power converter of choice for photovoltaic (solar panel) applications.
“Gallium nitride and silicon carbide devices both have excellent long-term intrinsic reliability, making them very good for automotive and industrial applications. But both also experience higher than acceptable early life or extrinsic failures related to the material and processing steps. Gallium nitride and silicon carbide semiconductor suppliers can add a special stress or screening test known as burn-in on 100% of the devices to identify and remove these early life failures so that they can meet the end customers’ target reliability needs. This 100% burn-in requirement is not unique to these devices, as it is also the case with microprocessors and microcontrollers, dynamic random-access memories (DRAM), flash non-volatile memories, as well as many sensors used in automotive and other industrial applications.”
Aehr enables its customers to cost-effectively implement the needed testing and qualification process for semiconductor devices that experience early life failures by not only applying the electrical stress condition to every device on the wafer but by also testing up to 18 wafers at a time using the FOX-XP production test and burn in system. These electrical tests are done with up to thousands of precise calibrated electrical source and measurement instruments per wafer. These tests are done while maintaining the temperature at an accurately programmed thermal temperature across each of the wafers using a direct conduction thermal transfer via a proprietary patented precision thermal chuck per wafer.
The FOX-NP compliments Aehr’s production FOX-XP system by using the exact same test ‘Blades’ that are in the FOX-XP to allow 100% correlation between the results on the FOX-NP to the FOX-XP.
The FOX-XP and FOX-NP systems, available with multiple WaferPak Contactors (full wafer test) or multiple DiePakTM Carriers (singulated die/module test) configurations, are capable of functional test and burn-in/cycling of devices such as silicon carbide and gallium nitride power semiconductors, silicon photonics as well as other optical devices, 2D and 3D sensors, flash memories, magnetic sensors, microcontrollers, and other leading-edge ICs in either wafer form factor, before they are assembled into single or multi-die stacked packages, or in singulated die or module form factor.
