As part of their strategic partnership announced earlier this year, ZF Friedrichshafen AG, a leading global technology company of next generation mobility, and Wolfspeed Inc, the global leader in Silicon Carbide technology, announced their plans to establish a joint European R&D center for Silicon Carbide power electronics in the Nuremberg Metropolitan Region.
The new joint research facility is supported by the German federal government and the regional government of Bavaria. Like the planned Wolfspeed Silicon Carbide chip factory in Ensdorf, Saarland, funding for the new center is subject to approval by the European Commission under the EU’s Important Project of Common European Interest (IPCEI) scheme, as well as antitrust authorities. The aim is to develop the two facilities to become the cornerstone of a new European Silicon Carbide technology network.
Construction will begin after IPCEI funding approval has been secured for both projects, which is expected later this year. The goal of the collaboration is to develop breakthrough innovations for Silicon Carbide systems, products, and applications, covering the full value chain from module to complete systems and thus reducing time-to-market significantly. The joint research center will target requirements in all mobility segments including consumer, commercial, agricultural, and industrial vehicles, as well as in the industrial and renewable energy markets. The collaboration aims to drive improvements such as higher efficiency, increased power density and higher performance of electrification solutions. Wolfspeed’s Silicon Carbide expertise and ZF’s access to all mobility segments allows for a fast and seamless transition of new technologies.
ZF and Wolfspeed are partnering with other leading organizations from the scientific and industrial communities to establish a comprehensive European Silicon Carbide technology network. To this end, ZF will use its membership in the European Center of Power Electronics (ECPE) and share key research results at the European level. Over time, the research center is planned to develop into an electronics and semiconductor campus.
“The research center is of outstanding importance for the energy and mobility transition in the EU and supports the strategic goals of Europe,” says Dr Holger Klein, CEO of ZF. “In addition, optimizing Silicon Carbide technology advances industrial transformation and strengthens the independence of European supply chains.”
“This research facility further strengthens our partnership with ZF and underlines our long-term commitment to turn our unique know-how from more than 35 years of experience in Silicon Carbide power electronics into state-of-the-art solutions for our industry partners,” comments Gregg Lowe, CEO of Wolfspeed Inc.
The strategic partnership links ZF, one of the world’s leading suppliers of electric drives, with Wolfspeed, the world’s most recognized specialist in Silicon Carbide technology. “This connection is unique and will lead to enormous advances in Silicon Carbide-based electrical systems and electric drives,” says ZF Board of Management member Stephan von Schuckmann. “This is made possible by the close networking of the research center and production, because fundamentally redesigned Silicon Carbide chips also require new production processes.”

Magnachip Semiconductor Corporation (“Magnachip” or “Company”) announced that the Company has released a new family of 600V Super Junction Metal Oxide Semiconductor Field Effect Transistors (SJ MOSFETs) consisting of nine distinct products featuring proprietary design technology.
Magnachip’s proprietary design provides specific on-resistance (RSP) reduction of about 10%, and this result was achieved while maintaining the same cell-pitches of previous generation MOSFETs.
In addition, the new product family of 600V SJ MOSFETs is equipped with a fast recovery body diode. This diode technology significantly enhances system efficiency with reduced reverse recovery time (trr) and switching loss. Therefore, the figure of merit to evaluate general performance of MOSFETs was improved by more than 10% compared to the previous generation. As such, these 600V SJ MOSFETs can be used widely in industrial applications, such as solar inverters, energy storage systems, uninterruptible power supply systems, and a variety of electronics.
Among these new MOSFETs, the MMQ60R044RFTH product offers an exceptionally low RDS(on) of 44mΩ, making it an optimal choice for electric vehicle chargers and servers. Omdia, a global market research firm, estimates that the compound annual growth rates of Si MOSFET markets for hybrid & electric vehicles and servers will be 11% and 7%, respectively, from 2023 to 2026.
“Now that we have introduced these 600V SJ MOSFET products, we are aiming to unveil new 650V and 700V SJ MOSFET products with fast recovery body diode in the second half of 2023,” said YJ Kim, CEO of Magnachip. “These new MOSFETs represent a notable achievement for the Company, and we will build upon this success to deliver next-generation power solutions for rapidly changing market requirements and customer expectations.”

Henkel announced the addition of Loctite Ablestik ABP 8068TI to its growing portfolio of high thermal die attach adhesives. With 165 W/m-K thermal conductivity, the new pressure-less sintering die attach paste boasts the highest thermal capability in the company’s semiconductor packaging portfolio, meeting performance requirements for high-reliability automotive and industrial power discrete semiconductor devices.
“High voltage applications like those found in automotive ADAS systems, EVs, industrial motor controls, and high-efficiency power supplies require superior electrical and thermal performance,” says Henkel’s Global Market Segment Head for Semiconductor Packaging Materials, Ramachandran Trichur. “Currently, the only viable die attach alternative to Pb solder – which will soon be phased out and cannot meet certain thermal demands – is sintered silver (Ag). Henkel pioneered pressure-less sintering die attach, allowing the use of standard, low-stress processing, and we have now formulated our fourth and highest thermal conductivity material to date, which tackles the stringent thermal and electrical requirements of next-generation power packages.”
Henkel’s newest pressure-less sintering die attach formulation meets multiple metrics for power semiconductors like MOSFETs, which are increasingly incorporating silicon carbide (SiC) and gallium nitride (GaN) materials as alternatives to silicon (Si) for improved efficiency. Loctite Ablestik ABP 8068TI is compatible with traditional Si and newer wide-bandgap semiconductors, among other power discrete devices. The 165 W/m-K ultra-high thermal conductivity die attach adhesive has demonstrated excellent sintering properties with good adhesion on copper (Cu), pre-plated frames (PPF), silver (Ag), and gold (Au) lead frames, robust electrical conductivity and stable RDS(on) after 1,000 hours of thermal cycling, and MSL 3 reliability.
Recommended for dies measuring 3.0 mm x 3.0 mm or smaller, Loctite Ablestik ABP 8068TI fully cures at 175° C or above to form a rigid sintered Ag network in the bulk epoxy and at the interface. Because pressure-less sintering is a drop-in replacement for standard die attach, high pressure is not required to achieve this robust structure, eliminating stress on thin die. Workability of the material is also notable at three hours of void-free open time and 24 hours of stage time with no degradation in shear strength.
As Trichur concludes, the power device market will only accelerate in application uses and performance requirements, making high-capability, high thermal die attach solutions an operational necessity: “There is an increased demand for power devices across market sectors, including automotive, industrial power storage and conversion, and aerospace, to name a few. For power semiconductors, sintered die attach is the prevailing and most reliable solution to deliver the die attach strength, integrity, and thermal and electrical conductivity required. Loctite Ablestik ABP 8068TI provides all this in a formula that enables simple processing to protect thinner, more complex dies.”
