Efficient Power Conversion Corp (“EPC”) announced that the China National Intellectual Property Administration (“CNIPA”) has validated the claims of EPC patent titled “Compensated gate MISFET and method for fabricating the same” (Chinese Patent No. ZL201080015425.X) for enhancement-mode GaN semiconductor devices.
The decision on April 30, 2024 follows an April 2, 2024 announcement from the CNIPA that confirmed the validity of key claims of EPC’s Chinese patent titled “Enhancement mode GaN HEMT device and method for fabricating the same” (Chinese Patent No. ZL201080015388.2). Both EPC patents were challenged by Innoscience (Suzhou) Technology Co., Ltd. (“Innoscience”).
Compared with traditional silicon-based power devices, GaN technology represents a transformational leap with higher efficiency, faster switching speeds and smaller size. GaN devices are used in artificial intelligence servers, self-driving vehicles, next-generation rapid chargers, drones, e-bikes, and humanoid robots, among other applications. Chinese Patent No. ZL201080015425.X covers the fundamental design and configuration of EPC’s proprietary enhancement mode GaN field effect transistors (FETs) with reduced gate leakage. Most industry participants employ the GaN gate technology covered by this patent.
“These are two of the foundational patents supporting our broad portfolio of innovations, and we are pleased that the CNIPA has again confirmed the validity of our valuable intellectual property,” said Alex Lidow, CEO and Co-founder of EPC. “Quick, fair and efficient decisions such as these reinforce the confidence in legal systems that companies need to operate globally.”
In May 2023, EPC filed complaints in the U.S. federal court in Los Angeles and in the U.S. International Trade Commission, asserting that Innoscience (Zhuhai) Technology Co., Ltd. and its affiliates infringe patents of its foundational patent portfolio, which include the U.S. counterparts of EPC’s Chinese Patent Nos. ZL201080015425.X and ZL201080015388.2. In response, Innoscience had petitioned the CNIPA to invalidate the two Chinese patents.

Semikron Danfoss to Build Semiconductor Processing to Packaging Center at SUNY Polytechnic Institute
3 Min ReadSemikron Danfoss announced its collaboration with SUNY Polytechnic Institute and other industry partners to build a Semiconductor Processing to Packaging Center that will focus on research, education and training. The facility will be established at the Semikron Danfoss office in Utica, located in the Quad C building on the SUNY Poly campus and will train 100-150 students per year in semiconductor processing, packaging and testing capabilities.
The official announcement came on Tuesday at the site of the future facility at a ceremony attended by over 100 people, including New York’s Lt. Gov. Antonio Delgado and other state and local business leaders and elected officials. “The cornerstone of our regional economic development process is collaborative, community-led projects that will build a stronger future for New Yorkers statewide,” said Delgado.
The center will be funded in part with the $4 million Empire State Development grant, announced Tuesday, as well as a larger economic development package announced by New York Governor Kathy Hochul for SUNY Poly last fall. In addition to supplying space for two classrooms and a 5,000 square-foot clean room, Danfoss will provide multiple pieces of equipment used in the semiconductor manufacturing process.
The Center will allow for both silicon device processing as well as SiC, GaN, AlN and their alloys, and Ga2O3 device processing for power electronics, optoelectronics and clean energy applications as well as their unique packaging needs.
It is anticipated that the students will be both traditional and non-traditional students, seeking either degrees or certificates. The goal of the Center is to increase graduates across advanced manufacturing disciplines by 10 percent in the next four years. The Center’s curriculum will offer several workforce development training and upskilling pathways for industry partners and their employees as well as those seeking to gain entrance into the workforce.
“The creation of a single center covering research, education and training capabilities across semiconductor processing to packaging will provide students and the future workforce with both the deep theoretical knowledge as well as the hands-on experience needed to fully understand the workflow and attention to detail needed to produce devices with the required yield and performance functionality,” said Michael Carpenter, Ph.D., Interim Dean of SUNY Poly’s College of Engineering and Associate Provost for Research. “We are looking forward to working with Danfoss and our other industry and community partners on this initiative.”
“Partnering with educational and community organizations in the communities where we operate is an important focus of Danfoss’ mission,” said Michael Godsen, general manager of Semikron Danfoss in the U.S. “We are excited to work with SUNY Poly to develop a skilled workforce in the semiconductor industry.”

Siltronic AG continued to be affected by weak demand in Q1 2024 due to increased customer inventory levels, with sales declining nearly 4 percent compared to Q4 2023, primarily due to product mix shifts.
“The start of the year continues to be characterized by weak demand due to increased inventories at our customers. It is still not possible to predict when inventories will return to a normal level. Therefore, 2024 will probably be a transition year on the way to profitable growth,” comments Dr. Michael Heckmeier, CEO of Siltronic AG on the development.
Business Development in Q1 2024
Siltronic generated sales of EUR 343.5 million in Q1 2024, which corresponds to a decrease of 3.7 percent compared to Q4 2023. This development is in line with expectations. While the wafer area sold and sales prices remained nearly stable compared to the previous quarter, the product mix in particular had a slightly negative impact. The Euro/US dollar exchange rate, which averaged 1.09 in Q1 2024 (Q4 2023: 1.08), also impacted sales slightly on a quarterly basis.
Cost of sales decreased by 1.4 percent compared to the previous quarter and therefore could not be reduced at the same level as sales.
As a result, the gross profit in Q1 2024 decreased by EUR 9.1 million compared to the previous quarter. The gross margin decreased from 22.2 percent (Q4 2023) to 20.4 percent (Q1 2024).
The decrease in gross profit was largely offset by positive FX effects and lower selling, administration, and research and development expenses. The FX effects reported in the balance of other operating income and expenses amounted to EUR 5.4 million after EUR -0.8 million in Q4 2023.
EBITDA in Q1 2024 (EUR 90.8 million) was therefore on par with the previous quarter (Q4 2023: EUR 91.1 million). Due to the decline in sales, the EBITDA margin improved from 25.5 percent to 26.4 percent.
EBIT amounted to EUR 36.0 million in Q1 2024 compared to EUR 36.8 million in Q4 2023. The marginal decline is mainly due to a higher depreciation.
Despite continued weak demand, a EUR 27.7 million result for the period was achieved after EUR 32.3 million in the previous quarter. Of this amount, EUR 25.7 million is attributable to the shareholders of Siltronic AG, resulting in earnings per share of EUR 0.86.
Development of equity, net cash flow and net financial assets
With an equity of EUR 2,152.9 million as of March 31, 2024 and an equity ratio of 46.5 percent, Siltronic continues to have a solid balance sheet quality (December 31, 2023: 46.6 percent).
Loan liabilities increased by EUR 53.4 million, mainly due to the partial draw down of a loan. In addition, other provisions and liabilities increased by EUR 31.4 million, mainly due to an investment grant received.
The decrease in cash flow from operating activities compared to the previous quarter is mainly due to reporting date effects in the inflow of trade receivables. In Q4 2023, payments were received from customers shortly before the reporting date, and in Q1 2024 shortly after the reporting date.
In the quarter under review, Siltronic made net payments of EUR 198.7 million for capex including intangible assets. Due to the high capex at the end of 2023, some of which was not due for payment until 2024, capex payments significantly exceeded additions to the balance sheet in the quarter under review. The payments and balance sheet additions were mainly related to the new fab in Singapore.
Due to the change in working capital and the continued high level of investments, both the free cash flow of EUR -137.2 million and the net cash flow of EUR -158.4 million were negative in Q1 2024. As a result, cash and cash equivalents and financial investments decreased by EUR 88.9 million, while loan liabilities increased at the same time. Accordingly, net financial debt increased from EUR 355.7 million at the end of 2023 to EUR 501.0 million as of March 31, 2024.
Outlook: Mid-term targets for 2028 unchanged, 2024 will be a transition year
Driven by several megatrends, Siltronic expects a significant increase in demand in the medium and long term. However, the start to the 2024 financial year was subdued. Although demand for wafers is increasing in the end markets, Siltronic continues to face weak demand in the coming quarters. This is due to higher customer inventories and the associated further postponement of delivery volumes, which will now primarily affect the second half of the year. Customers’ persistently high inventories are recovering slower than originally expected. As a result, the impact of these elevated inventories is expected to be felt throughout 2024, although visibility remains limited.
In an ad hoc announcement on April 26, 2024, Siltronic therefore adjusted its forecast and expects Group sales to be roughly 10 percent below the previous year. This is mainly due to lower volumes and both slightly negative FX- (EUR/USD 1.10) and price effects. The EBITDA margin is forecast to be between 21 and 25 percent. Capital expenditure will decrease compared to the previous guidance and is expected to be slightly below EUR 550 million. Depreciation and amortization is expected to be below EUR 300 million.
Klaus Buchwald to be appointed Chief Operating Officer as early as June 1, 2024
Klaus Buchwald will take up his position as a new member of the Executive Board and Chief Operating Officer (COO) of Siltronic AG on June 1, 2024, two months earlier than originally announced. He will be responsible for Operations and Supply Chain, Engineering as well as IT.

To provide higher efficiency and power density for telecom, industrial, and computing applications, Vishay Intertechnology, Inc. introduced its first fourth-generation 600 V E Series power MOSFET in the new PowerPAK® 8 x 8LR package.
Compared to previous-generation devices, the Vishay Siliconix n-channel SiHR080N60E slashes on-resistance by 27 % and resistance times gate charge, a key figure of merit (FOM) for 600 V MOSFETs used in power conversion applications, by 60 % while providing higher current in a smaller footprint than devices in the D²PAK package.
Vishay offers a broad line of MOSFET technologies that support all stages of the power conversion process, from high voltage inputs to the low voltage outputs required to power the latest high tech equipment. With the SiHR080N60E and other devices in the fourth-generation 600 V E Series family, the company is addressing the need for efficiency and power density improvements in two of the first stages of the power system architecture — power factor correction (PFC) and subsequent DC/DC converter blocks.
Typical applications will include servers, edge computing, super computers, and data storage; UPS; high intensity discharge (HID) lamps and fluorescent ballast lighting; telecom SMPS; solar inverters; welding equipment; induction heating; motor drives; and battery chargers.
Measuring 10.42 mm by 8 mm by 1.65 mm, the SiHR080N60E’s compact PowerPAK 8 x 8LR package features a 50.8 % smaller footprint than the D²PAK while offering a 66 % lower height. Due to its top-side cooling, the package delivers excellent thermal capability, with an extremely low junction to case (drain) thermal resistance of 0.25 °C/W.
This allows for 46 % higher current than the D²PAK at the same on-resistance level, enabling dramatically higher power density. In addition, the package’s gullwing leads provide excellent temperature cycle capability.
Built on Vishay’s latest energy-efficient E Series superjunction technology, the SiHR080N60E features low typical on-resistance of 0.074 Ω at 10 V and ultra low gate charge down to 42 nC. The resulting FOM is an industry-low 3.1 Ω*nC, which translates into reduced conduction and switching losses to save energy and increase efficiency in power systems > 2 kW.
For improved switching performance in hard-switched topologies such as PFC, half-bridge, and two-switch forward designs, the MOSFET released today provides low typical effective output capacitances Co(er) and Co(tr) of 79 pF and 499 pF, respectively. The package also provides a Kelvin connection for improved switching efficiency.
The device is RoHS-compliant and halogen-free, and it is designed to withstand overvoltage transients in avalanche mode with guaranteed limits through 100 % UIS testing.
