Texas Instruments (TI) announced it has begun production of gallium nitride (GaN)-based power semiconductors at its factory in Aizu, Japan. Coupled with its existing GaN manufacturing in Dallas, Texas, TI will now internally manufacture four times more GaN-based power semiconductors, as Aizu ramps to production.
“Building on more than a decade of expertise in GaN chip design and manufacturing, we have successfully qualified our 200mm GaN technology – the most scalable and cost-competitive way to manufacture GaN today – to start mass production in Aizu,” said Mohammad Yunus, TI’s senior vice president of Technology and Manufacturing. “This milestone enables us to manufacture more of our GaN chips internally as we grow our internal manufacturing to more than 95% by 2030, while also sourcing from multiple TI locations, ensuring a reliable supply of our entire GaN portfolio of high-power, energy-efficient semiconductors.”
An alternative to silicon, GaN is a semiconductor material that offers benefits in energy-efficiency, switching speed, power solution size and weight, overall system cost, and performance under high temperatures and high-voltage conditions. GaN chips provide more power density, or power in smaller spaces, enabling applications such as power adapters for laptops and mobile phones, or smaller, more energy-efficient motors for heating and air conditioning systems and home appliances.
Today, TI offers the widest portfolio of integrated GaN-based power semiconductors, ranging from low- to high-voltage, to enable the most energy-efficient, reliable and power-dense electronics.
“With GaN, TI can deliver more power, more efficiently in a compact space, which is the primary market need driving innovation for many of our customers,” said Kannan Soundarapandian, vice president of High-Voltage Power at TI. “As designers of systems such as server power, solar energy generation and AC/DC adapters face challenges to reduce power consumption and enhance energy efficiency, they are increasingly demanding a reliable supply of TI’s high-performance GaN-based chips. TI’s product portfolio of integrated GaN power stages enables customers to achieve higher power density, improved ease of use and lower system cost.”
Further, with the company’s proprietary GaN-on-silicon process, more than 80 million hours of reliability testing, and integrated protection features, TI GaN chips are designed to keep high-voltage systems safe.
Using the most advanced equipment available for GaN chip manufacturing today, TI’s new capacity enables increased product performance and manufacturing process efficiency, as well as a cost advantage. Also, the more advanced, efficient tools used in TI’s expanded GaN manufacturing can produce smaller chips, packing even more power. This design innovation can be manufactured using less water, energy and raw materials, and end products that use GaN chips enjoy these same environmental benefits.
The performance benefits of TI’s added GaN manufacturing also enable the company to scale its GaN chips to higher voltages, starting with 900V and increasing to higher voltages over time, furthering power-efficiency and size innovations for applications like robotics, renewable energy and server power supplies.
In addition, TI’s expanded investment includes a successful pilot earlier this year for development of GaN manufacturing processes on 300mm wafers. Further, TI’s expanded GaN manufacturing processes are fully transferable to 300mm technology, positioning the company to readily scale to customer needs and move to 300mm in the future.
Expanding supply and innovation in GaN technology is the latest example of TI’s commitment to responsible, sustainable manufacturing. TI has committed to use 100% renewable electricity in its U.S. operations by 2027, and worldwide by 2030.

As expected, the business performance of Siltronic AG in Q3 2024 was characterized by subdued demand from the semiconductor industry.
“In a persistently challenging market environment, we have delivered solid quarterly results. Consequently, we can confirm our guidance for the full year 2024. However, it remains uncertain when chip manufacturers’ inventories will return to normal levels,” commented Dr. Michael Heckmeier, CEO of Siltronic AG on the developments.
Siltronic generated sales of EUR 357.3 million in Q3 2024, an increase of 1.7 percent compared to the previous quarter (Q2 2024: EUR 351.3 million). This is due to an increase in wafer area sold, which was partially offset by opposing product mix effects. After nine months, the company reported sales of EUR 1,052.2 million, a decrease of 9.1 percent year-on-year (Q1-Q3 2023: EUR 1,157.2 million). This was mainly due to the lower wafer area sold. In addition, product mix-, price- and FX effects also had a slightly negative impact.
Cost of sales increased by 2.6 percent in Q3 2024 compared to the previous quarter, mainly due to higher wafer area sold and a moderate increase in depreciation. For the first nine months of 2024, cost of sales decreased by 2.5 percent compared to the same period in 2023. The disproportionate decline compared to sales is primarily due to a reduced dilution of fixed costs and higher depreciation.
As a result, the gross profit fell by EUR 1.4 million compared to the previous quarter and from January to September 2024 by EUR 83.1 million compared to the previous year. The gross margin fell from 25.3 percent to 20.0 percent year-on-year.
EBITDA in Q3 was EUR 89.4 million and thus on the level of the previous quarter (Q2 2024: EUR 90.6 million). The EBITDA margin remained at a solid level of 25.0 percent (Q2 2024: 25.8 percent). After nine months, Siltronic reported an EBITDA of EUR 270.7 million (Q1-Q3 2023: EUR 342.8 million) and an EBITDA margin of 25.7 percent (Q1-Q3 2023: 29.6 percent).
Due to the lower EBITDA and higher depreciation, EBIT amounted to EUR 28.9 million in Q3 (Q2 2024: EUR 33.0 million) and to EUR 97.8 million after the first nine months (Q1-Q3 2023: EUR 194.5 million). Net profit for the quarter was EUR 18.8 million (Q2 2024: EUR 22.4 million) and earnings per share were EUR 0.60 (Q2 2024: EUR 0.73). Net income for the period from January to September was EUR 68.8 million (Q1-Q3 2023: EUR 169.0 million) and earnings per share of EUR 2.19 after EUR 5.13 in the same period of the previous year.
With an equity ratio of 47.1 percent as of September 30, 2024 (December 31, 2023: 46.6 percent), Siltronic continues to maintain a good balance sheet quality. Loan liabilities increased mainly due to the partial draw of a loan. Additionally a promissory note loan was successfully placed in September and paid out in early October. At roughly EUR 370 million, the original issue volume was significantly exceeded.
“We are pleased with the high level of interest in this transaction. The strong demand is a demonstration of the promissory note loan investors’ trust in the company,” adds Claudia Schmitt, CFO of Siltronic AG.
Cash flow from operating activities for the period January to September 2024 decreased by EUR 83.3 million compared to the previous year. This was mainly due to the lower EBITDA and the change in prepayments. In the same period of the previous year, there was a significant net inflow, while in the first nine months of the financial year there was a net outflow of prepayments.
Despite a noticable reduction in capex during the year, cash outflows for capex remained at a high level of EUR 565.1 million, mainly due to the construction of the new 300 mm fab in Singapore. Accordingly, net cash flow, which excludes cash inflows and outflows from prepayments, was negative as expected at EUR -317.7 million (Q1-Q3 2023: EUR -631.3 million).
As a result, cash and cash equivalents and financial investments decreased by EUR 168.4 million to EUR 290.7 million in the first nine months of 2024. Siltronic thus reported net financial debt of EUR 739.1 million at the end of September 2024.
As already communicated in the half-year report 2024, Siltronic AG’s Executive Board expects sales to be in the high single-digit percentage range below the previous year. This is primarily due to the lower wafer area sold, as well as each slightly negative FX rate (EUR/USD 1.10), price- and product mix effects.
The customer qualifications that are decisive for the start of depreciation of the new fab in Singapore have been delayed from the fourth quarter of 2024 into next year. As a result, depreciation of the new fab and other ramp costs that impact earnings will occur over the course of 2025. Accordingly, the full-year EBITDA margin guidance is adjusted to 24 to 26 percent. Depreciation and amortization for 2024 will therefore be lower and is expected to be between EUR 230 million and EUR 250 million. Capex including intangible assets remains unchanged and will be in the range of EUR 500 million to EUR 530 million.
Despite the challenging market environment, the company anticipates a significant growth potential in the medium and long term. Key drivers of this growth are megatrends such as Artificial Intelligence, Digitization, and Electromobility. With its investments in expanding production capacity and improving the product mix, Siltronic is well-positioned to profitably support this growth.

Many industrial applications today are transitioning to higher power levels with minimized power losses, which can be achieved through increased DC link voltage. Infineon Technologies AG addresses this challenge by introducing the CoolSiC™ Schottky diode 2000 V G5, the first discrete silicon carbide diode on the market with a breakdown voltage of 2000 V. The product family is suitable for applications with DC link voltages up to 1500 VDC and offers current ratings from 10 to 80 A. This makes it ideal for higher DC link voltage applications such as in solar and EV charging applications.
The product family comes in a TO-247PLUS-4-HCC package, with 14 mm creepage and 5.4 mm clearance distance. This, together with a current rating of up to 80 A, enables a significantly higher power density. It allows developers to achieve higher power levels in their applications with only half the component count of 1200 V solutions. This simplifies the overall design and enables a smooth transition from multi-level topologies to 2-level topologies.
In addition, the CoolSiC Schottky diode 2000V G5 utilizes the .XT interconnection technology that leads to significantly lower thermal resistance and impedance, enabling better heat management. Furthermore, the robustness against humidity has been demonstrated in HV-H3TRB reliability tests. The diodes exhibit neither reverse recovery current nor forward recovery and feature a low forward voltage, ensuring enhanced system performance.
The 2000 V diode family is a perfect match for the CoolSiC MOSFETs 2000 V in the TO-247Plus-4 HCC package that Infineon introduced in spring 2024. The CoolSiC diodes 2000 V portfolio will be extended by offering them in the TO-247-2 package, which will be available in December 2024.

U.S. Senators Gary Peters (MI) and Debbie Stabenow (MI) announced Hemlock Semiconductor (HSC) will receive up to $325 million in federal funding to build a new, state-of-the-art manufacturing facility on its existing campus in Hemlock, Michigan. The new facility will allow the company to expand production of hyper-pure polysilicon needed to manufacture semiconductor chips, which are used to make a wide variety of products including vehicles, cell phones, washing machines, medical devices, agricultural equipment, solar panels, and defense technologies.
The funding comes from the CHIPS and Science Act, legislation Peters and Stabenow helped craft and pass into law to boost U.S. production of semiconductor chips, create American jobs, and strengthen U.S. national security by lessening our dependence on foreign companies for these critical technologies. This investment is expected to create 180 good-paying manufacturing jobs, as well as thousands of construction jobs, in Michigan.
Hemlock Semiconductor (HSC) is the nation’s leading producer of hyper-pure polysilicon for the semiconductor and solar industries and one of only five companies in the world capable of producing the highest quality polysilicon for semiconductor chips.
“In Michigan, our workers know how to make things well and with precision. That’s why I’m thrilled to announce this major investment that is going to keep Michigan at the forefront of advanced manufacturing, nationally and globally, and create thousands of good-paying jobs in our state,” said Senator Peters. “As one of just five companies worldwide and the only company headquartered in the U.S. that produces hyper-pure polysilicon for semiconductors, Hemlock Semiconductor plays a critical role in both our economy and national security. I’m proud to have authored the provision in the CHIPS and Science Act that ensured HSC would be eligible for this grant and have since continued to advocate for HSC as they work to ramp up production here at home. This funding will be a catalyst to that effort.”
“Michigan knows all too well what happens when we are dependent on semiconductor chips made halfway around the world. That’s why, as part of the CHIPS and Science Act, I led the effort with Senator Peters and Representative Kildee to make sure semiconductor chips are manufacturing here in the United States and there is no better place to make them than Michigan. This important federal investment will boost Michigan manufacturing, fix our broken supply chains, lower costs, and bring jobs home,” said Senator Stabenow. “I applaud Hemlock Semiconductor’s leadership in semiconductor manufacturing and improving our supply chains.”
“HSC is proud to be a manufacturing powerhouse for two vital industries of the future—semiconductor and solar. Bolstered by the CHIPS Act, we are planning for a once-in-a-generation investment in advanced technologies to continue serving as a top polysilicon supplier to the leading-edge semiconductor market,” said HSC Chairman and CEO AB Ghosh. “Our customers want high quality and sustainably made polysilicon. This proposed investment demonstrates that the Biden-Harris Administration, Governor Whitmer and our Michigan congressional champions understand HSC’s unique ability to meet those demands and our crucial role in strengthening American interests. As the United States works to reshore critical supply chains, we hope to make additional investments.”
Peters and Stabenow have made strengthening American manufacturing and securing domestic supply chains a top priority. The CHIPS and Science Act includes a provision Peters and Stabenow authored to support the domestic production of mature semiconductor technologies and ensure that projects supporting critical manufacturing industries are given priority status, which would include the automotive sector. This is in addition to $50 billion already in the bill to incentivize U.S. production of all types of semiconductors – for a total of $52 billion.
The CHIPS and Science Act also included Peters’ bipartisan Investing in Domestic Semiconductor Manufacturing Act, which ensures federal incentives to boost domestic semiconductor manufacturing include U.S. suppliers that produce the materials and manufacturing equipment that enable semiconductor manufacturing – including HSC. This provision authored by Peters ensured HSC would be eligible for the grant funding announced today. The CHIPS and Science Act additionally authorized increased funding for the Manufacturing Extension Partnership (MEP) program, which has been a priority for Peters and Stabenow.
Last year, the Senate unanimously passed Peters’ bipartisan legislation to strengthen federal efforts to expand domestic manufacturing of semiconductor chips. Peters’ Securing Semiconductor Supply Chains Act would direct the U.S. Department of Commerce’s SelectUSA program, in collaboration with other federal agencies and state economic development organizations, to develop strategies that would attract investment in U.S. semiconductor manufacturers and supply chains.
