KYOTO, Japan, Jan. 20, 2026 /Kyodo JBN/ --
Nuvoton Technology Corporation Japan
Nuvoton Technology Corporation Japan (hereinafter "NTCJ") announced on January 20 the start of mass production of its high-power ultraviolet semiconductor laser (379 nm, 1.0 W), which delivers industry-leading (*) optical output in a 9.0-mm diameter CAN package (TO-9). This product achieves short wavelength, high output power, and long lifetime -- three elements previously considered difficult for ultraviolet semiconductor lasers -- through NTCJ’s proprietary device structure and advanced high-heat-dissipation packaging technology. As a result, it contributes to fine patterning and improved production throughput in maskless lithography for advanced semiconductor packaging.

(*) As of January 16, 2026, based on NTCJ’s research of semiconductor lasers emitting at 379 nm in a TO-9 CAN package under continuous-wave (CW) operation at a case temperature (Tc) of 25C.

As demand grows for information-processing capabilities driven by the evolution of artificial intelligence (AI), there is increasing need for higher semiconductor performance. On the other hand, as transistor miniaturization approaches its physical and economic limits, semiconductor back-end package technologies and advanced semiconductor packaging, which allow integration by arranging multiple chips side by side or stacking them vertically, have been attracting attention.

One element supporting the evolution of these packaging technologies is maskless lithography. As a key light source in maskless lithography, semiconductor lasers have faced growing demands for shorter wavelengths closer to the i-line (365 nm) and higher output to enable finer wiring and improve equipment throughput. To meet these requirements, NTCJ has leveraged over 40 years of experience in laser design and manufacturing to develop and commercialize an ultraviolet semiconductor laser with a wavelength of 379 nm and an output of 1.0 W.

Ultraviolet semiconductor lasers generally suffer from significant heat generation caused by low wall-plug efficiency (WPE), and a tendency for device degradation caused by ultraviolet light, making stable operation at high output levels above 1.0 W difficult. To address this, NTCJ took a dual approach by focusing on both a "device structure that enhances WPE" and a "high thermal conduction package technology that effectively dissipates heat," enabling NTCJ to develop a product that successfully combines short wavelength, high output, and long lifetime: a 1.0 W ultraviolet (379 nm) device. As a result, NTCJ is contributing to extending the lifetime of optical devices that utilize ultraviolet light.

The product has been newly added to NTCJ’s lineup of "semiconductor laser-based alternatives to mercury lamps," providing customers with a new choice.

Details of the new product will be showcased at NTCJ’s booth at SPIE Photonics West 2026 in San Francisco, USA, and at OPIE’26 in Yokohama, Japan. NTCJ sincerely looks forward to welcoming visitors.

Semiconductor lasers with a wavelength of 402 nm are being utilized as alternative light sources to the h-line of mercury lamps in applications such as Laser Direct Imaging and resin curing. In recent years, there have been growing expectations for applications in even more areas, including medical devices. In these applications, it is necessary to integrate the light source system into a limited space, which has created demand for semiconductor lasers that are both compact and high-powered. However, as the optical output power of semiconductor lasers increases, the amount of heat generated also rises, requiring larger heat dissipation structures and resulting in challenges related to package size limitations.

To address this, NTCJ has evolved its proprietary chip design and thermal management technologies based on over 40 years of experience in laser design and manufacturing. By designing to reduce optical loss inside the laser chip, heat generation is suppressed. In addition, a new optical facet structure that withstands strong laser light has been adopted, enabling the previously difficult combination of compact size, high output power and long-life. As a result, NTCJ has achieved an optical output power level of 1.7W in the industry-standard TO-56 CAN package, representing approximately a 40% increase in output power compared to NTCJ’s previous products (*2). Furthermore, the reliability indicator MTTF has also been significantly improved. This new product not only contributes to space-saving and long-life in existing applications but is also expected to expand and create new applications that were not possible with conventional light sources.

In addition, this product is newly added to NTCJ’s lineup of mercury lamp replacement solutions using semiconductor lasers, providing customers with new options. This enables flexible product selection according to application, installation environment, and required performance, improving the freedom of system design.

1. Superior image-processing engine for improving visibility and comfort of HMI equipment

For Electronic Mirrors
Gerda-4M solves the issues that conventional e-mirrors have, such as glare caused by strong lights and reduced visibility due to loss of detail in high-contrast lighting scenarios, especially at night, by using a "local contrast function" that locally adjusts the screen contrast based on the luminance distribution of each area. In addition, low-latency processing of less than one frame enables real-time display improvements.

Figure1: https://cdn.kyodonewsprwire.jp/prwfile/release/M108245/202505209125/_prw_PI2fl_2Cch7lSf.jpg

For AR-HUDs
AR-HUD displays must align precisely with windshield curvature and driver's line of sight. The image-warping engine in Gerda (TM) enables free image deformation with low latency of less than one frame, allowing it to fit the windshield. It also supports "dual projection," which projects images both near and far focus with a single chip.

Figure2: https://cdn.kyodonewsprwire.jp/prwfile/release/M108245/202505209125/_prw_PI3fl_m566UT8D.jpg

For Cluster Meters
With a 2.5D graphics engine (GFX), Gerda (TM) enables user interface (UI) design that simulates 3D effects using 2D elements. This improves depth perception and readability, contributing to more accurate and timely decision-making by the driver. Additionally, in combination with an image compression engine, it supports high-resolution output of WXGA@60FPS, providing a modern, high-quality dashboard experience.

2. Generally, high-performance HMI solutions require external memory. NTCJ's Gerda (TM) Gen-4 series is embedded with high speed and large capacity memory which eliminates external memory, helping to reduce the number of components and system costs. In addition, Gerda-4L is equipped with a dedicated image compression engine, achieving real-time processing while using only half the memory -- making it possible to display high-resolution images at WXGA@60FPS only using embedded memory.

Figure3: https://cdn.kyodonewsprwire.jp/prwfile/release/M108245/202505209125/_prw_PI4fl_h4akP54x.jpg

3. The Gen-4 Gerda (TM) lineup includes display safety functions such as video signal monitoring and alert display monitoring, and contributes to realizing system designs that meet ISO26262 ASIL-B requirements by supporting fail-safe and real-time monitoring.

Additionally, the integrated Hardware Security Module (HSM), compliant with EVITA-Full, enables secure OTA software updates and a secure boot which allows only trusted software boots -- protecting against vehicle cybersecurity threats.

Nuvoton Releases Plan to Launch Mass Production of New Industrial BM-ICs

Nuvoton Technology — Thu, 20 Feb 2025 17:00:00 +0900

KYOTO, Japan, Feb. 20, 2025 /Kyodo JBN/ --
Nuvoton Technology Corporation Japan
Nuvoton Technology Corporation Japan (NTCJ) has developed new industrial 17-cell BM-ICs "KA49701A" and "KA49702A" for 48V batteries. Mass production will start from April 2025. These products enhance the safety of battery systems and ensure simple safe system construction.

Image: https://cdn.kyodonewsprwire.jp/prwfile/release/M108245/202502124110/_prw_PI1fl_tJjts0mQ.png

1. The battery monitoring ICs play a role in ensuring the system operates safely during anomalies such as overcharging or over-discharging of the battery. However, if the main circuits performing cell voltage measurements such as the AD converter or multiplexer of the BM-IC fail, it needs to ensure system safety with external protection circuits, but this increases board area and system cost. The major internal circuits of this product are equipped with diagnostic and fail-safe functions. This diagnostic function can detect main circuit failures and control the cut-off switch, achieving both enhanced BMS safety and reduced system cost.

Figure (Traditional Chinese): https://cdn.kyodonewsprwire.jp/prwfile/release/M108245/202502124110/_prw_PI4fl_ins2617Q.png

2. By reducing noise levels on the 16-bit AD converter and incorporating a digital filter, NTCJ has achieved industry-leading voltage measurement accuracy of +/-2.9mV (*1). By improving voltage measurement accuracy, maximum battery capacity can be used. Furthermore, precise voltage measurement has been achieved over a wide temperature range. It is also suitable for applications requiring high voltage measurement accuracy in cold and hot environments, such as stationary battery systems compliant with the relevant Chinese national standard (*2).
(*1) According to a survey by Nuvoton in the industrial BM-IC field as of February 2025.
(*2) GB/T34131-2023, within the system +/-5mV @-20C to 65C.

3. By shortening the cell voltage measurement time, which has high power consumption, operating current has been achieved at 260 microampere, less than 1/10th of NTCJ’s previous standards. This enables long battery drive times. Also, optimization of the circuit design has reduced shutdown current consumption to 0.1 microampere or less. Using NTCJ’s IC, self-discharge can be minimized, preventing deterioration due to over-discharge when LIBs are transported over long distances and stored long-term.

Contributing to Lower Power Consumption in Server with High-efficiency, High-airflow Cooling Fan..

Nuvoton Technology — Mon, 22 Jul 2024 17:00:00 +0900

KYOTO, Japan, July 22, 2024 /Kyodo JBN/ --
Nuvoton Technology Corporation Japan
Nuvoton Technology Corporation Japan (NTCJ) announced on July 8 the launch of a new 48V direct drive motor driver IC that enables high efficiency and high airflow with high speed rotation in fan motors.

Image: https://cdn.kyodonewsprwire.jp/prwfile/release/M108245/202407123567/_prw_PI1fl_92dLE2oI.png

1. The newly developed motor driver IC incorporates a 100V-rated voltage control circuit, based on the high-voltage control circuit technology that NTCJ has cultivated over the years, into a small 4mm x 4mm QFN package, while significantly reducing external components such as step-down regulators (53% reduction from the conventional 24V product). This reduces power loss and enables installation onto 1U-size (40mm x 40mm) fans, contributing to high-density data processing.

2. The high-speed data processing of the AI server requires the fan motor to rotate at a higher speed in order to cool down the increasing heat generation. Simultaneously, it is necessary to suppress the rising trend of power consumption in fan motors, and its vibrations that adversely affect the HDD error rate. NTCJ’s proprietary technology for real-time feedback control of motor drive current value and phase with high resolution makes it possible to reduce the power consumption of single-phase fan motors by 30% and vibration by 20 dB compared to conventional motors, even at high speeds when higher airflow can be output. This contributes to high-speed, large-capacity data processing that requires high cooling capabilities.

3. In general, it is difficult to detect reverse rotation in a single-phase fan motor. So, when the fan motor stops and there is interference in between multiple fans, or when the fan motor rotates in reverse due to disturbances such as the inflow of external air, it is difficult to restart the fan motor in conventional products. However, NTCJ’s proprietary rotation control algorithm can achieve reliable and stable restart even from reverse rotation speed that is twice as high as the conventional products.

Figure1: https://cdn.kyodonewsprwire.jp/prwfile/release/M108245/202407083263/_prw_PI1fl_b1WW8Has.png

2. Accurate Distance Measurement for Moving Objects
With four embedded memories within each pixel, Nuvoton’s new TOF sensor outputs distance images in a single frame. This innovative design significantly reduces motion blur and measurement errors in moving objects by capturing and calculating distance from four types of imaging signals within one frame. This feature is particularly suited for applications requiring dynamic object detection and recognition, such as obstacle detection for autonomous mobile robots (AMRs) and airbag intensity control in vehicles.

Figure2: https://cdn.kyodonewsprwire.jp/prwfile/release/M108245/202407083263/_prw_PI2fl_V2L6WaJJ.png

3. Integrated Distance Calculation Circuit for Fast and Accurate Sensing
Nuvoton’s new TOF sensor is equipped with an integrated distance calculation circuit and a signal correction ISP, enabling it to output high-speed, high-precision distance (3D) images at up to 120 fps (QVGA) without delay. This eliminates the need for distance calculation by the system processor, reducing the processing overhead and enabling faster sensing systems. Additionally, the sensor can simultaneously output distance (3D) and IR (2D) images, useful for applications requiring both high precision and recognition/authentication functions.
