ROHM Offers the Industry’s Smallest* Terahertz Wave Oscillation and Detection Devices

　　ROHM has begun offering samples of the industry’s smallest* terahertz (THz) wave oscillation and detection devices utilizing semiconductor elements known as Resonant Tunneling Diodes (RTDs). Terahertz waves are anticipated to be applied to non-destructive testing, imaging, and sensing in the medical and healthcare sectors, as well as potentially future ultra-fast communication technologies. Providing these devices contributes to the advancement of terahertz wave applications.　　ROHM has developed a 0.5mm × 0.5mm RTD chip for terahertz wave generation and detection, capable of oscillating and detecting terahertz waves at a frequency of 320GHz (typ.) with an output power ranging from 10 to 20µW. ROHM will begin offering samples of this RTD element mounted in a PLCC package (4.0mm × 4.3mm) commonly used for LEDs. With an extremely compact size, typically than one-thousandth that of conventional oscillators, this innovation enables easy development of terahertz wave applications, even in space-constrained environments.　　By positioning the antenna surfaces of the oscillation and detection devices facing each other 10mm apart, a dynamic range of 40dB (typ.) can be achieved. Both oscillator and detector maintain a drive power consumption of 10mW (typ.), while their ability to oscillate and detect terahertz waves at room temperature eliminates the need for cooling equipment required with some conventional methods. These compact, power-saving devices are almost unaffected by the operating environment, enabling use in a wide range of applications.　　ROHM offers samples of terahertz wave oscillation and detection devices at a sample price of $990.0/unit (excluding tax), which is less than one-tenth the price of conventional devices. ROHM also provides evaluation kits that include an evaluation board and other components, allowing users to easily integrate the devices into a research and development environment. For more information, please contact a sales representative or visit the contact page on ROHM’s website. The sale of sample products and evaluation kits requires the prior signing of a non-disclosure agreement (NDA) with ROHM.　　Professor Safumi Suzuki, Laboratory for Future Interdisciplinary Research of Science and Technology, Institute of Integrated Research, Institute of Science Tokyo      “Terahertz waves are expected to be applied to various fields such as imaging, sensing, and wireless communications due to their excellent characteristics and high degree of safety. However, research and development for commercialization has traditionally required large-scale equipment and substantial costs.　　In this context, the RTD terahertz wave device - developed through years of collaborative research with ROHM - is an ultra-small 4.0mm × 4.3mm device that challenges conventional norms while featuring astonishingly low power consumption and implementation costs. With the launch of device samples, we anticipate that many private companies and research institutions will begin exploring terahertz wave research.　　We hope that the use of terahertz waves in various fields will lead to the creation of new applications with functions that were previously difficult to achieve. Going forward, we will continue to contribute to society through the development of terahertz wave devices in partnership with ROHM.”　　Ken Nakahara, General Manager of Center, ROHM Research & Development Center, ROHM Co., Ltd.      “The terahertz (THz) R&D team and I are very excited and proud to have reached the point where we can bring this technology to market. We have dedicated ourselves to THz devices for about 15 years; the journey has not been easy. We gathered the forces of industry, academia, and government along the way, and have successfully established the position that ROHM holds today.　　The team understands that this announcement is just a small step toward the commercialization of THz technology, but at the same time, it is a giant leap for us. We believe that this small beginning will grow big and contribute to the well-being of our society.”　　Background and Development Summary        Occupying the frequency region between radio waves and light, terahertz waves exhibit a variety of distinctive characteristics, including excellent permeability similar to radio waves, straight-line propagation akin to laser beams, and unique absorption properties for materials such as polymers. As such, they are expected to be utilized for non-destructive testing, imaging of humans and materials without the use of dangerous radiation, high-speed communication as an alternative to conventional wireless transmission, and high-resolution radar sensing. However, conventional methods often require large equipment sizes and high implementation costs often ranging from tens of thousands to hundreds of thousands of dollars, making it challenging for private companies to actively pursue research or commercialize in the field of practical terahertz applications.　　Since the late 2000s, ROHM has engaged in joint research with numerous universities and research institutes, such as the Institute of Science Tokyo and Osaka University. The key aim: developing terahertz wave oscillation and detection devices using RTD technology. ROHM is also involved in several consortia, including national projects (government R&D initiatives) sponsored by the Ministry of Internal Affairs and Communications (MIC), the National Institute of Information and Communications Technology (NICT), and the Japan Science and Technology Agency (JST), as well as the XG Mobile Promotion Forum and the Terahertz System Application Promotion Council. ROHM will continue to focus on device development while contributing to the early industrialization and social integration of terahertz technology.　　Professor Safumi Suzuki Profile        Doctor of Engineering, Professor at the Laboratory for Future Interdisciplinary Research of Science and Technology, Institute of Integrated Research, Institute of Science Tokyo. His research targets the development of terahertz wave devices using resonant tunneling diodes (RTDs).　　• Career　　March 2009　: Completed a doctoral program at the Interdisciplinary Graduate School of Science and Engineering, Tokyo Institute of Technology　　April 2009　: Assistant Professor, Interdisciplinary Graduate School of Science and Engineering, Tokyo Institute of Technology　　April 2014　: Associate Professor, Faculty of Engineering, Tokyo Institute of Technology　　August 2024　: Professor, Laboratory for Future Interdisciplinary Research of Science and Technology, Institute of Innovative Research, Tokyo Institute of Technology　　October 2024　: Professor, Laboratory for Future Interdisciplinary Research of Science and Technology, Institute of Integrated Research, Institute of Science Tokyo　　Terminology         Resonant Tunneling Diode (RTD)　　A terahertz wave light source that uses semiconductor elements to provide advantages such as small size, low power consumption, and the ability to oscillate at room temperature. Following extensive research and development with various universities and research institutions, ROHM has successfully achieved in-house production of RTD devices capable of efficient terahertz wave oscillation and detection.　　PLCC　　Short for Plastic Leaded Chip Carrier, a type of IC package used for semiconductor integrated circuits.　　Conventional THz Generation Methods　　Conventional methods for generating terahertz waves include the ‘frequency multiplication’ method, which converts the frequency of an electrical signal into an integer multiple for output, and the “photomixing” method that produces terahertz waves from the difference frequency created when two laser beams of different wavelengths are mixed in a photomixer. Both approaches necessitate large or medium sized costly equipment to generate terahertz waves.　　Dynamic Range　　A performance metric for analog devices indicating the difference or ratio between the maximum and minimum values of a signal that can be handled. Like for other radio frequency applications, for terahertz waves dynamic range usually expressed in decibels (dB).

ROHM’s New TVS Diodes: Supporting High-Speed CAN FD In-Vehicle Communication Systems for Autonomous Driving

　　ROHM has developed bidirectional TVS (ESD protection) diodes compatible with CAN FD (CAN with Flexible Data rate) high-speed in-vehicle communication. Such protocols are seeing an increased demand in line with the ongoing advancement in autonomous driving and advanced driver assistance systems (ADAS). CAN FD is a crucial communication technology for safe, real-time data transmission between ECUs (Electronic Control Units) in vehicles. The new products achieve high-quality in-vehicle transmission by protecting electronic devices such as ECUs from surges and electrostatic discharge (ESD) while maintaining signal integrity in high-speed communication systems such as CAN FD.　　The rapid evolution of autonomous driving technology and ADAS is boosting the demand for faster, more reliable automotive communication. Autonomous driving in particular requires quick and accurate processing of vast amounts of data from sensors such as cameras, LiDAR and radar - leading to the adoption of CAN FD that enables faster, higher capacity data transfer compared to traditional CAN used in automotive communication.　　At the same time, to achieve high-speed in-vehicle communication, it is necessary to ensure stable transmission even under harsh environments. This has led to a growing demand for protection components that offer low terminal capacitance along with superior surge current rating and clamping voltage performance. As a result, the market for TVS diodes for automotive communication is expected to continue to grow in the future.　　To meet market needs, ROHM developed the ESDCANxx series that combines low terminal capacitance with excellent surge tolerance. Two package types are available: SOT-23 (2.9mm × 2.4mm) and DFN1010 (1.0mm × 1.0mm), both supporting standoff voltages (VRWM) of 24V and 27V. The SOT-23 package includes four models: 24V ESDCAN24HPY / ESDCAN24HXY and 27V ESDCAN27HPY / ESDCAN27HXY. Similarly, the DFN1010 package is also offered in four models: 24V ESDCAN24YPA / ESDCAN24YXA and 27V ESDCAN27YPA / ESDCAN27YXA, totaling 8 products in the lineup.　　The new products feature an optimized element structure that reduces terminal capacitance to a maximum of 3.5pF, preventing signal degradation during high-speed communication. High surge tolerance is also achieved, significantly improving the protection of electronic devices in automotive environments. For example, the 27V products of the DFN1010 package delivers approx. 3.2 times higher surge current rating and 16% lower clamping voltage compared to standard CAN FD-compatible products. This effectively safeguards expensive surge-sensitive electronic devices such as in-vehicle ECUs, ensuring high reliability even under harsh automotive environments. Going forward, ROHM will continue to develop products that support even faster in-vehicle communication in autonomous driving and communication environments - contributing to realizing a safer, more advanced mobility society.　　Application Examples        • Autonomous driving and Advanced Driver Assistance Systems (ADAS)　　• Automotive electric powertrain systems　　• In-vehicle infotainment systems　　Online Distributor Information        Sales Launch Date: December 2024　　Pricing: $0.9/unit (excluding tax)　　Target Products　　SOT23 Package: ESDCAN24HPY, ESDCAN24HXY, ESDCAN27HPY, ESDCAN27HXY　　DFN1010 Package: ESDCAN24YPA, ESDCAN24YXA, ESDCAN27YPA, ESDCAN27YXA　　Terminology         CAN FD (CAN with Flexible Data Rate)　　An extension of the CAN (Controller Area Network) standard, CAN FD offers faster data transfer speeds compared to conventional CAN, enabling the exchange of large volumes of data. Real-time communication between multiple in-vehicle electronic units (ECUs) is essential in systems like autonomous driving and ADAS.　　TVS Diode (Transient Voltage Suppression Diode)　　A semiconductor device designed to protect circuits from overvoltage, surges, and electrostatic discharge (ESD). TVS diodes absorb sudden voltage and current spikes (surges) to prevent circuit damage and malfunction. In automotive environments, safeguarding against severe electrical fluctuations is crucial.　　Terminal Capacitance　　Unwanted capacitance components that arise in electronic parts. When terminal capacitance is high, signal degradation occurs during high-speed transmission, making it important to reduce terminal capacitance for in-vehicle communication　　Surge Current Rating　　The maximum surge current a TVS diode can withstand. The higher the surge current rating, the stronger the protection against severe electrical fluctuations in automotive environments.　　Clamping Voltage　　The voltage maintained in the circuit when the TVS diode suppresses overvoltage caused by surges or other transient events. A lower clamping voltage provides more effective protection for circuits and devices, increasing the reliability of automotive equipment.
