ATC 2.0 Option Enables Dynamic Multisite Sensing and Regulation of Device Temperature for Optimized Test of High-End Automotive SoCs
Advantest announced a new Active Thermal Control (ATC) option for its M4841 high-volume device handler in October. ATC 2.0 provides dynamic regulation of temperature fluctuations caused by automotive semiconductors self-heating during test, helping to ensure more accurate production test of up to 16 advanced systems-on-chip (SoCs) in parallel with higher throughput and shorter test times.
Massive amounts of data processing are required for devices used to power electric vehicles (EVs) and other fast-growing, data-intensive automotive applications such as infotainment systems and forthcoming Level 4 autonomous driving. Advances in semiconductor manufacturing processes bring improvements in functionality as well as enhanced power efficiency for these advanced devices. As a result, thermal design power is actually increasing, causing devices to self-heat during test and making it more difficult to control test temperature. This creates a need for handlers that can perform prompt, stable device temperature management.
Replacing the handler’s prior passive thermal control technology, integrated ATC enables the M4841 to provide a stable, consistent test environment with fast response and high load-tracking characteristics that maintain the device’s internal temperature at the set test temperature, even if dynamic heat fluctuation occurs during the test. This stability enables users to build test programs with unparalleled implementation flexibility – in turn, significantly enhancing overall test productivity.
Advantest’s M4841 handler with ATC 2.0 enables high-throughput test of up to 16 devices in parallel, yielding very high device volumes and supporting a range of complex ICs and packages. Its advanced performance capabilities and features make the M4841 the optimal test handler for high-volume production of devices used in consumer products such as portable digital equipment and automotive systems.
MPT3000 Is World’s First SSD Production Tester to Be Certified by PCI-SIG® for High-Speed PCIe® Gen 5 Compliance Testing
Advantest announced in September that its MPT3000 solid-state drive (SSD) test system has become the world’s first SSD production tester to be certified by PCI-SIG® for high-speed compliance testing of PCI Express® (PCIe®) fifth-generation (Gen 5 or 5.0) devices. Advantest completed the rigorous testing process and was awarded certification in August 2023.
Previously approved for PCIe 4.0 compliance testing, the MPT3000 is now also approved for official PCIe 5.0 compliance and certification testing. The PCIe 5.0 certification was awarded specifically to two key products in the MPT3000 family: the MPT3000ES3 for engineering and the MPT3000HVM3 for high-volume manufacturing.
PCI-SIG compliance testing ensures not only adherence to the PCIe standard but also product interoperability, providing integrators with Add Newthe confidence to adopt certified products for their application needs. Only equipment that has passed the PCI-SIG’s intensive series of compliance tests – including electrical, protocol and interoperability tests – can be included in the PCI-SIG’s official Integrators List.
Since its introduction in 2014, the MPT3000 has become the de facto industry standard for SSD test, with a broad installed base of customers that includes integrated device manufacturers (IDMs), fabless chipmakers, and outsourced semiconductor assembly and test (OSAT) providers. Combining Advantest’s expertise in high-speed system-on-chip (SoC) testing with state-of-the-art electronics architecture, the MPT3000 features multi-protocol capability and high parallelism to enable full performance testing of a range of SSD form factors.
As SSDs increase in speed, thermal management becomes a bigger challenge. The most recent additions to the MPT3000’s capabilities, announced in early August 2023, are the Independent Thermal Control (ITC) device interface boards (DIBs) and Engineering Thermal Chamber (ETC). These new thermal control products were developed to manage higher-wattage PCIe Gen 5 devices and are compatible with all SSD form factors tested on the MPT3000ES3 and MPT3000HVM3 systems, enabling manufacturers to accelerate testing within actively controlled thermal environments.
Independent Thermal Control Board and Engineering Thermal Chamber Targeting Early SSD Product Development Stages with Per DUT Thermal Control
In August, Advantest announced two new additions to its MPT3000 solid-state drive (SSD) test platform. The Independent Thermal Control (ITC) device interface boards (DIBs) and Engineering Thermal Chamber (ETC) target early engineering adoption of the MPT3000 by enabling efficient, small-batch engineering, quality assurance and early test development for SSD devices.
Advanced computing standards, such as PCI Express fifth-generation (PCIe Gen 5), enable higher-speed SSD devices with greatly expanded bandwidth for use in advanced data centers and other demanding storage applications. These faster, higher-capacity devices must be characterized and tested in thermal environments that accurately replicate operating temperatures.
Designed for device test qualification and validation, the ETC is integrated into the MPT3000ES3 test system to handle the highest-power PCIe Gen 5 DUTs. The unit enables accurate environmental temperature control within the chamber from -10 to 85°C, utilizing air flow to accurately condition up to 32 4-lane DUTs. The ETC is well suited for characterizing small batches of DUTs at a set temperature within the range stated.
Created for high-volume production test and qualification, the MPT3000HVM3 test systems support ITC DIBs, allowing the user to accurately set and maintain a constant drive temperature. Using active temperature feedback from the DUT, the fan speed is controlled to maintain a constant DUT temperature. This is an improvement from standard DIBs, which supply constant cooling air and allow the DUT temperature to fluctuate with the wattage of the test cycle. ITC DIBs feature air channels on either side of the DUT to maintain a constant DUT temperature on all DUTs, even during asynchronous testing cycles.
Advantest recently announced that it shipped its 10,000th V93000 system-on-chip (SoC) test system to longtime customer Infineon Technologies, the world’s number one automotive semiconductor supplier. The milestone system is a V93000 configuration developed to address the diverse test needs of power, analog, microcontroller and sensor ICs used in automotive and microcontroller applications. Ever-increasing semiconductor content in today’s automobiles is creating a pressing need for the V93000’s combination of advanced test capabilities and leading cost-of-test savings.
“Advantest’s V93000 tester has proven to be a highly effective digital, power and mixed-signal tester for us. The partnership with Advantest has helped to enable fast time-to-market while hitting our challenging cost-of-test targets,” said Ralf Schuster, senior vice president, Test and Automation Technologies, Infineon. “We have worked with Advantest for many years, and we are pleased to be the recipient of the 10,000th V93000 shipment.”
In the more than two decades since its introduction, the flexible, scalable V93000 has become Advantest’s flagship SoC test platform. The company offers a wide range of V93000 options together with complementary test instruments – including universal analog and digital test cards, RF instrumentation and mixed-signal cards, and best-in-class DPS and floating-power VI cards – as well as the user-friendly SmarTest system software environment. The newest V93000 offering is the EXA Scale™ generation system for testing a wide range of devices, from current and future generations of low-cost Internet of Things (IoT) chips to high-end automotive devices, highly integrated multicore processors, and advanced digital ICs up to the exascale performance class.
The market for photomasks used in high-numerical-aperture (NA) extreme-ultraviolet (EUV) lithography is growing quickly as chipmakers seek patterning solutions for sub-5nm masks. To take advantage of this growth, Advantest is leveraging the capabilities of its proven E3650 multi-vision metrology scanning electron microscope (MVM-SEM®). Since its introduction in 2018, the E3650 has become the standard for EUV mask measurement, making the system well-positioned for the high-NA market.
Highly advanced masks are vital for the development of complex chips that consume less power, such as those implemented in mobile phones. EUV lithography was developed to accommodate the printing of sub-7nm mask features, which 193nm-wavelength lithography systems are unable to handle. However, single-pattern EUV reaches its limit at around the 5nm node. At 3nm and beyond, high-NA EUV, which enables scaling down to the angstrom level, offers a simpler approach than costlier and more complex EUV double patterning. According to ASML, “High-NA EUV will bring multiple benefits to the semiconductor market such as reduction of process complexity, yield improvement, higher resolution enabling printability of smaller features at increased density, and cost of technology reduction.”1
The E3650 MCM-SEM uses Advantest’s proprietary electron beam scanning technology to measure fine pattern dimensions on photomasks with high precision and stability. The system’s higher throughput enables massive measurement required by more complex patterning and an increased number of masks due to multiple patterning. Key features include fast move-acquire-measure (MAM) time, large field measurement, long-term stability of critical dimension (CD) measurements, design-based metrology support and 3D observation.
“The E5620 has proven its effectiveness in measuring masks for both 193nm and EUV lithography, delivering improvements in accuracy and throughput compared to earlier models in the E36XX series. These capabilities enable enhanced analysis as well as more efficient mass production of photomasks,” said Stuart Ainslie, senior director of business development, Advantest Europe. “Through its combination of unique features and our stellar global support, the E3650 has become the standard solution for measuring EUV masks. We look forward to capitalizing on this success in the high-NA EUV space.”
