Advantest Rolls Out Thermal Control Products for MPT3000 Solid-State Drive Test Platform

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 Targets High-Numerical Aperture (NA) EUV Photomasks with Industry-Leading E3650 MVM-SEM

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.”
