Xiamen University and Huawei jointly announced a new achievement: heterogeneous integration of 4-inch diamond wafers.​


Xiamen University, in collaboration with Huawei Technologies and Xiamen Yuntian Semiconductor, announced a significant advancement in chip thermal management. The research, published at the 2026 IEEE 76th Electronic Components and Technology Conference (ECTC), addresses the critical challenge of heat dissipation in high-performance chips used in 5G, AI, and automotive electronics.

As chip power consumption exceeds 1000W, traditional cooling methods are reaching their limits. Diamond, with its ultra-high thermal conductivity (>2000 W/(m·K)), is an ideal candidate for next-generation cooling, but integrating it with silicon semiconductors has been difficult due to issues like high interface thermal resistance and wafer warpage.

The team developed a 4-inch silicon/diamond wafer-level collective bonding solution. Key technical steps included:​
  • Using temporary bonding to support the diamond wafer, reducing warpage by approximately 67%.​
  • Depositing reactive metal nanolayers after surface plasma activation.​
  • Achieving wafer-level bonding at a low temperature of 200°C.​
Performance Results:​
  • Successfully bonded 65 silicon dies to a single 4-inch polycrystalline diamond wafer.​
  • Achieved an extremely low void rate of only 0.31% at the interface.​
  • Reached a minimum thermal boundary resistance of 20.3 m²·K/GW, outperforming many existing bonding methods.​
The integrated samples passed rigorous reliability tests, including 1,000 hours of storage at 150°C, six reflow soldering cycles at 260°C, and 1,050 thermal cycles between -55°C and 125°C.

This study provides a scalable, low-temperature manufacturing path for integrating diamond heat spreaders into advanced packaging. It marks a significant step toward moving diamond thermal materials from laboratory verification to industrial-scale application, offering a promising solution for thermal management in future high-power, high-density chips.​

CXMT's DDR5 RAM isn't as performant or as consistent as SK hynix dies, early testing shows — reveals resistance to voltage scaling and inferior manual overclocking capabilities​

>Different batches of CXMT-equipped memory perform differently, too, so silicon lottery plays a much bigger role than it would with other vendors.

Probably needs a bit more time

Not many do this amount of fine tuning on their RAM in the consumer space, most play around with their GPUs and CPU clocks followed by their cooling. RAM fine tuning is really far down the list of things to fine tune lol.

Not to mention the fine tunes still impact the CXMT RAM, just that the article only stated that it's not as much as the big 3 and he doesn't really go into the numbers, so at that point it might be single percentages that are imperceptible to the average and even the hardcore gamers and only really noticeable when you are running an AI data centre.
