On June 7, 2024, Business Korea reported that Sam sung is strengthening its alliance in semiconductor packaging technology in an attempt to narrow the technological gap with TSMC. Sam sung expects to expand its 2.5D and 3D MDI (multi-chip integration) alliance this year, adding ten new members. Sam sung Electronics initiated the MDI Alliance in June 2023 to cope with the rapid growth of the mobile and HPC application chip market. Sam sung will work with its partner companies and major players in memory, substrate packaging, and testing.
Tungsten Boride WB2 is a compound composed of metallic tungsten and boron elements. It is emerging in the field of semiconductor packaging technology with its unique properties, providing new solutions for improving chip performance, enhancing thermal management capabilities, and ensuring long-term reliability.
Semiconductor packaging is the core link to ensure that chips can maintain performance in harsh environments and long-term operation. The introduction of Tungsten Boride WB2 is first of all due to its excellent wear resistance and hardness. The microhardness of up to 3700kg/mm² makes it an ideal choice for chip surface protective coating, effectively resisting physical wear during packaging and use, reducing circuit failure caused by external damage, and extending the working life of semiconductor devices.
With the continuous improvement of the power density of semiconductor devices, how to dissipate heat efficiently has become an urgent problem to be solved. The high melting point and excellent thermal conductivity of Tungsten Boride WB2 make it a rising star in thermal management materials. As a heat dissipation layer or thermal interface material, it can quickly transfer the heat generated by the chip to ensure the stability and safety of the device under high-load operation, which is particularly important for high-performance computing, data centers, and 5G communications and other high-energy consumption applications.
In semiconductor packaging structures, the performance of the conductive path directly affects the speed and quality of signal transmission. Tungsten Boride WB2 not only has metal-like conductivity but also maintains good conductivity in high-temperature environments, which makes it an ideal material for connecting leads, interconnect layers, and thin-film resistors. Especially in advanced packaging technologies such as fan-out packaging (Fan-Out) and three-dimensional integration (3D IC), this property of Tungsten Boride WB2 is crucial to achieving high-density and high-speed signal transmission.
In the pursuit of smaller, faster, and stronger semiconductor development trends, the versatility of Tungsten Boride WB2 provides unlimited possibilities for the innovation of packaging technology. As a substrate or interposer material, it can improve packaging density and optimize electrical performance while ensuring good thermal expansion matching, reducing internal stress caused by temperature cycling, and improving the reliability of the overall package.
