Under the development law of the semiconductor industry — “one generation of technology, one generation of process, and one generation of equipment” — the key to equipment upgrades and iteration lies in breakthroughs in the performance of precision core materials.
From lithography machines to etching systems, and from wafer stages to process chambers, high-end semiconductor equipment imposes extremely demanding requirements on materials in terms of thermal stability, structural rigidity, lightweight design, and heat dissipation performance.
Loongceram has been deeply engaged in the R&D and industrialization of high-purity cordierite ceramic materials. With core products whose performance rivals international benchmarks while offering additional advantages, Loongceram has become a key material supplier supporting the localization and upgrading of semiconductor equipment, effectively addressing the “bottleneck” challenges in critical high-end equipment materials.
Comprehensive Performance Breakthroughs to Meet High-End Semiconductor Requirements
While maintaining its core advantage of low thermal expansion, Loongceram high-purity cordierite has achieved multi-dimensional breakthroughs compared with industry benchmark materials such as Zerodur, traditional glass-ceramics, and quartz glass, including improvements in elastic modulus, heat dissipation capability, and lightweight performance.Each property is precisely aligned with the demanding operating conditions of semiconductor equipment.To provide a clearer understanding of the advantages of Loongceram high-purity cordierite, the following comparison illustrates the key material properties.
Material Property Comparison
| Property | Loongceram High-Purity Cordierite | Zerodur | Glass-Ceramic / Quartz Glass |
|---|---|---|---|
| Coefficient of Thermal Expansion | Near-zero expansion, comparable to Zerodur, stable across a wide temperature range | Near-zero expansion | Higher expansion; deformation easily occurs with temperature fluctuation |
| Elastic Modulus | About 55% higher, providing high rigidity and deformation resistance | Conventional level | Insufficient rigidity; deformation may occur during high-speed operation |
| Thermal Conductivity | Approximately 3× that of Zerodur, enabling efficient heat dissipation | Conventional thermal conductivity | Poor heat dissipation, prone to localized heat accumulation |
| Density | Slightly higher than Zerodur, relatively lightweight | Standard density | Higher density; larger mass under equivalent stiffness |
| Thermal Shock Resistance | Excellent, resistant to rapid heating and cooling without cracking | Good | Relatively poor; prone to fracture under sudden temperature changes |
| Dielectric Constant | Low, compatible with semiconductor electromagnetic environments | Conventional | Higher dielectric constant; more susceptible to electromagnetic interference |
The combination of high elastic modulus and relatively low density enables Loongceram high-purity cordierite to achieve extreme lightweight performance while maintaining ultra-high stiffness.Under equivalent stiffness requirements, the mass of a platform substrate made from cordierite is significantly lower than that of glass-ceramic or quartz glass, greatly improving the dynamic response speed of equipment motion systems and perfectly matching the high-speed, high-precision operation requirements of semiconductor equipment.Another key advantage of Loongceram high-purity cordierite is its thermal conductivity, which is approximately three times that of Zerodur.During processes such as laser exposure, plasma processing, and high-speed scanning, semiconductor equipment often experiences localized heat accumulation. Loongceram cordierite enables rapid and efficient heat transfer and dissipation, fundamentally reducing process deviations and wafer damage caused by heat buildup, while enhancing the overall thermal stability of semiconductor equipment and safeguarding manufacturing yield.
A Key Material for Lithography Systems
Lithography machines are often referred to as the “crown jewel” of semiconductor equipment. Core components such as wafer stages and mirror blocks must maintain extreme thermal and structural stability while operating under high-speed scanning and nanometer-level positioning accuracy.The performance requirements for materials used in these systems are extremely demanding.
Traditional materials such as glass-ceramics, quartz glass, and ULE glass are increasingly unable to meet the precision requirements of next-generation lithography machines.
With its near-zero thermal expansion, Loongceram high-purity cordierite perfectly meets the thermal stability requirements at lithography system operating temperatures, fundamentally eliminating material deformation caused by temperature fluctuations.
At the same time, its high elastic modulus effectively resists mechanical deformation during high-speed platform movement, enabling wafer stages and mirror components to maintain precise positioning even under high-frequency, high-speed motion, thereby providing a solid material foundation for nanometer-level lithography accuracy.
It can be said that Loongceram high-purity cordierite is an ideal material for core lithography components and an important material solution supporting the advancement of next-generation lithography equipment.
Enabling the Entire Front-End Semiconductor Process
Beyond lithography systems, Loongceram high-purity cordierite also plays a critical role in other front-end semiconductor processing equipment, including etching systems and CVD/PVD deposition equipment, thanks to its comprehensive performance advantages of low thermal expansion, high rigidity, lightweight structure, thermal shock resistance, and low dielectric constant.
