GORGEOUS CERAMICS (GGS Ceramic) manufactures custom aluminum nitride (ANT) wafers for semiconductor, electronics, laser, vacuum, and high-power thermal management applications. Our ANT wafers are made from ultra-high purity (99.5%) aluminum nitride ceramic, exhibiting excellent thermal conductivity (up to 200 W/mK at room temperature (25°C), insulation, and a near-silicon coefficient of thermal expansion, making them ideal ceramic wafers for various advanced electronic packaging and semiconductor manufacturing.
We have developed a method for directly bonding aluminum nitride to ANT-coated wafers. Direct wafer bonding requires a smooth, flat, and hydrophilic surface that can be activated by appropriately charged hydrogen molecules. We can provide ANT wafers with extremely smooth surfaces (Ra≤0.03µm) and flat surfaces.
Whether you need prototyping or mass production, GORGEOUS CERAMICS (GGS) offers precision machining and special hole or groove machining services according to your drawings or specifications, and provides free standard ANT ceramic samples for your reference.
Product Highlights
High Thermal Conductivity for Rapid Chip Heat Dissipation
GORGEOUS CERAMICS (GGS Ceramic) aluminum nitride wafers boast exceptional thermal conductivity, more than 7 times that of alumina ceramics (approximately 24 W/m·K), enabling rapid heat transfer from your chip to the cooling system.
For high-power LEDs, IGBTs, SiC/GaN power devices, lasers, and RF modules, our wafers effectively reduce junction temperatures and improve long-term device stability.
Superior Insulation for Reduced System Design Complexity
Many high thermal conductivity materials (such as copper and aluminum) offer excellent heat dissipation but fail to meet the insulation requirements of electronic devices.
Aluminum nitride wafers, while exhibiting high thermal conductivity, also possess superior insulation properties. You can achieve both heat dissipation and electrical isolation simultaneously without the need for additional insulating layers, effectively simplifying module structure and reducing assembly complexity.
Dimensionally Stable, High-Precision Thin-Sheet Machining
GORGEOUS CERAMICS (GGS) provides technical support for double-sided grinding, double-sided polishing, ultra-thin machining, laser cutting, and CNC machining. Our products boast high flatness, are less prone to cracking, and maintain consistent thickness within batches, eliminating deviations and meeting the needs of precision electronic devices such as MEMS.
Wafer-Level Surface Control, Reducing Subsequent Process Risks
GORGEOUS CERAMICS (GGS Ceramic) offers precision-ground and polished aluminum nitride wafers, free of surface particles, defects, and scratches. The superior surface and internal quality significantly reduces the risks associated with subsequent processes such as coating, metallization, and bonding.
Suitable for Various Extreme Environments, Including Vacuum
Aluminum nitride wafers exhibit excellent high-temperature resistance and chemical stability. They can withstand prolonged high-temperature environments in an inert atmosphere, and their coefficient of thermal expansion matches that of silicon.
Supports various precision machining and customization
GORGEOUS CERAMICS (GGS Ceramic) provides ultra-high precision surface finishing services to meet the stringent flatness and surface quality requirements of various semiconductor industries.
We offer surface finishing services including double-sided polishing, mirror polishing, precision grinding, and double-sided grinding.
We support various customized processing needs, providing customized services for outer diameter, thickness, surface roughness, flatness, parallelism, chamfering, edge shape, through holes, micro-holes, grooving, and CNC machining of complex structures, enabling processing according to drawings and customization to specific requirements.
Specific processing data needs to be evaluated based on wafer size, thickness, material grade, product structure, and custom drawings.
