Overview of Semiconductor Used Customized Mirror Polish Aluminum Nitride Plate Ain Ceramic Disc Wafer

Aluminum Nitride Ceramic is an advanced ceramic material with aluminum nitride as the main component. It has been widely used in electronics, optics, and mechanics due to its unique properties.

Features of Semiconductor Used Customized Mirror Polish Aluminum Nitride Plate Ain Ceramic Disc Wafer

High thermal conductivity: Aluminum nitride ceramics have relatively high thermal conductivity, usually between 170-260 W/m·K, which makes it an excellent heat dissipation material. It is especially suitable for electronic devices that require efficient heat dissipation, such as substrate materials for power semiconductor devices.

Good electrical insulation: Despite its high thermal conductivity, aluminum nitride ceramics are excellent insulators of electricity, which can effectively prevent current leakage and ensure the safe operation of electronic components.

Low dielectric constant and dielectric loss: These characteristics make aluminum nitride ceramics very suitable for use in high-frequency circuits because it can reduce energy loss during signal transmission.

High temperature resistance: Aluminum nitride ceramics can maintain structural stability and strength at extremely high temperatures. Its melting point is about 2800°C, so it is suitable for applications in high temperature environments.

Low thermal expansion coefficient: Compared with semiconductor materials such as silicon, aluminum nitride has a lower thermal expansion coefficient, which means it has better dimensional stability when the temperature changes, which helps improve packaging reliability.

Corrosion resistance: Aluminum nitride ceramics have good chemical stability to most molten metals and are not easily oxidized or corroded, allowing them to perform well in harsh environments.

High mechanical strength: Although not as hard as some other types of ceramic materials, aluminum nitride ceramics still provide enough mechanical strength to allow them to be used in many structural applications.

Applications of Semiconductor Used Customized Mirror Polish Aluminum Nitride Plate Ain Ceramic Disc Wafer

Semiconductor manufacturing needs precision parts. Customized mirror polish aluminum nitride ceramic discs serve this purpose. These AlN plates handle extreme conditions inside chip making tools. Their thermal conductivity is very high. Heat moves away from sensitive components fast. This prevents overheating damage. Temperature stability matters too. AlN plates keep their shape and size across large temperature swings. Electrical insulation is another key benefit. They stop stray currents from interfering with delicate processes. Chemical resistance is strong. AlN withstands harsh chemicals used in etching and cleaning steps.

The mirror polish surface is critical. It achieves an ultra-smooth finish. This flatness is near perfect. It prevents particle traps or scratches on silicon wafers. Tiny defects ruin chips. The smooth surface minimizes contamination risk. Cleanliness is non-negotiable in fabs. Customization options are important. Manufacturers can specify exact disc dimensions. Thickness, diameter, and hole patterns are tailored. This ensures a perfect fit inside specific equipment chambers. The material is also mechanically robust. It resists chipping and cracking during handling.

These AlN ceramic wafers are vital in many semiconductor tools. They work well as heater plates. Uniform heating is essential for processes like CVD and PVD. They act as electrostatic chucks (ESCs). ESCs hold wafers firmly using electric force during lithography or etching. They serve as insulative spacers. This isolates different tool sections electrically. They are substrates for thin film deposition. Their stability supports precise layer growth. Process reliability improves significantly. Yield rates go up.

5 FAQs of Semiconductor Used Customized Mirror Polish Aluminum Nitride Plate Ain Ceramic Disc Wafer

What makes mirror polishing important for Aluminum Nitride plates?
Mirror polishing creates an ultra-smooth, flat surface. This flatness is critical. It ensures maximum contact between the plate and other components. Better contact means heat transfers much more efficiently. Heat moves easily away from sensitive parts. This prevents overheating and boosts device performance. Rough surfaces trap air gaps. Air gaps block heat flow.

Can I get specific sizes and thicknesses?
Yes. We customize plates to your exact needs. Common diameters range from 10mm to 150mm. Thickness typically spans 0.3mm to 3.0mm. Tell us your required diameter, thickness, and tolerance. We manufacture it precisely. We handle small prototypes and large production runs.

How well does Aluminum Nitride conduct heat?
Aluminum Nitride (AlN) excels at heat conduction. Its thermal conductivity is very high, around 170-180 W/mK. This is much better than alumina ceramic. It moves heat roughly ten times faster than steel. This makes AlN ideal for high-power electronics. It keeps circuits cool effectively. Efficient heat dissipation extends device lifespan.

Is this material durable?
Yes, AlN ceramic is strong. It resists wear and corrosion well. It handles high temperatures reliably. The mirror polish itself is hard. It resists scratches under normal use. Handle these plates carefully. Avoid dropping them or hitting edges. The material can chip if impacted sharply. Proper handling prevents damage.

Are there special handling needs?
Handle mirror polished AlN plates with clean gloves. Oils and dirt from skin can mar the surface. Place the plates on soft, clean surfaces. Avoid dragging them across hard materials. Protect the polished face from scratches. Store them carefully. Avoid stacking plates directly on each other. Use protective separators. This keeps the surface flawless for your application.
