Specification of High Thermal Conductivity Aluminum Nitride Ceramic Substrate for Semiconductor Industry

This Aluminum Nitride ceramic substrate is for the semiconductor industry. It handles high heat extremely well. Heat management is critical in electronics. Components generate a lot of heat. This heat must go away fast. Otherwise parts get too hot. Overheating damages components. Performance drops. Reliability suffers. This AlN substrate moves heat efficiently.

Its thermal conductivity is very high. This number measures how easily heat travels through the material. Higher is better for cooling. Our AlN offers thermal conductivity up to 180 W/mK. That’s much better than regular alumina. Alumina is around 25 W/mK. AlN spreads heat fast. This keeps device temperatures lower. It prevents hotspots.

The thermal expansion coefficient is important too. It matches silicon chips well. Silicon chips expand when hot. The substrate expands too. Different expansion rates cause stress. Stress cracks the chip or the substrate. AlN expands at a rate close to silicon. This reduces stress problems. It makes the bond stronger. Reliability improves.

Electrical insulation is another key feature. The substrate must not conduct electricity. It isolates the circuit. AlN is an excellent electrical insulator. It has high electrical resistance. Voltage breakdown strength is high. This prevents electrical shorts. It keeps the circuit safe.

Surface quality is very smooth. A smooth surface is needed. Components attach directly sometimes. Thin films deposit onto it. A rough surface causes defects. Our AlN substrates are polished finely. They have a very low surface roughness. This ensures good bonding. It allows precise patterning.

These substrates are strong. They resist breaking. They handle thermal cycling well. Heat up, cool down, repeat. Many materials fail after cycles. AlN maintains its strength. It lasts a long time. This is vital for demanding applications.

You find these substrates in power modules. Power devices create intense heat. LED packages use them too. High-brightness LEDs need cooling. RF devices benefit from AlN. Laser diodes require good heat sinking. Any application needing fast heat removal can use it. It’s the top choice for thermal management.

Applications of High Thermal Conductivity Aluminum Nitride Ceramic Substrate for Semiconductor Industry

Aluminum nitride ceramic substrates are vital in modern semiconductors. They move heat away very well. This high thermal conductivity is key. Semiconductor devices generate a lot of heat. Too much heat harms performance and lifespan. Aluminum nitride helps prevent this. It keeps things cooler and more reliable.

These substrates also stop electricity from flowing through them. They are electrical insulators. This is necessary. Circuit paths need isolation. Aluminum nitride provides this insulation effectively. It also expands and contracts similarly to silicon chips. This thermal expansion match is important. It reduces stress. It prevents cracking or warping during temperature changes. This improves manufacturing yield.

One major use is in high-power LEDs. Bright LEDs create significant heat. Aluminum nitride substrates draw this heat out fast. They protect the delicate LED chips. They allow brighter light and longer life. Power electronics also depend on these substrates. Devices like IGBTs and MOSFETs handle high currents. They get very hot. Aluminum nitride baseplates manage this heat efficiently. They enable smaller, more powerful modules.

Laser diodes need precise thermal control. Aluminum nitride substrates are perfect here. They quickly remove heat from the laser junction. This keeps the wavelength stable. It prevents damage. Radio frequency devices benefit too. RF components are sensitive to temperature shifts. Aluminum nitride maintains stable operating conditions. It ensures consistent signal quality. The material is also strong mechanically. It resists wear and chemicals. This durability is valuable in demanding semiconductor environments.
