Specification of AIN bar Aluminium Nitride Ceramic Rods for Semiconductor

Here are the specs for our AIN bar Aluminium Nitride Ceramic Rods. These rods are built for demanding semiconductor work. They handle intense heat effectively. Their thermal conductivity is very high. Expect values between 170 and 200 W/mK. This moves heat away from sensitive components fast. The rods provide excellent electrical insulation. They stop electrical leaks reliably. Their volume resistivity is greater than 10^14 Ω·cm. This ensures safe operation in electronic circuits.

Aluminium Nitride is very stable chemically. It resists attack from many process chemicals. This includes common acids and bases. The material doesn’t corrode easily. This means long life in harsh fab environments. Its mechanical strength is good. It withstands physical stress well. Flexural strength typically exceeds 300 MPa. The material is also quite hard. Its Vickers hardness is around 1200 HV. This prevents surface damage.

Thermal expansion is a critical factor. AIN’s coefficient matches silicon closely. This prevents stress cracks during heating cycles. Dimensional stability is excellent. The rods stay put under thermal load. We offer standard diameters like 3mm, 5mm, 10mm, 15mm, 20mm. Tolerances are tight. Diameter tolerance is usually ±0.05mm. Straightness is controlled within 0.5mm per 100mm length. Standard lengths are 100mm, 200mm, 300mm. Custom lengths are possible. Surface finish is smooth. Typical Ra is better than 0.4μm. This minimizes particle generation.

Purity levels are high. The AlN content is greater than 99%. Oxygen content is kept low. This maximizes thermal performance. Trace metal impurities are minimized. This prevents contamination in sensitive processes. These rods are machined precisely. They fit precisely into semiconductor equipment. They serve as heater stands, wafer supports, insulators. They are essential for thermal management. Their performance is consistent. Reliability is proven in production.

Applications of AIN bar Aluminium Nitride Ceramic Rods for Semiconductor

Aluminium Nitride ceramic rods are vital in semiconductor manufacturing. They handle extreme heat well. They move heat away from sensitive parts effectively. This prevents overheating. Semiconductor tools get very hot during operation. These rods keep temperatures stable. Stable temperatures mean better process control. Better control improves chip yield and quality.

Electrical insulation is another key benefit. These rods do not conduct electricity. They separate high-power components safely. This prevents short circuits. Short circuits ruin expensive equipment. Semiconductor tools need reliable electrical isolation. Aluminium Nitride provides it perfectly.

These rods also resist chemical attack. Harsh gases and plasmas are common in chip fabs. Aluminium Nitride withstands these environments. It doesn’t degrade easily. This means longer life for furnace parts, plasma chambers, and wafer chucks. Downtime costs money. Longer part life saves money.

The material matches silicon in thermal expansion. Silicon wafers expand with heat. So do these rods. They expand at nearly the same rate. This prevents stress cracks. Cracks ruin wafers and tools. Matching expansion protects delicate silicon structures. It ensures dimensional stability during rapid heating and cooling cycles.

Manufacturers use AIN rods in many critical tools. You find them in wafer chucks holding silicon during processing. They are essential in heaters for precise temperature zones. They serve as insulators in high-power RF components. Plasma etch and deposition chambers rely on their plasma resistance. Susceptors for epitaxial growth need their thermal properties. Semiconductor testing equipment uses them for thermal management.

5 FAQs of AIN bar Aluminium Nitride Ceramic Rods for Semiconductor

Here are 5 FAQs about our AIN bar Aluminum Nitride Ceramic Rods for Semiconductor:

What do these Aluminum Nitride rods do in semiconductor tools?
These rods position wafers. They hold silicon wafers during processing steps like etching or deposition. They need to handle extreme heat and harsh chemicals without contaminating the wafer.

Why is Aluminum Nitride (AlN) the right material for these rods?
Aluminum nitride offers key advantages. It moves heat away fast. This stops parts from overheating. It also blocks electricity completely. This prevents electrical shorts. It resists chemical attack from common process gases and plasmas. It stays strong at high temperatures.

How well do these rods handle heat?
Aluminum nitride moves heat very effectively. Its thermal conductivity is high, similar to some metals. This pulls heat away from the wafer and the tool parts quickly. Stable operation needs this. It prevents damage from overheating.

Are these rods safe around electricity?
Yes. Aluminum nitride is an excellent electrical insulator. Electricity does not flow through it. This is critical. It prevents stray currents from damaging sensitive wafers. It keeps the process environment electrically safe. High voltage situations need this insulation.

Will these rods last a long time in the machine?
Yes. Aluminum nitride is very hard and durable. It resists wear from constant handling. It handles rapid temperature changes well. It doesn’t crack easily. This toughness means less downtime for replacements. Machines run longer.
