Semiconductor Wafer Carrier Alumina Disk and Ceramic Edge Ring



High precision ceramic components improve yield management for semiconductor wafer processing. Innovacera ceramic components provide precise dimensional stability, ultra-flatness and smoothness, and vacuum holding of wafers during inspection and processing. Low-surface-contact configurations minimize risk of back-side particles negatively affecting wafer geometry for precision applications.

Semiconductor Wafer Carrier Disk
The main features of high precision ceramic parts:

Alumina Wafer Carrier
1. Wear and abrasion resistance: Alumina is a tough technical ceramic with very good wear resistance.
2. High precision dimensions with tightening tolerance, it easier to get a perfect fitting relationship.
3. Chemical inertness, resistant to most of the strong acids and alkalis.
4. High-temperature ability: withstand up to 1600°C in oxidizing and reducing atmospheres.
5. Great mechanical properties, hardness, compressive, and flexural strength are much higher in stainless steel.
6. Electrical insulation: The insulation breakdown is 20KV at least.
7. Protective atmospheres or high vacuum at high temperatures to eliminate contamination or impurity.
8. Chemical corrosion resistance under high temperatures, even with strong acid or alkali.
9. Low material cost in high-level applications than other technical ceramics.

Source: https://www.innovacera.com/news/ceramic-heater-coil-for-vaporizer.html Not every dry herb vaporizers are the same! Especially those used ceramic heating element. The ceramic heating element is a safety and healthiest option for dry herb vaporizers, so every vaper is preferred to choose those vaporizers that carry ceramic heating element. The proponents believe that the heating element is the core of the vaporizer and primarily dictates the experience of the taste. Let's more specific, when a vaper burns tobacco, marijuana, or hemp during traditional smoking to release the active component, whatever it's nicotine, CBD, or THC, they inhale the smoke. We all know that's not good for health. Rather than burning, Vaporizer heats the liquid, wax or even dry herb to release a vapour, and a vaper inhales the vapour without any damage to their lungs or throat. And why the ceramic heating element is becoming the core part of the vaporizer? It's mainly because: 1. Ceramic

BAN combines  Aluminum Nitride with Boron Nitride , a hybrid machinable Aluminum Nitride ceramic with excellent thermal conductivity, high strength, and resistance to thermal shock. Innovacera provides BAN, and it has very similar properties to SHAPAL material. SHAPAL is a trademark of Tokuyama Corporation.   These ceramics are used in various industries, including electronics, semiconductor manufacturing, aerospace, automotive and medical. BAN ceramics have properties that make them suitable for applications such as  heat sinks , heater substrates, semiconductor processing components, and optical equipment.   Material Advantages : High mechanical strength. High thermal conductivity. Low thermal expansion. Low dielectric loss. Excellent electrical insulation. High corrosion resistance–non-wetted by molten metals. Excellent Machinabilit–BAN can be machined to high-precision complex shapes. It has excellent sealing ability to vacuum and hasn’t given off much gas. High-frequency wave prop
