AMAT 0130-72336
- Product Name: AMAT 0130 – 72336 Semiconductor Process Chamber Heating Zone Insulation
- Product Introduction: In semiconductor process chambers, maintaining proper temperature distribution is essential for the success of various thermal – based processes. The heating zone insulation is used to minimize heat loss from the heating elements and ensure that the heat is directed towards the wafer, improving process efficiency and temperature uniformity.
- Technical Specifications:
- Material: Made from high – temperature – resistant and low – thermal – conductivity materials such as ceramic fibers, graphite felt, or refractory bricks.
Detailed content
-
- These materials can withstand high temperatures, typically up to 1000°C or more, and have low thermal conductivity to reduce heat transfer to the surrounding environment.
- Thickness: The thickness of the insulation is designed based on the heat loss requirements and the available space in the process chamber. Thicker insulation provides better heat insulation but may take up more space, while thinner insulation may be suitable for applications where space is limited.
- Thermal Conductivity: Has a very low thermal conductivity, usually in the range of 0.02 – 0.2 W/(m·K) at high temperatures. This low thermal conductivity helps to keep the heat within the heating zone and prevent it from escaping to the chamber walls or other non – heating areas.
- Functional Features:
- Heat Retention: Effectively retains heat within the heating zone, reducing the energy consumption required to maintain the desired process temperature. This also helps to improve the temperature stability of the process chamber, which is crucial for processes that require precise temperature control.
- Thermal Shock Resistance: Can withstand rapid temperature changes without cracking or degrading. In semiconductor processes, the heating and cooling cycles can be frequent, and the insulation must be able to handle these thermal shocks to ensure long – term reliability.
- Easy Installation and Maintenance: Designed for easy installation and removal in the process chamber. This allows for quick replacement in case of damage or wear and facilitates maintenance activities such as cleaning or inspection of the heating elements.
- Application Scenarios: Installed around the heating elements in semiconductor process chambers. It is used in various processes such as annealing, where precise temperature control is necessary for the proper activation of dopants and stress relief in the wafer. In chemical vapor deposition (CVD) processes, it helps to maintain a uniform temperature across the wafer surface for consistent thin – film deposition.
