AMAT 0190-10234
- Product Introduction:
This system is designed to precisely control the temperature of semiconductor wafers during various manufacturing processes. Temperature control is a critical factor in semiconductor manufacturing as it can significantly affect process parameters such as reaction rates, film uniformity, and stress in the wafer. This system ensures that the wafer is maintained at the optimal temperature for each specific process step. - Technical Specifications:
- Temperature Range: It can control the wafer temperature in the range of – 50°C to 300°C, covering a wide variety of semiconductor manufacturing processes that require different temperature conditions.
Detailed content
-
- Temperature Accuracy: The system can achieve a temperature accuracy of ±0.1°C, which is essential for processes that are highly sensitive to temperature variations, such as chemical vapor deposition and epitaxial growth.
- Heating and Cooling Elements: It uses a combination of resistive heating elements and thermoelectric coolers (TECs) for heating and cooling the wafer. The resistive heating elements provide rapid heating, while the TECs offer precise and local cooling capabilities.
- Functional Features:
- Multi – Zone Temperature Control: The wafer is divided into multiple zones, and each zone can be independently controlled for temperature. This allows for compensating for any temperature gradients across the wafer surface, ensuring uniform temperature distribution.
- Real – Time Temperature Monitoring: The system is equipped with multiple high – precision temperature sensors placed at different locations on the wafer and the heating/cooling elements. These sensors continuously monitor the temperature and provide real – time feedback to the control system for adjustments.
- Software Interface: It has a user – friendly software interface that allows operators to set the desired temperature profiles for different processes. The software also provides data logging and analysis functions, enabling process optimization and troubleshooting.
- Application Scenarios:
- Chemical Vapor Deposition (CVD) Processes: In CVD, the temperature of the wafer affects the deposition rate and the quality of the deposited film. This temperature control system ensures that the wafer is at the right temperature for the chemical reactions to occur uniformly, resulting in high – quality thin films.
- Epitaxial Growth: During epitaxial growth, where a single – crystal layer is grown on the wafer, precise temperature control is crucial for obtaining a defect – free and high – quality epitaxial layer. The system can maintain a stable temperature throughout the growth process, which can take several hours.
