Features of TC Wafer
Embedded Thermocouples:
TC wafers have thermocouples embedded at various points to provide accurate and real-time temperature measurements across the wafer surface.
High-Temperature Range:
These wafers can withstand and accurately measure a wide range of temperatures, which is critical for processes that involve high temperatures.
Uniformity Measurement:
TC wafers help in assessing temperature uniformity across the wafer, which is crucial for ensuring consistent process results and high-quality semiconductor devices.
Real-Time Monitoring:
They provide real-time temperature data, enabling process engineers to make immediate adjustments to maintain optimal conditions during manufacturing.
Calibration and Process Control:
TC wafers are used for calibrating temperature settings in semiconductor equipment, ensuring that the actual temperatures match the setpoints.
Compatibility with Process Equipment:
Designed to be compatible with standard semiconductor processing equipment, allowing for seamless integration into existing workflows.
Durability and Reusability:
Made to be durable and reusable, TC wafers can undergo multiple cycles of high-temperature processes without significant degradation.
Benefits of TC Wafer

Facilitates the development and fine-tuning of new processes by providing detailed temperature profiles.
Chemical Vapor Deposition (CVD):
Ensuring uniform temperature distribution during the deposition of thin films.
Etching:
Monitoring and controlling the temperature during plasma etching to achieve precise patterning.
Annealing:
Measuring temperatures during annealing processes to ensure proper activation of dopants and stress relief in the wafer.
Rapid Thermal Processing (RTP):
Providing accurate temperature profiles during rapid heating and cooling cycles.
Oxidation:
Controlling the temperature during oxidation processes to form high-quality oxide layers on the wafer surface.
Epitaxy:
Ensuring temperature consistency during the growth of epitaxial layers.
Physical Structure and Material Composition of TC Wafer
Substrate Material: Typically, the same material as the production wafer is used, such as silicon, sapphire, or silicon carbide, to ensure matching thermal expansion coefficients and avoid stress caused by temperature changes that could affect measurement accuracy. The choice of substrate material depends on the specific application scenario; for example, silicon substrates are suitable for most integrated circuit processes, while sapphire and silicon carbide are more suitable for high-temperature and special application environments.
Sensor Network: Distributed on the wafer surface in the form of a thermocouple array, commonly using K-type thermocouples (chromel-alumel alloy). The junction size is extremely small (wire diameter only 0.127-0.254mm), forming a uniformly distributed array centered around the wafer. These miniature thermocouples are fixed at specific positions on the wafer using high-precision welding processes. For large 300mm (12-inch) wafers, the sensor position accuracy needs to be controlled within ±50μm to ensure the accuracy of the temperature distribution map.
Signal Transmission System: Includes high-temperature resistant cables (usually wrapped in alumina ceramic fiber sleeves) and vacuum feedthroughs (polyimide flat cables), ensuring stable transmission of temperature signals in ultra-high vacuum environments of 10⁻⁷ Torr and extreme temperature conditions.
Features of TC Wafer
Real-time temperature monitoring:
Obtains real-time temperature measurements at key locations on the wafer surface, as well as the overall temperature distribution of the wafer.
Transient temperature analysis:
Continuously monitors the transient temperature changes of the wafer during the heat treatment process, such as heating, cooling, and dwell periods, providing critical data support for process optimization.
Operating Procedure Precautions
TC Wafer sensor are functioning correctly, and perform maintenance and calibration to ensure measurement accuracy.
Clean the wafer surface and check for damage or residual foreign matter; if a support or carrier is needed, ensure proper alignment.
Preheating Treatment: Preheat the wafer before testing to ensure uniform surface temperature.
Parameter Settings: Set annealing temperature, time, atmosphere, and other parameters according to the wafer material and processing requirements, and select the appropriate measurement mode.
Real-time Monitoring and Recording: Closely monitor the measurement results, avoiding shaking the sensor or wafer; record measurement time, location, and other information for subsequent analysis.
Wear protective gloves and safety glasses throughout the operation; turn off the equipment according to operating instructions after testing.
Clean and maintain the equipment to ensure long-term stable operation; wait for the wafer to cool before handling to avoid temperature shock affecting quality.
