Semiconductors Applications
Main Challenges of Non-Contact Temperature Measurement in the Semiconductor Industry
Infrared (IR) non-contact temperature measurement presents specific challenges in the semiconductor industry. One major challenge is emissivity variation across different semiconductor materials. In processes like Physical Vapor Deposition (PVD) and Chemical Vapor Deposition (CVD), the varying emissivity of substrates and thin films can affect the accuracy of IR temperature readings. Proper calibration is essential to account for these differences, as inaccuracies can lead to suboptimal process control and compromised quality.
Another challenge involves thermal gradients and temperature uniformity in high-precision processes such as polysilicon production and rapid thermal annealing. Semiconductor wafers and components often experience uneven heating, which IR sensors must detect accurately. The complexity of managing these gradients requires advanced IR technology capable of high-resolution thermal imaging and precise temperature monitoring to maintain consistent quality.
Ambient heat interference and reflective surfaces also impact the accuracy of IR measurements. In processes like lithography and the strip and clean process, managing thermal interference from surrounding equipment and reflective surfaces is critical. Effective shielding and careful sensor placement are necessary to ensure reliable temperature readings and process integrity.
Benefits of Using IR Non-Contact Temperature Measurement in Semiconductor Manufacturing
Despite these challenges, IR non-contact temperature measurement offers substantial benefits in enhancing quality in the electronics industry. In Physical Vapor Deposition (PVD) and Chemical Vapor Deposition (CVD), IR sensors provide precise thermal monitoring, ensuring uniform coating of semiconductor wafers. This precision helps in achieving the desired film thickness and quality, directly impacting the performance and reliability of electronic components.
For polysilicon production and rapid thermal annealing, IR technology ensures optimal temperature control during critical thermal processing. Accurate temperature management prevents defects and inconsistencies in polysilicon layers, which are crucial for producing high-quality semiconductor devices. This leads to improved product yield and performance.
Lithography and strip and clean processes also benefit from IR temperature measurement. During lithography, maintaining the correct temperature in exposure systems ensures pattern accuracy and reduces defects. In the strip and clean process, IR sensors help manage temperatures to effectively remove photoresists and other materials, ensuring consistent processing and high-quality outcomes.
