Specific uses of CVD SiC coated dummy wafers：

● Versatile testing and experimentation: SiC coated dummy wafers are essential at all stages of semiconductor production, providing a safe and reliable means of testing and experimentation. They are essential at the beginning of the production process, ensuring that all parameters are optimal before the valuable production wafers are used.

● Protection during diffusion: During the diffusion process, dummy wafers play a vital role by shielding standard silicon wafers. This protective function prevents damage and contamination, thereby maintaining the integrity and quality of the original wafer.

● Measurement accuracy: These wafers are carefully used to measure film thickness, pressure resistance, and reflective index. They also help detect the presence of pinballs and evaluate pattern dimensions in lithography, making a significant contribution to process accuracy and defect reduction.

In fact, VeTek Semiconductor supports customized product services and can provide user-defined serialization on each CVD SiC coating dummy wafer according to customer needs, allowing for customized size and thickness. Custom laser engraving further eliminates the risk of cross contamination, ensuring a high degree of purity and reliability.
