Parameters of Advanced Diamond Suspension for silicon carbide substrate thinning with good TTV and Ra
Diamond suspension is an advanced technology used in the thinning of silicon carbide substrates, particularly in the field of photolithography. It uses diamond particles to create a smooth surface on the substrate, resulting in improved, reduced coefficient of thermal expansion, and lower resistivity.
In order to achieve good TTV (temporal thermal variance) and Ra (resistivity) parameters, the diamond suspension process typically involves several steps:
1. Preparation of the substrates: The substrates are cleaned, sanded, and etched to remove any foreign materials or unwanted features.
2. Deposition of the diamond suspension: A suspension of diamonds is applied to the substrate using a chemical vapor deposition (CVD) process. This involves exposing the substrate to a high-temperature gas (such as oxygen or nitrogen) and causing it to vaporize the diamonds onto the substrate.
3. Surface finish: Once the diamond suspension has been deposited, it is typically polished to create a smooth surface. This can be done using various techniques such as wet sanding or dry polishing.
4. Characterization: After the final step, the diamond suspension may be characterized using various techniques such as X-ray diffraction (XRD), transmission electron microscopy (TEM), or scanning tunneling microscopy (STM).
5. Optimization: Based on the results of the characterization, the process parameters can be optimized to further improve the thinning performance of the diamond suspension.
Overall, the use of diamond suspension in silicon carbide thinning offers several advantages over traditional methods, including improved efficiency, reduced coefficient of thermal expansion, and lower resistivity. However, the specific process parameters that result in the best performance will depend on the details of the equipment and the desired application.
