Wafer Jar FAQs:
1. How to clean a wafer jar correctly?
When cleaning, use a dust – free cloth dipped in high – purity reagents (such as ultrapure water, isopropyl alcohol) to wipe, and avoid using ordinary cleaning agents. If there are stubborn stains remaining inside the jar, it can be immersed in a diluted hydrofluoric acid solution (only for corrosion – resistant materials). Finally, rinse thoroughly with ultrapure water and dry it to ensure there are no particle residues.
2. What is the sealing principle of a wafer jar?
It usually adopts O – ring seals, flange seals, or vacuum sealing structures. The O – ring seal achieves physical sealing through elastic extrusion; the vacuum seal creates a negative pressure by evacuating the air inside the jar, isolating external contaminants, and is often used for storing wafers sensitive to water vapor and oxygen.
3. Can a wafer jar be reused?
Yes, it can. But after each use, it needs to be thoroughly cleaned, tested for airtightness, and checked for any physical damage (such as scratches, cracks). If it is used for different types of wafers (such as common silicon wafers and compound semiconductors), additional cross – contamination testing is required.
4. How to choose the appropriate size of a wafer jar?
Choose according to the wafer size (such as 8 – inch, 12 – inch), storage quantity, and process requirements. Ensure that there is enough space for the wafer inside the jar to avoid contact with the jar wall; also consider the compatibility with equipment, such as whether it can fit into storage cabinets or glove boxes.
5. What are the requirements for the storage environment of a wafer jar?
The ideal environment is a cleanroom (Class 100 or higher cleanliness), with the temperature controlled at 20 – 25°C and the relative humidity < 40%. Avoid direct sunlight or proximity to heat sources to prevent material aging or wafer thermal deformation; also keep it away from organic solvents, corrosive gases, and other pollution sources.
6. What safety precautions should be taken when using a wafer jar in the laboratory?
When using it in the laboratory, wear dust – free gloves to avoid contaminating the wafers with hand grease; handle it gently to prevent the wafers from cracking due to collisions. If storing toxic or radioactive wafers, special labels should be attached, and laboratory safety procedures should be followed.
7. Can a wafer jar be used to store non - semiconductor wafer materials?
Theoretically, it can be used, but it is necessary to ensure that the materials are compatible with the jar material and there is no risk of contamination. For example, it can be used to store optical lenses, ultra – thin slices for scientific research, etc., but avoid using it interchangeably with semiconductor wafers to prevent cross – contamination.
8. How to detect the airtightness of a wafer jar?
Common methods include helium mass spectrometer leak detection, pressure decay testing, or humidity monitoring. The helium mass spectrometer leak detector determines the sealing performance by detecting the helium leakage; the pressure decay test observes the pressure change inside the jar; humidity monitoring judges whether there is water vapor penetration from the outside by recording the internal humidity over a long period.
9. What is the service life of a wafer jar?
The service life depends on the frequency of use, cleaning and maintenance conditions, and environmental conditions. Under normal circumstances, a quartz – made wafer jar can be used for 3 – 5 years, and a PFA – made one can be used for 2 – 3 years. If there is seal failure, material aging, or physical damage, it should be replaced immediately.
10. Can a wafer jar be placed in a high - temperature furnace to process wafers?
It depends on the material. A quartz – made wafer jar can withstand high temperatures, up to over 1000°C; while a PFA – made one has a lower temperature resistance, usually below 260°C and cannot be used for high – temperature processing. Before use, be sure to confirm the material’s heat resistance limit and the wafer process requirements.
11. How to disinfect a wafer jar in the laboratory?
In the laboratory, disinfection can be carried out by UV irradiation (suitable for transparent materials), plasma treatment, or fumigation with low – concentration hydrogen peroxide vapor. Avoid directly wiping with organic solvents such as alcohol to prevent residue from contaminating the wafers. If chemical disinfectants are used, rinse thoroughly and dry.
12. Is a wafer jar anti - static?
Some wafer jars add anti – static materials (such as carbon – doped PFA) or use anti – static coatings, which are suitable for storing wafers sensitive to static electricity. When purchasing, confirm whether the product has anti – static markings or parameter descriptions.
13. Can wafer jars be stacked for storage?
It is not recommended to stack them casually, especially when storing valuable wafers. Stacking may cause uneven stress on the lower jars, affecting airtightness or damaging the wafers. If space needs to be saved, use a special stacking rack and ensure uniform load – bearing and strong stability.
14. How to handle discarded wafers in a wafer jar?
Discarded wafers need to be sorted for disposal: ordinary silicon wafers can be recycled as general solid waste; wafers containing heavy metals, radioactive substances, or chemical pollutants need to be handled by professional institutions in accordance with laboratory hazardous waste management procedures, and random disposal is strictly prohibited.
15. Can a wafer jar be used in a vacuum environment?
Some wafer jars are designed to be vacuum – compatible and can be used for vacuum storage or transfer of wafers. Before use, confirm the product specifications and work with vacuum pumps, vacuum valves, and other equipment to achieve vacuum sealing, preventing wafers from being damaged by air pressure differences in a vacuum environment.
