Inconsistent Performance or Poor Lithography Results

• Issue: You're getting poor resolution, excessive line edge roughness, or inconsistent feature sizes, despite following your process recipe.
• SDS Connection: Revisit Section 10: Stability and Reactivity and Section 7: Handling and Storage. Is the photoresist stored correctly? Over time, or if exposed to improper temperatures or contaminants, its chemical properties can change. Check the expiration date. Also, review Section 8: Exposure Controls/Personal Protection. Is your cleanroom environment controlled properly? Particulate contamination or inadequate temperature/humidity control (often detailed in application notes but linked to environmental requirements mentioned in SDSs) can ruin lithography. Are you using the correct developer and post-exposure bake (PEB) conditions? While not always in the SDS, the SDS will guide you on the photoresist's stability, and poor handling (like contamination) directly impacts its response to developers and bake steps.
• Solution: Verify storage conditions and check the age of the photoresist. Ensure cleanroom environmental parameters are within specified ranges. Double-check compatibility with developers and other process chemicals mentioned in the manufacturer's technical datasheets (which complement the SDS).

Skin Irritation or Allergic Reactions

• Issue: A user experiences redness, itching, or rash after handling the photoresist.
• SDS Connection: This directly points to Section 2: Hazard(s) Identification (irritant/sensitizer classification) and Section 8: Exposure Controls/Personal Protection. Did the user wear the correct type of gloves? Not all nitrile gloves are created equal, and some solvents in photoresists can degrade certain materials quickly. Was there skin contact that wasn't immediately washed off?
• Solution: Ensure the correct chemical-resistant gloves are used (refer to manufacturer's recommendations based on the SDS). Wash affected skin immediately and thoroughly with soap and water. Seek medical attention if symptoms persist. Review handling procedures to prevent direct contact.

Unexpected Fume Exposure or Odor Issues

• Issue: A strong solvent odor is noticeable, or users report headaches or dizziness.
• SDS Connection: This relates to Section 2: Hazard(s) Identification (flammability, health hazards from vapors) and Section 8: Exposure Controls/Personal Protection. The photoresist likely contains volatile organic compounds (VOCs). Is the ventilation system (fume hood, local exhaust) functioning correctly and performing within specifications? Was the container left open for too long?
• Solution: Immediately stop work and ensure proper ventilation is restored. If symptoms are severe, evacuate the area and seek fresh air. Check fume hood performance logs. Ensure containers are sealed tightly when not in use. If the problem persists, consult the manufacturer or safety officer about potential off-gassing issues or required respiratory protection.

Spills and Cleanup Difficulties

• Issue: A spill occurs, and the cleanup materials aren't effective, or the process is messy and hazardous.
• SDS Connection: Section 13: Disposal Considerations and Section 7: Handling and Storage are key, but also Section 4: First-Aid Measures (for immediate exposure during cleanup) and Section 8: Exposure Controls/Personal Protection (for PPE during cleanup). Did you have the right absorbent materials for organic solvents? Was PPE adequate during cleanup? Was disposal handled according to regulations?
• Solution: Maintain a well-stocked chemical spill kit appropriate for organic solvents. Ensure personnel are trained on spill response procedures outlined in the SDS. Dispose of absorbed waste as hazardous waste according to local regulations. Clean the area thoroughly.

Incompatibility Issues

• Issue: Unexpected reactions, degradation, or haziness observed when AZ nLOF 2035 is mixed or stored near other chemicals.
• SDS Connection: This is directly addressed in Section 10: Stability and Reactivity, which lists incompatible materials. It's also indirectly covered in Section 7: Handling and Storage regarding segregation.
• Solution: Carefully review Section 10 of the SDS for AZ nLOF 2035 and the SDSs of any other chemicals being used in proximity. Store incompatible materials separately. Ensure thorough cleaning of equipment between uses of different chemicals to prevent cross-contamination.

By proactively considering these potential issues and linking them back to the information provided in the SDS, you can prevent many problems before they start and address them effectively when they do occur. Remember, the SDS is a dynamic tool – refer back to it often!
