AZ 400K Developer
Overview
The AZ 400K Developer is a potassium based buffered developer. It is an odorless, aqueous, inorganic, alkaline solution designed to achieve high contrast and wall profile with photoresists at high coating thicknesses, especially AZ 4500 and P 4000 series photoresists. It has excellent batch-to-batch consistency.
Features
- Minimized contamination risks due to use of less mobile potassium ions
- Excellent batch-to-batch consistency
- High throughput and contrast for thick film photoresists
- Buffered for uniform pH, maximum bath life and process stability
Hazards
- Severe eye irritation
- Non-irritating to skin
- Noncombustible
- Some evidence of affect on fertility (see SDS)
Safety
- Avoid contact with eyes, especially through mist
- Wash skin thoroughly after handling
- Wear chemical resistant eye protection, protective gloves and clothing
