Negative Resists NR1, NR5, NR7 and NR9 series and Positive Resist PR1 series.
Properties
♦ Principal solvent: water
♦ Tetramethylammonium hydroxide content (%): 2.25-2.30
♦ Appearance: clear liquid
♦ Specific gravity at 25°C (g/cm³): 0.99-1.01
♦ Guaranteed shelf life at 25°C storage (years): 3
Processing
1 Pour the developer solution into the resist development tank.
2 Establish that the temperature of the developer is correct.
3 Develop the resist by immersion or spraying, following the instructions in the ‘processing’
section of the technical information for the resist.
4 Rinse the substrate in deionized water until the water resistivity reaches the prescribed
limit.
