负性光刻胶NR9-6000PY

NR9-6000PY
Negative Resist NR9-6000PY is a negative tone photoresist designed for 365 nm wavelength
exposure, using tools such as wafer steppers, scanning projection aligners, proximity printers and
contact printers.
After resist development NR9-6000PY exhibits a negative-sloping resist sidewall profile, which
facilitates a simple resist lift-off process.
These are advantages of NR9-6000PY over other resists:
-superior resolution capability
-fast develop time
-easy adjustment of the degree of resist undercut as a function of exposure energy
-temperature resistance of up to 100°C
-easy resist removal in Resist Remover RR5
-shelf life exceeding 3 years at room temperature storage.
The formulation and processing of NR9-6000PY were designed with regard to occupational and
environmental safety. The principal solvent in NR9-6000PY is cyclohexanone and development of
NR9-6000PY is accomplished in a basic water solution.

♦ Guaranteed shelf life at 25°C storage (years): 3
Processing
1 Application of resist by spin coating at selected spin speed for 40 s.
2 Begin dispensing Edge Bead Remover EBR2 simultaneously onto the top and bottom
surfaces of the spinning, coated substrate through nozzles 0.5-1.0 cm from the edge of the substrate as soon as edge bead forms (3-5 s after ceasing resist dispense). Stop dispensing
EBR2 5 seconds prior to completion of spin coating cycle.
3 150°C hotplate bake for 60 s. (softbake)
4 Resist exposure in a tool emitting 365 nm wavelength.
5 100°C hotplate bake for 60 s. (post-exposure bake)
6 Resist development in Resist Developer RD6 by spray or immersion. Development time for 6
μm thick film, for example, is 50 s.
7 Resist rinse in deionized water until water resistivity reaches prescribed limit.
8 Drying of resist.
9 Removal of resist in Resist Remover RR5 at room temperature.
Note: The above procedure refers to substrates, which are good conductors of heat such as silicon,
GaAs etc. Bake times need to be increased by a factor of 3.5 for substrates that are poor conductors
of heat such as glass.
Handling Precautions
Negative Resist NR9-6000PY is a flammable liquid. Handle it with care. Keep it away from heat,
sparks and flames. Use adequate ventilation. It may be harmful if swallowed or touched. Avoid
contact with liquid, vapor or spray mist. Wear chemical goggles, rubber gloves and protective
coating.
