Description
? Negative Resist NR9-1500P is a negative tone photoresist designed for 365 nm
wavelength exposure, using tools such as wafer steppers, scanning projection aligners,
proximity printers contact printers.
? These are the advantages of NR9-1500P over other resists: - superior resolution capability - fast photospeed - fast develop time - temperature resistance of up to 100°C - superior adhesion to substrates - easy resist removal in Resist Remover RR4 - shelf life exceeding 3 years at room temperature storage.
? The formulation processing of NR9-1500P were designed with regard to occupational
environmental safety. The principal solvent in NR9-1500P is cyclohexanone
development of NR9-1500P is accomplished in a basic water solution.
