PR1-4000A
Positive Resist PR1-4000A is a positive tone photoresist designed for 365 or 436 nm wavelength
exposure, using tools such as wafer steppers, scanning projection aligners, proximity printers and
contact printers. PR1-4000A excels in applications when superior adhesion is required. Use of
adhesion promoters, such as HMDS is not recommended with PR1-4000A.
These are the advantages of PR1-4000A over other resists:
- superior resolution capability
- fast photospeed
- superior linewidth control due to suppression of reflective notching
- substrate adhesion which is superior to that of any commercial positive resist
- ease of removal after RIE process
- shelf life exceeding 1 year at room temperature storage.
The formulation and processing of PR1-4000A were designed with regard to occupational and
environmental safety. The principal solvent in PR1-4000A is 1-methoxy-2-propanol and
development of PR1-4000A is accomplished in a basic water solution.
