Developers & Rinses

Developers & Rinses for Photosensitive Polyimides

HD MicroSystems™ produces solvent based, ancillary products for its line of negative tone photosensitive polyimides. This includes the HD-4100 Series products. Typical use is a 20:1 ratio of developer to polyimide (for example, a 250g bottle of HD-4100 will require about one gallon of developer). Requirements for rinse are about a 10:1 ratio.

All ancillary products are filtered to 0.2µm and tested for metal impurities, typically well below 500ppb.

 Developers
PA-400D
Based on gamma butyrolactone (BLO) this developer is more aggressive to develop faster but may not exhibit the process latitude of the PA-401D.  
PA-401D
The standard developer for the HD-4000 Series products. Based on cyclopentanone (CPO) it offers an evenly controlled develop rate and can be used as an edge bead remover, as well.
 Rinses
PA-400R
The preferred rinse is based on PGMEA.
