Developer & Rinse Ancillary Products
Photosensitive Process
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.
| 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. |
| PA-400R | The preferred rinse is based on PGMEA. |
