General Information

Compared to the AZ® 4500 series, the AZ® 9200 resists have a lower optical absorption. This simplifies the exposure of (also very) thick resist films. Therefore – in combination with the missing g-line sensitivity – the AZ® 9200 series needs a higherexposure time under broadband condition, and reveals a lower development rate ascompared to AZ® 4500 films processed under the same conditions.

For lower resist film thicknesses we recommend a dilution with PGMEA = ‘AZ® EBR Solvent’. The following resist filmthicknesses refer to 4000 rpm understandard conditions:

  • 4.0 µm:100 g AZ® 9260 + 13 g PGMEA
  • 3.0 µm:100 g AZ® 9260 + 23 g PGMEA
  • 2.0 µm:100 g AZ® 9260 + 42 g PGMEA
  • 1.5 µm:100 g AZ® 9260 + 55 g PGMEA
  • 1.0 µm:100 g AZ® 9260 + 88 g PGMEA

Development

AZ® 400K 1 : 4 or AZ® 726 MIF recommended. In case of very thick resist films, a rather strong developerconcentration such as AZ® 400K 1 : 3.5 ... 1 : 3.0 might be reasonable forrequired short development times.
