Product information "AZ 1505 Photoresist - 3.785 l"
AZ® 1505
Positive Thin Resists for Wet Etching
General Information
The AZ® 1505 Photoresist belongs to the AZ® 1500 Photoresist Series of positive thin resists (g-, h- and i-line sensitive) with optimized adhesion to all common substrate materials, the main application of which is as a resist mask for wet etching.
Product Properties
AZ® 1500 Resist Family is not optimized for very steep resist sidewalls nor for high stability against thermal softening (softening temperature approx. 100 °C), but for improved adhesion to all common substrate materials. The high photoinitiator concentration of the AZ® 1500 Photoresist Series compared to thick resists allows for very fast development. AZ® 1505 Photoresist is the thinnest member of the AZ® 1500 Photoresist Series with a resist film thickness of approx. 500 nm at 4000 rpm. This resist is often used for chrome etching in photomask production, but is also suitable as an etching mask for other materials. AZ® 1505 allows a resolution in the submicrometer range under optimized process parameters. If such a high resolution is not required, a slightly thicker resist (for example AZ® 1514 H Photoresist or AZ® 1518 Photoresist) can be useful, which reduces the risk of pinholes in the resist film caused by particles on the substrate and the corresponding etching defects. Further dilution of the AZ® 1505 is not recommended, as heavily diluted, photoinitiator-rich resists tend to quickly form particles. If the resist does have to be diluted, the corresponding batches should be used up quickly and attention should be paid to possible particle formation.
Developers
For development, we recommend either TMAH-based developers such as AZ® 326 MIF or AZ® 726 MIF, the NaOH-based AZ® 351B, and if the requirements for selectivity are not too high, the KOH-based AZ® 400K. With AZ® 351Bor AZ® 400K, it may be advisable to work with a higher diluted developer (for example 1:5 to 1:6) instead of the usual 1:4 dilution to achieve very fine resist structures or better controllable development times. On alkaline-sensitive substrate materials such as aluminum, we recommend the aluminum-compatible AZ® Developer in a 1:1 dilution.
Removers
If the resist structures have not been thermally cross-linked by plasma processes, ion implantation or high temperatures (> approx. 140°C), all common removers such as AZ® 100 Remover, DMSO or many other organic solvents (e.g. acetone rinsed with isopropyl alcohol) are suitable for removing the resist layer. For cross-linked resist structures, high-performance strippers such as the NMP-free TechniStrip P1316 or AZ® 920 Remover are recommended, and in the case of alkaline-sensitive substrate materials (such as aluminum), the TechniStrip MLO 07.
Thinning/ Edge Bead Removal
Even if, as described above, further dilution of AZ® 1505 Photoresist is not recommended due to the accelerated particle formation, PGMEA = AZ® EBR Solvent is the recommended solvent. PGMEA is the solvent for AZ® 1505 anyway and is also recommended for edge wall removal if necessary.
