Product information "AZ 12XT-20PL-15 Photoresist - 3.785 l"
AZ® 12XT-20PL-15
Chemically Amplified Positive Tone Photoresists
General Information
AZ® 12XT is a chemically amplified, i-line sensitive thick photoresist for high aspect ratios and with an increased thermal softening point.
AZ® 12XT - 2.4mm lines at 10mm film thickness
Product Features
AZ® 12XT covers a resist film thickness range of approx. 5 - 20 µm. As a chemically amplified resist, the AZ® 12XT does not require rehydration between softbake and exposure, requires significantly lower exposure doses compared to non-chemically amplified resists of comparable thickness, does not release nitrogen during exposure (no bubble formation in the resist film during exposure), and has very high development rates for a thick resist. These properties help to make the entire process significantly faster and less prone to problems than with non-chemically amplified thick resists. Its good adhesion to all common substrate materials and its potential for steep resist sidewalls make it suitable for galvanic molding, and its high thermal softening point (approx. 130 °C) also recommends it for dry etching or DRIE. Basically, the AZ® 12XT is only sensitive to i-line, but with correspondingly high exposure doses and resist film thicknesses, the h-line (405 nm) can also be used. If resist film thicknesses of less than approx. 5 µm are required, the AZ® 12XT can easily be diluted with PGMEA = AZ® EBR Solvent. For resist film thicknesses greater than 15 µm, the chemically amplified AZ® IPS 6090 should be considered.
Developers
TMAH-based developers such as the ready-to-use AZ® 326 MIF or AZ® 726 MIF are recommended for developing this chemically amplified photoresist. KOH- or NaOH-based developers such as the AZ® 400 K or AZ® 351B are less suitable for the AZ® 12 XT.
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 isopropanol) 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
If the resist is to be diluted for spin coating, PGMEA = AZ® EBR Solvent is an option. PGMEA is the solvent for AZ® 12 XT anyway and is also recommended for edge wall removal if necessary.
