DEVELOPER
After exposure, the subsequent resist mask is present as a latent image in the photoresist: The exposed areas differ chemically from the unexposed areas. The task of the developer is to dissolve either the exposed (for positive resists) or unexposed (for negative resists) resist areas, whereby the finished resist structures are created from the latent image .
Selection criteria for developers
First of all, it must be clarified whether metal-ion-free ( MIF) must/should be developed with ready-to-use preparations or whether metal-ion-containing ( MIC) may be developed with concentrates to be diluted.
The
next selection criterion for a developer is compatibility
with the respective photoresist (see table below) or the
substrate material used.

The schematic process sequence of the exposure (above) up to the
developed resist features (below) in the processing of positive resists
(left column), negative resists (centre) and image reversal resists
(right); the latter in two possible modes. The special features of the
attainable resist profiles are not included in this scheme.

AZ 2026 MIF Developer - 5.00 l
1002026
AZ® 2026 MIF Developer
Metal Ion-free Developers
General Information
AZ® 300 MIF, AZ® 326 MIF, AZ® 726 MIF and AZ® 2026 MIF Developers are developer formulations with 2.38 % TMAH (tetramethylammoniumhydroxide) in H2O.
The AZ® 726 MIF Developer contains additionally a surfactant for better wetting and easy to settle up of puddle development. Additionally to the wetting agent of the AZ® 726 MIF the AZ® 2026 MIF contains a scum remover for complete and scum-free removal of resist layers on the price of a slightly higher dark erosion ratio.
However, for our negative resists, such as AZ® nLof 2000 series, AZ® 15nXT series, AZ® 125nXT resists this developer shows outstanding performance. Even for a positive resist like AZ® 10XT resist it significantly reduces t-topping if this problem occurs.
AZ® 2033 MIF is 3.00 % TMAH in H2O with surfactants added for fast and homogeneous substrate wetting and further additives for removal of resist residuals (residues in certain lacquer families), but at the cost of a higher dark removal. Compared to the AZ® 2026 MIF, the normality is not 0.26 but 0.33. Thus the development rate is higher with the AZ® 2033 MIF Developer.

AZ 326 MIF Developer - 5.00 l
1000326
AZ® 326 MIF Developer
Metal Ion-free Developer
General Information
AZ® 326 MIF is a TMAH-based developer for dip or spray development, compatible with all AZ®</sup photoresists from our portfolio.
Product Features
The ready-to-use AZ® 326 MIF developer is an aqueous 2.38% TMAH solution without any additives. This makes it suitable for dip or spray development, but less for puddle development, for which the AZ® 726 MIF developer is the better choice due to its special surfactant for substrate wetting. TMAH-based developers are always used when development must be carried out metal ion free. In addition, TMAH- based developers are primarily recommended for our chemically amplified positive resists and our negative resists. For very thin resist layers (< 1 µm) or very high resolution requirements, it can be useful to dilute the AZ® 326 MIF with water (AZ® 326 MIF : water = 2:1 to a maximum of 1:1). AZ® 326 MIF attacks aluminum with an etching rate of approx. 70 nm/min. If this cannot be tolerated, the Al-compatible AZ® Developer is an alternative, which, however, is based on sodium compounds and is therefore not metal ion-free.
For standard (non chemically amplified), DNQ-based positive resists without the requirement of metal ion-free development, a KOH- or NaOH-based developer such as AZ® 400K or AZ® 351B can be considered instead of a TMAH-based developer for cost reasons. For cross-linking negative resists, AZ® 2026 MIF can prove advantageous, which promotes residue-free development with these resists through certain additives.

AZ 351 B Developer - 5.00 l
1000351
AZ® 351B Developer
Inorganic, Metal Ion Containing Developer
General Information
AZ® 351B Developer is a boric acid buffered, NaOH-based developer for non-chemically amplified positive resists.
Product Features
AZ® 351B Developer is a NaOH-based developer, particularly suitable for developing non-chemically amplified positive resists with layer thicknesses of a few µm. AZ® 351B Developer comes as a concentrate and is usually diluted 1: 4 with water. To increase selectivity, a 1: 5 - 1:6 dilution can also be applied, but this significantly reduces the development rate and is therefore not a reasonable option for thicker resist films. If the requirements for steep resist sidewalls are low, the AZ® 351B can also be set stronger (1:3.5 - 1:3) if higher development rates are required , but this leads to a disproportionate increase in dark erosion. AZ® 351B is less suitable for negative resists or chemically amplified positive resists; TMAH-based developers such as the AZ® 326 MIF, AZ® 726 MIF or AZ® 2026 MIF are recommended here. AZ® 351B attacks aluminum with an etching rate of - depending on the concentration of the developer dilution - several 10 nm/min to over 100 nm/min. If this cannot be tolerated, the Al-compatible AZ® Developer can be an alternative.

AZ® 400K Developer 1:4
Inorganic, Metal Ion Containing Developer
General Information
AZ® 400K Developer 1:4 is a boric acid buffered, KOH-based ready-to-use developer for non-chemically amplified positive resists.
Product Features
AZ® 400K Developer 1:4 is an AZ® 400K that has already been pre-diluted for use. As a KOH-based developer, this developer is particularly suitable for developing thicker, non-chemically amplified positive resists, but can also be used for thinner resist layers if the resolution requirements are not too high. AZ® 400K Developer is less suitable for negative resists or chemically amplified positive resists; TMAH-based developers such as the AZ® 326 MIF, AZ® 726 MIF or AZ® 2026 MIF are recommended here. AZ® 400K Developer attacks aluminum with an etching rate of - depending on the concentration of the developer dilution - several 10 nm/min to over 100 nm/min.

AZ® 726 MIF Developer
Metal Ion-free Developers
General Information
AZ® 726 MIF is a TMAH-based developer for dip or puddle development, compatible with all AZ® photoresists from our portfolio.
Product Features
The ready-to-use AZ® 726 MIF Developer is an aqueous 2.38% TMAH solution with a surfactant for even substrate wetting for puddle development, but is also suitable for immersion development. For spray development, the surfactant-free AZ® 326 MIF would be the better choice to avoid foaming. TMAH-based developers are always used when metal ion-free development is required. In addition, TMAH-based developers are primarily recommended for our chemically amplified positive resists and our negative resists. For standard (non chemically amplified), DNQ-based positive resists without the requirement for metal ion-free development, a KOH or NaOH-based developer such as AZ® 400K or AZ® 351B can be considered instead of a TMAH-based developer for cost reasons. For cross-linking negative resists, the AZ® 2026 MIF can prove to be advantageous, as it promotes residue-free development with these resists thanks to certain additives.

AZ® 726 MIF attacks aluminum with an etching rate of approx. 70 nm/min.

AZ Developer - 5.00 l
1000001
AZ® Developer
Inorganic, Metal Ion Containing Developer
General Information
AZ® Developer is a sodium salt-based, aluminum-compatible developer for non-chemically amplified positive resists.
Product Features
AZ® Developer is based on an aqueous Sodium metasilicate/Sodium phosphate solution. In contrast to NaOH, KOH or TMAH-based developers, this developer does not show any significant aluminum attack and is suitable for the development of non-chemically amplified positive resists. For thicker resist layers or when the requirements for resolution and steepness of the resist sidewalls are not too high, the AZ® Developer can be used undiluted. For thin resists and higher resolution requirements, it can be diluted 1:1 with water. An AZ® Developer: Water = 2:1 dilution represents a good compromise for many applications. For negative resists or chemically amplified positive resists, the AZ® Developer usually does not show satisfactory results. TMAH-based developers are recommended for these, but these are not aluminum compatible.
