SOLVENTS
In addition to etching processes, the
solubilities of substances often play a decisive role in microstructuring. This does not
only apply to the structuring of organic layers, but to all
wet chemical etching processes: In addition to chemical removal, the
etched substances must be dissolved in the etching medium.

Purity:
ULSI
Acetone
CH3COCH3
General Information
Acetone removes organic impurities from substrates and is well suited for greasy/oily contaminations. However, its large vapour pressure causes rapid drying together with a resorption of the contaminants on the substrate. Therefore an immediately subse¬quent rinsing step is recommended with a higher boiling solvent such as isopropanol.
Acetone is not well-suited as lift-off medium due to the high fire danger when heated and the trend of particles to be lifted to resorb onto the substrate.

AZ EBR 70/30 - 1.00 l
10703021
Bottle size:
1.00 l
AZ® EBR Solvent 70/30
1-methoxy-2-propyl-acetate
General Information
AZ® EBR Solvent 70/30 is the main solvent/thinner of almost all AZ® and TI photoresists due to its low vapour pressure and its suppression of particle formation in the (further diluted) resist. Additionally, PGMEA is often used for edge bead removal, since its low vapour pressure prevents further thinning of the coated resist film.

DMSO - 2.50 l - ULSI
MDMU1025
DMSO
Dimethyl Sulfoxide
General Information
Due to its low vapour pressure and its water solubility, DMSO is an excellent stripper for resists respectively Lift-off media and is a non-toxic substitute for the NMP, which has been classified as toxic since a while. The optional addition of Cyclopentanone or MEK increases the performance of the stripper for certain applications and significantly lowers the melting point of pure DMSO.
NOTE:
The solvent DMSO (dimethyl sulfoxide) has a melting point just below room temperature, so it can possi¬bly freeze in storage in cooler rooms. Thawing may require several days, but afterwards the product can still be used as it is.

MC Spray Thinner MEK - 1.00 l
1SPTHM001
Bottle size:
1.00 l
MC Spray Thinner MEK
Solvent for Spray Coating
General Information
Spray Thinner MEK is a solvent for the production of a spray coating formulation. As the name suggests, this thinner is based on a formulation of MEK and various surfactants, which help to achieve an optimal spray coating result.
Spray coating formulations are often made from three components - the low-boiling Spray Thinner MEK, the high-boiling Spray Thinner PGMEA and the corresponding resist. Depending on the mixing ratio and the wanted result, the proportions of the substances must be adjusted.
A high proportion of PGMEA (low vapor pressure) creates very smooth layers with moderate edge coverage, while a formulation with a high MEK content (high vapor pressure) creates very good edge coverage but comparatively rough layers.
The optimal compromise of the solvent mixture is often a mixing ratio MEK: PGMEA of 1:3 to 3:1. Depending on the viscosity, required by the spray coating tool used, this solvent mixture is added to the resist in a ratio of 1:3 to 1:10. So one part resist to 3 parts solvent mixture up to one part resist to 10 parts solvent mixture.
