AZ® 4999
Spray Coating
General Information
AZ®4999 is a spray coating dedicated highly transparent photoresist tailored to excel on special spray coating equipment (e.g. SUSS Delta AltaSpray) where it provides defect free and conformal coatings on devices with severe topography. Thick (several to several tens of microns) and uniform resist coatings are obtained on topography such as V-grooves and trenches with optimum coverage of sharp edges. There is no accumulation of resist in trenches. The use of AZ®4999 photoresist enables high reproducibility in volume production applications.
Product Properties
- Viscosity (at 25°C): 0.52 cSt
- Solids content: 4 %
- Absorptivity at 398 nm: 0.1 l/(g*cm) Spectral sensitivity: 310 nm – 440 nm
Developers
If metal ion containing developers can be used, the KOH-based AZ® 400K in a 1:4 dilution (for higher resist film thicknesses 1:3.5 - 1:3 diluted possible) is a suited developer.
If metal ion free developers have to be used, we recommend the TMAH-based AZ® 2026 MIF developer (undiluted).
Removers
For non cross-linked resist films the AZ® 100 Remover, DMSO or other common organic solvents cab be used as stripper. If the resist film is crosslinked (e. g. by high temperature steps > 140°C, during plasma processes such as dry etching, or during ion implantation), we recommend the NMP-free TechniStrip P1316 as remover. AZ® 920 Remover can be a good choice as well, in case of harsh treated, hard to remove resist residuals.
Thinning/ Edge Bead Removal
We recommend for thinning and edge bead removal the products AZ® EBR Solvent or PGMEA.
