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.

Developer

AZ^® 400K Developer, AZ^® 826 MIF Developer recommended;
AZ^® 351B possible.
