Answers to frequently asked questions from our MEMS Team
Does Brewer Science offer a photosensitive product for acid etch protection?
Brewer Science® ProTEK® PSA coating works for many acids.
What is the film thickness that can be achieved with Brewer Science® protective coatings and planarization materials?
Typically these materials are used to produce films that are 3 to 15 µm thick. Materials capable of producing films with other thicknesses may be available depending on the product.
Can our process use a higher bake temperature than that recommended by Brewer Science and still get good results?
Most, but not all, of Brewer Science's materials allow for higher bake temperatures than recommended.
Can our process use a lower bake temperature than that recommended by Brewer Science and still get good results?
In most cases, this is not possible. Brewer Science tries to design processes at the possible temperatures while maintaining robustness of the product.
Is applying a primer or adhesion promoter before the protective coating really necessary?
If a primer is specified for a product, then in most cases it is required. If no primer is specified, then a primer is not normally required.
How do you remove this product?
Most of Brewer Science's products can be removed using oxygen ashing or an organic stripper such as Piranha etchant. Some materials can be removed using a specific solvent.
