Thermal Acid Generators
With thicker film resist demands, more and more formulations contain thermal acid generators to enable final curing during post-baking.
An IP-free set of products with different acidreleasing temperatures is available from Heraeus. Semiconductor-grade purity and effective costs are mandatory in the final application.
