AZ Anti-collapse Rinses

EMD Performance Materials' anti-collapse rinse products provide wider process window capabilities for advanced 193nm photoresists.
By applying the anti-collapse rinse after the photoresist development and DI water rinse steps, the pattern collapse behavior is significantly improved.
Thus the photoresist film thickness can be increased to a level suitable for the substrate etch process while maintaining a manufacturable process window.
