Photoresist Solvents. A negative photoresist when exposed to light polymerizes doe

A negative photoresist when exposed to light polymerizes does not dissolve in the developer. Further Information Our safety data sheets and some of our technical data sheets are password-protected. Polyimide is not attacked by NRR-001. Photoresist-covered slides are soft baked at 115 °C for 1 min to harden the photoresist layer by removing excess solvent. The last solvent tank which the panels see prior to water rinsing, is the only tank which is made up of fresh solvent. Thinning / Edge Wall Removal If the resist is to be diluted for spin coating, PGMEA = AZ® EBR Solvent is the recommended solvent. Solvents like TMAH and NMP dissolve resist layers faster at higher temperatures because chemical processes accelerate. The thin film was exposed by a laser and developed with a solvent to give two types of resist patterns: positive tone and negative tone. This solvent bench is equipped with a static, heated bath (PRS-3000) and a heated, recirculated, filtered bath (NMP). Etching: Using the patterned photoresist as a mask, the exposed areas of the silicon wafer are etched away by chemical or plasma etchants. hp74nstg
