IT-1030

Negative Photo Resist Stripper

IT-1030 is a photo resist stripper exclusively developed for wafer level packaging process,  and a high functional solvent type bulk PR stripper to remove negative PR.

[Features]

• Exclusively developed for wafer bumping
• A bulk stripper which removes negative PR without ash/etch residue
• Removes PR without oxidation or damage to bump metal or bump metal substances
• Wide range of treatment condition (temp. & time)
• Evaporation loss is little due to high boiling point (180℃)
