Photoresist Removers

Organic materials specifically formulated to remove positive & negative photoresist from substrate surfaces.

Posistrip® Removers

EKC800™
EKC800™ is designed to remove positive photoresist that has experienced standard processing with normal thermal history.

EKC830™
EKC830™ is designed to effectively remove positive photoresist resulting from harsh prior processing that is difficult to remove.

EKC865™
EKC865™ is specifically formulated to prevent attack of sensitive metals. It will remove positive photoresist with normal thermal history.

Universal Removers

EKC922™
EKC922™ is used to remove photoresist over cured or semi-cured polyimide without attack.

EKC944™
EKC944™ is designed for use at elevated temperatures for hard-to-remove photoresist layers. Used with a solvent rinse, this product will remove harshly treated photoresist providing extremely clean surfaces as demonstrated by low CV shift.

Negative Removers

EKC1020™
EKC1020™ is designed to be compatible with sensitive metals where corrosion is a concern.
