Photodefineable and Non-Photodefineable Liquid Chemistries

We offer a broad line of photodefinable or standard (non-photodefinable) products and ancillaries.

After our customers apply and cure our liquid chemistries, they become Polyimide and PBO films that are high temperature engineering polymers which exhibit an exceptional combination of thermal stability (>500°C), mechanical toughness and chemical resistance. In addition, they have excellent dielectric properties. Because of their high degree of ductility and inherently low CTE, these cured films can be readily implemented into a variety of microelectronic applications.

Photodefineable
Photodefineable materials can be patterned directly by exposure to UV light. They can either harden with exposure (negative acting) or soften with exposure (positive acting). The softer areas are then removed with either.

Non-photodefinable
Non-photodefinable materials are patterned by applying a photoresist or other type of mask and removing the polyimide either by:
