Imprint Materials / AL33




ÅngströmLink AL-33xx series polymers are optically clear with excellent stability and processing capabilities. These products feature a siloxane (silicon-oxygen) backbone with epoxy functional groups. This combination provides for extremely stable mechanical, electrical and optical properties at, or after exposure to high temperature.

The AL-33xx polymers are 100% solids. At room temperature, these polymers have long pot life. The uncured polymers are soluble in a variety of solvents for spin coating and produce a very uniform coating thickness across large areas (12 inch wafers).

Curing can be accomplished with both UV and heat. These materials can be photo-imaged and etched for pattern delineation processes. The cured polymers have excellent chemical and solvent resistance.

These products are supplied in light-sensitive protected bottles. These polymers offer a service temperature range of -40°C to + 350°C (+400°C for short periods of time).
