Do you know a photoresist with high optical transparency and low water absorption ?

20 September 2020 0 6K Report

Hi,

I am looking for a photoresist that has high optical transparency between 1300-1650 nm range with very low water absorption. Another important specification is being able to thermally reflow it. If anyone knows such a resist, I would be very happy to hear. Refractive index above 1.5-1.55 would be sufficient.

many thanks in advance
