EUV sensitizer for resists and spin-on-carbon materials

We are developing the EUV sensitizer for resists and Spin-on-Carbon materials. In previous report, we reported that we had developed the novel materials containing the iodine having high EUV absorption ability, and EUV absorption rate proved to be calculable from density and element composition. In this report, we calculated the improvement rate of the EUV absorption rate when materials with high EUV absorption were used for EUV sensitizers. As the result of this, we found that materials with high EUV absorption were useful for EUV sensitizers. Additionally, we will also report on new materials with a high EUV absorption ability.
