Latest Patents

Maruyama's latest patents include an innovative anti-reflective coating forming composition. This composition contains a reaction product of an isocyanuric acid compound with a benzoic acid compound. The resulting anti-reflective coating exhibits a high preventive effect against reflected light and does not intermingle with photoresists. This technology allows for the formation of photoresist patterns without footing at the lower part, making it suitable for lithography processes using light sources such as ArF excimer laser beams and F2 excimer laser beams.

Another significant patent is the pattern reversal film forming composition and method of forming a reversed pattern. This composition is designed to create a pattern reversal film that does not mix with the resist pattern on a substrate. It can form a planar film that is temporally stable, regardless of the resist pattern's granularity. The composition includes a polysiloxane, an additive, and an organic solvent, showcasing Maruyama's expertise in chemical engineering.
