Product Description:
The Allresist AR-BR 5480 is a high-performance bottom anti-reflective coating (BARC) designed for advanced semiconductor, MEMS, and micro-/nanofabrication lithography processes. It is engineered to minimise substrate reflectivity and interference effects, improving critical dimension (CD) control, pattern fidelity, and overall lithography process stability.
AR-BR 5480 effectively suppresses standing waves, reflective notching, and linewidth variation caused by substrate reflections, enabling the formation of precise, high-resolution photoresist patterns. Its optical properties are tuned for compatibility with common exposure wavelengths, making it ideal for both R&D and production environments.
Characterisation:
- bottom resist not light sensitivity
- broadband UV, i-line, g-line for top resist
- for lift-off structures
- for optically transparent structures from 270 nm to IR with thermally stable structures up to 250 °C
- aqueous-alkaline development
- temperature-stable up to 140 °C (with AR-P 3500)
- 5400 copolymer methyl methacrylate/methacrylic acid
- 3- safer solvent PM (5400), PGMEA (3500, 4340)
