Chrome Etch 18 is designed for use in microlithographic applications where high reproducibility and tight dimensional control are required.
The ready-to-use solution, which is based on acidic cerium-(IV) salt, is compatible with standard positive and negative tone resist systems.
The principle application is in thin-film technology like micro optics, optical gratings and thin film circuitry. It is also commonly used in mask manufacturing for etching bright or anti-reflective chromium thin-films on mask-blanks. Besides etching chromium, it can also be used to etch chrome-nickel alloys, silver, copper, molybdenum and tungsten films.
Chrome Etch 18 is a safe and easy to handle etchant, requiring standard safety precautions.
Custom solutions are available upon request.
