Product Properties<\/th>\n<\/tr>\n<\/thead>\n
Description<\/td>\n\n Etchant for chromium thin films for microelectronics applications offering excellent compatibility with positive and negative photoresists.
\n It provides fine-line control with minimal undercutting. High purity formulations filtered to 0.2 micron are ideal for critical devices.
\n Transene Chromium Etchants 1020AC is a high purity ceric ammonium nitrate system for precise, clean etching of chromium and chromium oxide films.
\n It is nitric acid-free and exhibits a slower etch rate. 1020AC shows minimal undercutting.\n <\/td>\n<\/tr>\n
Features<\/td>\n\n High purity, 0.2 micron filtration, Excellent photoresist compatibility, Uniform etch rates and patterns\n <\/td>\n<\/tr>\n
How to Increase Etch Rate?<\/td>\n1. The rate will approximately double with every 10\u00b0C increase in temperature.
2. Increase the rate of stirring or agitation.<\/td>\n<\/tr>\n
How to Reduce Etch Rate?<\/td>\nAdding 1 part deionized water to 2 parts etchant will reduce the etch rate approximately 50%.<\/td>\n<\/tr>\n
Do I Need to Dilute the Etchant?<\/td>\nNo, it is ready to use.<\/td>\n<\/tr>\n
How to Reduce Undercutting?<\/td>\nIncrease the rate of stirring or agitation.<\/td>\n<\/tr>\n
