Product Properties<\/th>\n<\/tr>\n<\/thead>\n
Description<\/td>\n\n Etchant for chromium thin films for microelectronics applications offering excellent compatibility with both positive and negative photoresists.
\n Provides fine-line control with minimal undercutting. High purity formulations filtered to 0.2 micron are ideal for critical devices.
\n 1020AC has a slower etch rate compared to 1020, which eliminates undercutting and enhances broader compatibility.\n <\/td>\n<\/tr>\n
How to Increase Etch Rate<\/td>\n\n 1. The rate will approximately double with every 10\u00b0C increase in temperature.
\n 2. Increase the rate of stirring or agitation.\n <\/td>\n<\/tr>\n
How to Reduce Etch Rate<\/td>\nAdd 1 part deionized water to 2 parts etchant (reduces etch rate by ~50%).<\/td>\n<\/tr>\n
Do I Need to Dilute It?<\/td>\nNo, it is ready to use.<\/td>\n<\/tr>\n
