| Product Properties | |
|---|---|
| Description | Etchant for chromium thin films for microelectronics applications offering excellent compatibility with both positive and negative photoresists. Provides fine-line control with minimal undercutting. High purity formulations filtered to 0.2 micron are ideal for critical devices. 1020AC has a slower etch rate compared to 1020, which eliminates undercutting and enhances broader compatibility. |
| How to Increase Etch Rate | 1. The rate will approximately double with every 10°C increase in temperature. 2. Increase the rate of stirring or agitation. |
| How to Reduce Etch Rate | Add 1 part deionized water to 2 parts etchant (reduces etch rate by ~50%). |
| Do I Need to Dilute It? | No, it is ready to use. |
| How to Reduce Undercutting | Increase the rate of stirring or agitation. |
