WebThe litho exposure was performed using a 193nm immersion scanner with NA=1.35. After 1st pass litho (L1), the 1st pass etch (E1) broke through the BARC and OPL layer, etched into the ILD layer, and lastly removed the remaining PR/BARC/OPL trilayer. The etch process also shrank the bottom CD from 40nm post-litho to 18 nm post-etch. Web5 mei 2024 · Above you will see the final drawing before etching. 3. The first etch follows much the same method as stone lithography. The difference is, if you are going to add acid you use Phosphoric acid – not Nitric which is used with stone litho. In my case I used straight Gum Arabic. Apply Rosin – be very gentle; Apply Talc – be equally gentle
