| azonenberg | First attempt at "wet DRIE" | 08:39 |
| azonenberg | more precisely high aspect ratio wet etching using a process loosely based on Bosch | 08:39 |
| azonenberg | notice the wavy sidewalls | 08:39 |
| azonenberg | this was three steps of coat PR/expose/develop and HCl:H2O2 isotropic wet etch | 08:39 |
| azonenberg | requires precise mask alignment but theoretically allows higher aspect ratios | 08:39 |
| azonenberg | Who here was asking about where to buy CNTs? http://www.tedpella.com/gold_html/Nanotubes.htm | 19:47 |
