Wafer-level micro-structuring of glassy carbon
Aluminum and titanium were used as hard mask for reactive ion etching of glassy carbon (Figure 2: B and C). The fabrication steps are similar for both processes. Two thin titanium layers are sputtered before and after aluminium deposition to increase the adhesion between the aluminium hard mask and both substrate and photoresist. The metallic
