Surface Analysis of TMCTS-Based SiOC(H) Low-<i>k</i> Dielectrics in Post-Etch Strip of ACL Hardmask
The miniaturization of devices requires the introduction of a high aspect ratio through patterning in the Damascene copper interconnect process. The high aspect ratio etch process employs hardmasks, such as amorphous carbon, that can withstand high-powered plasma exposure. When an etch hardmask is r...
