摘要:
At least one method, apparatus and system disclosed herein involves forming trench silicide region contact. A plurality of fins are formed on a semiconductor substrate. An epitaxial (EPI) feature is formed at a top portion of each fin of the first portion over a first portion of the fins. A gate region is formed over a second portion of the fins. A replacement metal gate (RMG) process is performed in the gate region. A trench is formed in a portion of the gate region. A void is formed adjacent the a portion of the gate region. A first silicon feature is formed in the trench. A second silicon feature is formed in the void. A TS cut region is formed over the trench. The first silicon feature and the second silicon feature are removed. A metallization process is performed in the void to form a contact.
