摘要:
Complementary metal oxide semiconductor metal gate transistors may be formed by depositing a metal layer in trenches formerly inhabited by patterned gate structures. The patterned gate structures may have been formed of polysilicon in one embodiment. The trenches may be filled with metal by surface activating using a catalytic metal, followed by electroless deposition of a seed layer followed by superconformal filling bottom up.
