Advanced Transistor Process Technology from 22- to 14-nm Node
Transistor performance meets great technical challenges as the critical dimension (CD) shrinking beyond 32/28-nm nodes. A series of innovated process technologies such as high-k/metal gate, strain engineering, and 3D FinFET to overcome these challenges are reviewed in this chapter. The principle, developing route, and main prosperities of these technologies are systematically described with theoretical analysis and experimental results. Especially, the material choice, film stack design, and process flow integration approach with high-k/metal gate for sub-22-nm node is introduced; the film growth technique, process optimization, and flow integration method with advanced strain engineering are investigated; the architecture design, critical process definition, and integration scheme matching with traditional planar 2D transistor for 14-nm 3D FinFET are summarized.
