METHOD OF MANUFACTURING GATE STRUCTURE AND METHOD OF MANUFACTURING FIN-FIELD EFFECT TRANSISTOR - A simplified explanation of the abstract

This abstract first appeared for US patent application 18522265 titled 'METHOD OF MANUFACTURING GATE STRUCTURE AND METHOD OF MANUFACTURING FIN-FIELD EFFECT TRANSISTOR

Simplified Explanation

The abstract describes a method of manufacturing a gate structure involving the formation of various layers including a gate dielectric layer, work function layer, barrier layer, and metal layer with fluorine atoms. The barrier layer is formed by depositing a first TiN layer, converting a top portion into a trapping layer with silicon or aluminum atoms, and then forming a second TiN layer on top.

  • Formation of gate dielectric layer
