METHOD TO CONTROL METAL SEMICONDUCTOR MICRO-STRUCTURE |
摘要 |
A method of forming a metal semiconductor alloy that includes forming an intermixed metal semiconductor region to a first depth of a semiconductor substrate without thermal diffusion. The intermixed metal semiconductor region is annealed to form a textured metal semiconductor alloy. A second metal layer is formed on the textured metal semiconductor alloy. The second metal layer on the textured metal semiconductor alloy is then annealed to form a metal semiconductor alloy contact, in which metal elements from the second metal layer are diffused through the textured metal semiconductor alloy to provide a templated metal semiconductor alloy. The templated metal semiconductor alloy includes a grain size that is greater than 2× for the metal semiconductor alloy, which has a thickness ranging from 15 nm to 50 nm.
