    摘要: A method of forming transistors with close proximity stressors to channel regions of the transistors is provided. The method includes forming a first transistor, in a first region of a substrate, having a gate stack on top of the first region of the substrate and a set of spacers adjacent to sidewalls of the gate stack, the first region including a source and drain region of the first transistor; forming a second transistor, in a second region of the substrate, having a gate stack on top of the second region of the substrate and a set of spacers adjacent to sidewalls of the gate stack, the second region including a source and drain region of the second transistor; covering the first transistor with a photo-resist mask without covering the second transistor; creating recesses in the source and drain regions of the second transistor; and forming stressors in the recesses.
