In an embodiment a first step comprises forming a bulk region of the source/drain region using a first precursor, a second precursor, and an etching precursor. A second step comprises cleaning the bulk region with the etchant along with introducing a shaping dopant to the bulk region in order to modify the crystalline structure of the exposed surfaces. A third step comprises forming a finishing region of the source/drain region using the first precursor, the second precursor, and the etching precursor."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor device having a shaped epitaxial region","description":"A source/drain region of a semiconductor device is formed using an epitaxial growth process.
