A doped silicon layer is formed on a silicon substrate. A silicon-germanium layer is subsequently formed on the doped silicon layer. The silicon-germanium layer is pattered to form a silicon-germanium feature. A silicon shell is formed on the silicon-germanium feature. At least a portion of the dopes silicon layer is converted to a porous silicon layer. Following the last step, the silicon shell is tensily stressed, making it a good candidate for use as a channel feature in an n-type field effect transistor."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Field effect transistors with strained channel features","description":"A method is provided for forming an integrated circuit.
