    摘要: An integrated circuit structure includes a substrate and a fin field-effect transistor (FinFET). The FinFET includes a fin over the substrate and having a first fin portion and a second fin portion. A gate stack is formed on a top surface and sidewalls of the first fin portion. An epitaxial semiconductor layer has a first portion formed directly over the second fin portion, and a second portion formed on sidewalls of the second fin portion. A silicide layer is formed on the epitaxial semiconductor layer. A peripheral ratio of a total length of an effective silicide peripheral of the FinFET to a total length of a fin peripheral of the FinFET is greater than 1.

    摘要: A method for fabricating a semiconductor device is disclosed. An exemplary embodiment of the method includes providing a substrate; forming a fin structure over the substrate; forming a gate structure, wherein the gate structure overlies a portion of the fin structure; forming a sacrificial-offset-protection layer over another portion of the fin structure; and thereafter performing an implantation process.

    摘要: Method of manufacturing a semiconductor chip. An array region gate stack is formed on an array region of a substrate and a periphery region gate stack is formed on a periphery region of a substrate. A first dielectric material, a charge-storing material, and a second dielectric material are deposited over the substrate. Portions of the first dielectric material, the charge-storing material, and the second dielectric material are removed to form storage structures on the array region gate stack and on the periphery region gate stack. The storage structures have a generally L-shaped cross-section. A first source/drain region is formed in the array region well. A third dielectric material and a spacer material are deposited over the substrate. Portions of the third dielectric material and the spacer material are removed to form spacers. A second source/drain region is formed in the periphery region well.
