    摘要: An integrated circuit having multiple different device gate configurations and a method for fabricating the circuit are disclosed. An exemplary embodiment of forming the circuit includes receiving a substrate having a first device region, a second device region, and a third device region. A first interfacial layer is formed over at least a portion of each of the first device region, the second device region, and the third device region. The first interfacial layer is patterned to define a gate stack within the third device region. A second interfacial layer is formed over at least a portion of the second device region. The second interfacial layer is patterned to define a gate stack within the second device region. A third interfacial layer is formed over at least a portion of the first device region. The third interfacial layer defines a gate stack within the first device region.

    摘要: The present disclosure provides a method of fabricating a semiconductor device. The method includes forming a first gate structure and a second gate structure over a substrate. The first and second gate structures each include a high-k dielectric layer located over the substrate, a capping layer located over the high-k dielectric layer, an N-type work function metal layer located over the capping layer, and a polysilicon layer located over the N-type work function metal layer. The method includes forming an inter-layer dielectric (ILD) layer over the substrate, the first gate structure, and the second gate structure. The method includes polishing the ILD layer until a surface of the ILD layer is substantially co-planar with surfaces of the first gate structure and the second gate structure. The method includes replacing portions of the second gate structure with a metal gate. A silicidation process is then performed to the semiconductor device.

    摘要: A method for fabricating a semiconductor device includes receiving a silicon substrate having an isolation feature disposed on the substrate and a well adjacent the isolation feature, wherein the well includes a first dopant. The method also includes etching a recess to remove a portion of the well and epitaxially growing a silicon layer (EPI layer) in the recess to form a channel, wherein the channel includes a second dopant. The method also includes forming a barrier layer between the well and the EPI layer, the barrier layer including at least one of either silicon carbon or silicon oxide. The barrier layer can be formed either before or after the channel. The method further includes forming a gate electrode disposed over the channel and forming a source and drain in the well.
