Abstract:
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.
