Abstract
An integrated circuit and a method of making a transistor thereof are provided. The method includes the steps of forming a first stack on the substrate and a second stack on substrate in spaced-apart relation to the first stack, where the first stack has a first layer and first and second spacers adjacent to the first layer and the second stack has a second layer and third and fourth spacers adjacent to the second layer. A gate dielectric layer is formed on the substrate between the first and second stacks and a first conductor layer is formed on the gate dielectric layer. A first source/drain region is formed beneath the first conductor layer and a second source/drain region is formed beneath the second conductor layer. The first and second layers are removed and a first contact is formed on the first source/drain region and a second contact is formed on the second source/drain region. The method integrates gate and source/drain region formation and provides for gate electrodes with work functions tailored for n-channel and p-channel devices.
