Abstract
A sidewall spacer pullback scheme is implemented in forming a transistor. The scheme, among other things, allows silicide regions of the transistor to be made larger, or rather have a larger surface area. The larger surface area has a lower resistance and thus allows voltages to be applied to the transistor more accurately. The scheme also allows transistors to be made slightly thinner so that the formation of voids in a layer of dielectric material formed over the transistors is mitigated. This mitigates yield loss by facilitating more predictable or otherwise desirable transistor behavior.
