Reduced Local Threshold Voltage Variation MOSFET Using Multiple Layers of Epi for Improved Device Operation
A device structure with multiple layers of low temperature epitaxy is disclosed that eliminates source and drain and extension implants, providing a planar interface with abrupt junctions between epitaxial extensions and substrate, mitigating electrostatic coupling between transistor drain and transistor channel and reducing short channel effects. The reduction of channel doping results in improved device performance from reduced impurity scattering and reduction of random dopant induced threshold voltage variations (sigma-Vt). Avoiding implants further reduces device sigma-Vt due to random dopants' diffusion from source and drain extensions, which creates device channel length variations during thermal activation anneal of implanted dopants. The defined transistor structure employs at least two levels of low-temperature epitaxy, and creates a planar interface with various types of transistor substrates resulting in performance improvement. Mixed epitaxial layer growth materials inducing tensile or compressive gate stresses can be advantageously used with the invention to further improve device characteristics.
