Latest Patents
One of Asenov's latest patents is titled "Reduced local threshold voltage variation MOSFET using multiple layers of epi for improved device operation." This invention discloses a device structure that utilizes multiple layers of low-temperature epitaxy, eliminating the need for source and drain implants. The design provides a planar interface with abrupt junctions between epitaxial extensions and the substrate, which mitigates electrostatic coupling between the transistor drain and channel, thereby reducing short channel effects. The reduction of channel doping leads to improved device performance by minimizing impurity scattering and random dopant-induced threshold voltage variations (sigma-Vt). By avoiding implants, the device further reduces sigma-Vt due to the diffusion of random dopants from source and drain extensions, which can create variations in channel length during thermal activation anneal. The defined transistor structure employs at least two levels of low-temperature epitaxy, resulting in performance improvements across various types of transistor substrates. Additionally, mixed epitaxial layer growth materials that induce tensile or compressive gate stresses can be used to further enhance device characteristics.
