    摘要: A faceted intrinsic buffer semiconductor material is deposited on sidewalls of a source trench and a drain trench by selective epitaxy. A facet adjoins each edge at which an outer sidewall of a gate spacer adjoins a sidewall of the source trench or the drain trench. A doped semiconductor material is subsequently deposited to fill the source trench and the drain trench. The doped semiconductor material can be deposited such that the facets of the intrinsic buffer semiconductor material are extended and inner sidewalls of the deposited doped semiconductor material merges in each of the source trench and the drain trench. The doped semiconductor material can subsequently grow upward. Faceted intrinsic buffer semiconductor material portions allow greater outdiffusion of dopants near faceted corners while suppressing diffusion of dopants in regions of uniform width, thereby suppressing short channel effects.

    摘要: A composition and method for forming a field effect transistor with a stable n-doped nano-component. The method includes forming a gate dielectric on a gate, forming a channel comprising a nano-component on the gate dielectric, forming a source over a first region of the nano-component, forming a drain over a second region of the nano-component to form a field effect transistor, and exposing a portion of a nano-component of a field effect transistor to dihydrotetraazapentacene, wherein dihydrotetraazapentacene is represented by the formula: wherein each of R1, R2, R3, and R4 comprises one of hydrogen, an alkyl group of C1 to C16 carbons, an alkoxy group, an alkylthio group, a trialkylsilane group, a hydroxymethyl group, a carboxylic acid group and a carboxylic ester group.
