    摘要: Semiconductor devices with low junction capacitances and methods of fabrication thereof are described. In one embodiment, a method of forming a semiconductor device includes forming isolation regions in a substrate to form active areas. The sidewalls of the active areas are enclosed by the isolation regions. The isolation regions are recessed to expose first parts of the sidewalls of the active areas. The first parts of the sidewalls of the active areas are covered with spacers. The isolation regions are etched to expose second parts of the sidewalls of the active area, the second parts being disposed below the first parts. The active areas are etched through the exposed second parts of the sidewalls to form lateral openings. The lateral openings are filled with a spin on dielectric.

    摘要: A semiconductor structure includes a semiconductor substrate having a first portion and a second portion. A first Fin field-effect transistor (FinFET) is formed over the first portion of the semiconductor substrate, wherein the first FinFET includes a first fin having a first fin height. A second FinFET is formed over the second portion of the semiconductor substrate, wherein the second FinFET includes a second fin having a second fin height different from the first fin height. A top surface of the first fin is substantially level with a top surface of the second fin. A punch-through stopper is underlying and adjoining the first FinFET, wherein the punch-through stopper isolates the first fin from the first portion of the semiconductor substrate.

    摘要: System and method for reducing contact resistance and prevent variations due to misalignment of contacts is disclosed. A preferred embodiment comprises a non-planar transistor with source/drain regions located within a fin. An inter-layer dielectric overlies the non-planar transistor, and contacts are formed to the source/drain region through the inter-layer dielectric. The contacts preferably come into contact with multiple surfaces of the fin so as to increase the contact area between the contacts and the fin.
