    摘要: A semiconductor device includes at least one active component (18) having a p-n junction (26) on the semiconductor substrate in an active region (19) of the semiconductor substrate (4). A shallow trench isolation pattern is used to form a plurality of longitudinally extending shallow trenches (12) containing insulator (14). These trenches define a plurality of longitudinal active stripes (10) between the shallow trenches (12). The shallow trench isolation depth (dsπ) is greater than the junction depth (dsO of the longitudinal active stripes and the width (wsO of the active stripes (10) is less than the depletion length (ldepi) of the p-n junction.

    摘要: A FinFET and methods for its manufacture are provided. The method of the invention provides an elegant process for manufacturing FinFETs with separated gates. It is compatible with a wide range of dielectric materials and gate electrode materials, providing that the gate electrode material(s) can be deposited conformally. Provision of at least one upstanding structure (or “dummy fin”) (40) on each side of the fin (4) serves to locally increase the thickness of the gate electrode material layer (70). In particular, as the shortest distance between each upstanding structure (40) and the respective side of the fin (4) is arranged in accordance with the invention to be less than twice the thickness of the conformal layer, the thickness of the gate electrode material layer (70) all the way across this distance between each upstanding structure (40) and the fin (4) is increased relative to that over planar regions of the substrate (2). Thus, following an anisotropic etch to remove gate electrode material (70) overlying the fin (4), some material nevertheless remains between the upstanding structures and the fin. Thus, an enlarged area of gate electrode material is formed for use as a gate contact pad.
