    Abstract: The present disclosure provides a method for fabricating a semiconductor device that includes providing a silicon substrate, forming a gate stack over the silicon substrate, performing a biased dry etching process to the substrate to remove a portion of the silicon substrate, thereby forming a recess region in the silicon substrate, performing a non-biased etching process to the recess region in the silicon substrate, thereby forming a bottle-neck shaped recess region in the silicon substrate, and epi-growing a semiconductor material in the bottle-neck shaped recess region in the silicon substrate. An embodiment may include a biased dry etching process including adding HeO2 gas and HBr gas. An embodiment may include performing a first biased dry etching process including N2 gas and performing a second biased dry etching process not including N2 gas. An embodiment may include performing an oxidation process to the recess region in the silicon substrate by adding oxygen gas to form silicon oxide on a portion of the recess region in the silicon substrate. As such, these processes form polymer protection to help form the bottle-neck shaped recess.

A dielectric layer is formed over the exposed conductive layer. An anti-reflective coating layer is formed over the dielectric layer. The anti-reflective layer and the dielectric layer are etched using a via opening process to form an initial via exposing a portion of the conductive layer. A protective film portion is formed over at least the exposed portion of the conductive layer. The anti-reflective coating layer and the dielectric layer are patterned to reduce the initial via to a reduced via and to form a trench opening substantially centered over the reduced via. The trench opening and the reduced via comprising the dual damascene opening.

    Abstract: A shallow trench isolation (STI) structure has a top portion tapering in width from wide to narrow in a direction from a substrate surface, from a first width at a top of the first portion to a second width at a bottom of the first portion. The STI structure also includes a bottom portion below the top portion, which expands from the bottom of the top portion to a substantially widened lateral distance having a third width. The third width is, in general, substantially larger than the second width. The inventive STI structure can provide desired isolation characteristics with a significantly reduced aspect ratio, thus suitable for device isolations in advanced processing technology.
