    Abstract: Embodiments of the disclosure generally provide a method of forming a reduced dimension pattern in a hardmask that is optically matched to an overlying photoresist layer. The method generally comprises of application of a dimension shrinking conformal carbon layer over the field region, sidewalls, and bottom portion of the patterned photoresist and the underlying hardmask at temperatures below the decomposition temperature of the photoresist. The methods and embodiments herein further involve removal of the conformal carbon layer from the bottom portion of the patterned photoresist and the hardmask by an etch process to expose the hardmask, etching the exposed hardmask substrate at the bottom portion, followed by the simultaneous removal of the conformal carbon layer, the photoresist, and other carbonaceous components. A hardmask with reduced dimension features for further pattern transfer is thus yielded.

    Abstract: Embodiments of the present invention provide a methods for patterning a hardmask layer with good process control for an ion implantation process, particularly suitable for manufacturing the fin field effect transistor (FinFET) for semiconductor chips. In one embodiment, a method of patterning a hardmask layer disposed on a substrate includes forming a planarization layer over a hardmask layer disposed on a substrate, disposing a patterned photoresist layer over the planarization layer, patterning the planarization layer and the hardmask layer uncovered by the patterned photoresist layer in a processing chamber, exposing a first portion of the underlying substrate, and removing the planarization layer from the substrate.
