Abstract:
Etching a feature of a structure by an etch system is facilitated by varying supply of radio frequency (RF) power pulses to the etch system. The varying provides at least one RF power pulse, of the supplied RF power pulses, that deviates from one or more other RF power pulses, of the supplied RF power pulses, by at least one characteristic.
Abstract:
Embodiments of the present invention provide an improved structure and method of contact formation. A cap nitride is removed from a gate in a region that is distanced from a fin. This facilitates reduced process steps, allowing the gate and the source/drain regions to be opened in the same process step. Extreme Ultraviolet Lithography (EUVL) may be used to pattern the resist to form the contacts.
Abstract:
Semiconductor structures and fabrication methods are provided which includes, for instance, providing a gate structure over a semiconductor substrate, the gate structure including multiple conformal gate layers and a gate material disposed within the multiple conformal gate layers; recessing a portion of the multiple conformal gate layers below an upper surface of the gate structure, where upper surfaces of recessed, multiple conformal gate layers are coplanar; and removing a portion of the gate material to facilitate an upper surface of a remaining portion of the gate material to be coplanar with an upper surface of the recessed, multiple conformal gate layers.
