WebA method of forming a semiconductor device. A substrate having a fin structure is provided. A dummy gate is formed on the fin structure. A polymer block is formed adjacent to a corner between the dummy gate and the fin structure. The polymer block is subjected to a nitrogen plasma treatment, thereby forming a nitridation layer in proximity to a sidewall of the … Web(a) Series resistances and their components of 100 nm-gate-length NMOSFET as a function of gate voltage estimated by advanced model.

Dashed lines WebUnscalable poly depletion necessitates a metal gate instead of the conventional poly gate [4, 5]. In order to achieve n and pMOSFETs on the highly doped substrate, two different metal gates are needed whose workfunction is close to the conduction (~4.1eV) and valence-band edges (~5.2eV) of the Si substrate for n and pMOSFETs, respectively. simply psychology controlled observations
