The depletion effects of gate poly-Si are investigated in detail taking into consideration the fact that many-body effects due to carrier-carrier and … 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 …

WebIt is usually assumed that the poly gate in a MOSFET is doped at a concentration such that depletion in the gate either does not occur or that any depletion effects can safely be ignored. This article aims to quantify poly depletion effects for typical sub-micron device dimensions using ATHENA and ATLAS process and device simulators. WebPoly-Si/sub 0.8/Ge/sub 0.2/-and poly-Si-gated PMOS capacitors with very thin gate oxides were fabricated. Boron penetration and poly-gate depletion effects (PDE) in these devices were both analyzed.
WebNear the edge of the gates (L ge ), the poly-Si gate depletion is noticeable due to the presence of strong fringing fields at the gate edge along the Z-direction [32].
WebNov 1, 1995 · INTRODUCTION The dual polysilicon gate process may become widely accepted for ULSI fabrication [l]. One potential problem with the p 'poly gate is its likelihood of lower doping.
