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. WebDec 3, 2003 · Inadequate dopant activation in the poly-Si gate results in carrier depletion at the gate/gate oxide interface (poly-depletion), which in turn degrades the device's drive … refugee camp in thailand hmong
Polysilicon Gate Depletion Effects in Sub-Micron MOSFETs
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 … WebSep 19, 2005 · 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 carrier-ion … 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. This may cause polysilicon gate depletion (PD) effect that results in MOS C-V and I-V characteristics degradation [2].
