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 … WebAnalytical and numerical gate capacitance models with polysilicon (poly) depletion effect are studied by directly solving the coupled Poisson equations on the poly and silicon …

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. WebMeasurement of the gate oxide 1) HRTEM (High resolution transmission electron microscope) - ... 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]. Physical and analytical models for PD effect ... ava eisenson
