WebJan 1, 2013 · The C poly contribution, which is frequently referred to as poly-silicon depletion, is a result of the sum of inversion and depletion charges in the substrate being greater than the impurity density (N poly) near the poly-Si—oxide interface.Since charge neutrality requires that the field lines for every carrier in the substrate are screened by the … Webdimensions, Poly-Silicon gate depletion is a growing concern for the semiconductor industry. However, it is possible to further decrease the Poly-Silicon gate's dopant … WebIt will be obseved that even for a poly gate doped to 1e20/cm3, depletion occurs in the poly gate giving anomolous C-V characteristics. This can have serious consequences if the … qg smoke club
