Abstract

The invention includes a method of forming a gated semiconductor assembly. A first transistor gate layer is formed over a substrate. A silicon nitride layer is formed over the first transistor gate layer. The silicon nitride layer comprises a first portion and a second portion elevationally displaced above the first portion. The first portion has less electrical resistance than the second portion and a different stoichiometric composition than the second portion. The first portion is physically against the second portion. A second transistor gate layer is formed over the silicon nitride layer.
