Patent ID: 7301190

Claim:
A memory cell comprising: a capacitor; and at least one transistor having a gate, drain, and source, wherein the drain is interconnected to the capacitor through a semiconductor structure, wherein the semiconductor structure comprises: an insulator layer having a first substance, wherein the first substance is selected from a group consisting of a polymer, a foamed polymer, a fluorinated polymer, a fluorinated-foamed polymer, an aerogel, and an insulator oxide compound, wherein the polymer includes polyimide, and wherein the insulator oxide compound includes silicon dioxide; an inhibiting layer on the insulator layer, wherein the inhibiting layer comprises a compound formed from a reaction that includes the first substance and a second substance, wherein the second substance is selected from a group consisting of a transition metal, a representative metal, and a metalloid, and wherein the transition metal is selected from a group consisting of chromium, molybdenum, tungsten, titanium, zirconium, hafnium, vanadium, niobium, and tantalum, wherein the representative metal is selected from a group consisting of aluminum and magnesium, and wherein the metalloid includes boron; and a copper metallization layer on the inhibiting layer.
