Latest Patents

Among his latest patented inventions is a groundbreaking method of generating multiple oxides by plasma nitridation on oxide. This method involves the formation of multiple gate oxide thicknesses on active areas that are separated by STI isolation regions on a substrate. The process begins with the growth of a first layer of oxide, approximately 50 Angstroms thick, from which selected regions are subsequently removed. A second, thinner layer of oxide is then grown, which allows for the creation of three different gate oxide thicknesses. Selected regions are nitridated with nitrogen plasma, which enhances the dielectric constant of the gate oxide while reducing the effective oxide thickness. This innovative nitridation technique not only prevents impurity dopants from migrating across the gate oxide layer but also decreases standby current leakage and minimizes corner loss of STI regions caused by HF etchant.
