Esteves holds 2 patents that showcase his innovative approach to solving complex engineering challenges.
Latest Patents
One of Esteves' latest patents is titled "CMOS compatible low-resistivity Al—Sc metal etch stop." This invention presents an aluminum-scandium (Al—Sc) etch stop that is both highly conductive and compatible with CMOS technology. The low volatility of Sc in Cl and the strong covalent bond between Al and Sc enhance resistance to NaCl corrosion, making it an excellent etch stop material. This material is particularly effective when used with an overlying aluminum nitride (AlN) or aluminum scandium nitride (AlScN) piezoelectric layer. The Al—Sc composition, when deposited at high temperatures or annealed above 600° C, exhibits low resistivity, enabling device operation at temperatures up to at least 500° C.
Another significant patent by Esteves is "Metal stack templates for suppressing secondary grains in ScAlN." This invention discloses a metal stack for templating the growth of AlN and ScAlN films. The metal stack consists of one to three layers of metal, each compatible with CMOS post-processing. This innovative template promotes the growth of highly textured c-axis {002} AlN and ScAlN films, resulting in improved piezoelectric properties.
