Latest Patents

One of his latest patents is titled "Dielectric-metal stack for 3D flash memory application." This patent describes a method for forming a stack of film layers for use in 3D memory devices. The process begins with providing a substrate in a processing chamber of a deposition reactor. Subsequently, process gases suitable for forming a dielectric layer are introduced, creating a dielectric layer on the substrate. Following this, additional process gases are used to form a metallic layer on the dielectric layer, and then a metallic nitride adhesion layer is added. This sequence is repeated to achieve the desired number of layers.

Another significant patent is "Conformal amorphous carbon for spacer and spacer protection applications." This method involves forming a nitrogen-doped amorphous carbon layer on a substrate. The process includes depositing a sacrificial dielectric layer, creating patterned features by removing portions of this layer, and then depositing a nitrogen-doped amorphous carbon layer. The nitrogen-doped layer is selectively removed to provide filled patterned features within sidewall spacers formed from the carbon layer.
