Latest Patents

One of his latest patents is titled "Titanium nitride gapfill processes for semiconductor structures." This patent describes methods for forming structures that are beneficial for front-end-of-line (FEOL) and back-end-of-line (BEOL) processes. The methods involve depositing titanium nitride (TiN) as a gapfill material in high aspect ratio structures with small dimensions. The embodiments provide seam-free, high-quality TiN films that effectively fill high aspect ratio trenches. Additionally, the patent includes selective deposition processes using a carbon layer to achieve seam-free TiN gapfill in three-dimensional structures, such as gate-all-around (GAA) devices.

Another notable patent focuses on "Methods of improving PMOS transistor performance." This patent outlines methods for manufacturing electronic devices, particularly transistors, by inhibiting the growth of the N-metal layer. The disclosure presents two types of processes that significantly reduce or inhibit N-metal layer growth on the titanium nitride surface of PMOS transistors. These processes involve forming a self-assembled monolayer on the metal surface and creating a silicon-containing layer on the TiN surface.
