Latest Patents

Hong-seong Son holds a patent for a pre-treatment method performed on a semiconductor structure before forming hemi-spherical grains of a capacitor storage node. This innovative method aims to improve the growth of hemi-spherical grains (HSGs) on a semiconductor structure by effectively removing etching residue prior to the formation of the capacitor storage node. The process involves dry-etching a material layer on the surface of a semiconductor substrate to create a storage node pattern. Following this, multiple ashing sequences are executed using an etching gas, and a stripping step with H₂SO₄ is performed to eliminate any remaining residue. The semiconductor structure is then cleaned with an ammonium peroxide mixture (APM), allowing for the successful growth of HSGs on the capacitor storage nodes.
