Latest Patents

Kusuki holds a patent for a method that enhances the etching of TiSi. The patent, titled "Method for enhancing etching of TiSix," presents a solution to the residue problem often encountered with traditional etching techniques. Conventional methods typically use chlorine or hydrogen bromide as plasma etchants, which can leave undesirable residues due to silicon nodules in the TiSi. Kusuki's invention introduces a fluorine-containing gas to the plasma etchant, effectively etching the silicon nodules at a rate comparable to that of TiSi, thereby preventing residue formation. This innovative method involves exposing the surface of TiSi to a plasma etchant that includes at least one fluorine-containing gas, such as sulfur hexafluoride (SF6), nitrogen trifluoride (NF3), or carbon tetrafluoride (CF4), along with a gas selected from hydrogen bromide or chlorine.
