Latest Patents

Chang-Iyoung Song holds a patent titled "Methods for manufacturing semiconductor devices having chamfered metal silicide layers." This patent describes a method for creating a semiconductor device where a chamfered metal silicide layer is formed using a two-stage continuous wet etching process with different etchants. This innovative approach results in a sufficient insulation margin between a lower conductive layer, which includes the metal silicide layer, and the contact plug that is self-aligned with the lower conductive layer. The process involves forming a mask pattern on the metal silicide layer, exposing a portion of it, and then isotropically etching the exposed area to create a metal silicide layer with a shallow groove. The subsequent use of a second etchant removes defects, resulting in a smooth surface for the metal silicide layer. The methods also disclose microelectronic structures produced through this innovative process.
