Latest Patents

Ahn holds a patent for a device isolation method of a semiconductor device. This method involves the formation of a pad oxide layer and a nitride layer on a semiconductor substrate. The nitride layer above the device isolation region is then removed, creating an undercut by partially etching the pad oxide layer. Following this, a first oxide layer is formed on the exposed substrate, and a polysilicon spacer is added to the sidewalls of the nitride layer. A void is intentionally created in the oxide layer under the nitride layer, which enhances cell definition and stabilizes device isolation. This innovative technique effectively resolves issues associated with conventional LOCOS methods.
