Latest Patents

One of Ho-Ouk Lee's latest patents is a method of fabricating a semiconductor device by exposing the upper sidewalls of a contact plug to form a charge storage electrode. According to the patent, the method involves forming at least two contact plugs that penetrate an insulating layer to connect with a semiconductor substrate. The contact plugs have an upper surface and upper sidewalls that are higher than the top surface of the insulating layer. An etch stop covers the contact plugs and the insulating layer, while a molding layer is formed over the etch stop layer. The molding layer is then etched to create a molding pattern with an opening. The bottom of the opening includes a central region that exposes the etch stop on the upper surface and a peripheral region that extends from the central region and the etch stop layer. The etch stop is etched to expose the upper surface, allowing for the formation of storage electrodes that contact the contact plugs. The molding pattern is subsequently removed to reveal the storage electrodes. Other embodiments of this method are also described and claimed.
