摘要:
A non-volatile memory device and a method of fabricating the same are provided. The method can include disposing an isolation layer on a semiconductor substrate. The isolation layer may protrude from the main surface of the semiconductor substrate and define an active region. In a recess defined by the protrusion of the isolation layer and the active region, a diffusion-retarding poly pattern and a floating gate may be formed in sequence. A control gate may be disposed on the isolation layer to cover the diffusion-retarding poly pattern and the floating gate.
摘要:
An etch stop layer is formed over a first structure by depositing a metal oxide material over the first structure and annealing the deposited metal oxide material. A second structure is formed over the etch stop layer, and a formation is etched through the second structure using the etch stop layer as an etch stop.
摘要:
In an embodiment, a storage electrode of a capacitor in a semiconductor device is resistant to inadvertent etching during its manufacturing processes. A method of forming the storage electrode of the capacitor is described. The storage electrode of the capacitor may include a first metal layer electrically connected with a source region of a transistor through a contact plug penetrating an insulating layer on a semiconductor substrate. A polysilicon layer may then be formed on the first metal layer. A second metal layer is formed on the polysilicon layer.
