    Abstract: A self aligned contact pad in a semiconductor device and a method for forming the self aligned contact pad are disclosed. A bit line contact pad and a storage node contact pad are simultaneously formed by using a photoresist layer pattern having a T-shaped opening including at least two contact regions. An etch stopping layer is formed over a semiconductor substrate and over a transistor. An interlayer dielectric layer is then formed over the etch stopping layer. Next, the interlayer dielectric layer is planarized to have a planar top surface. A mask pattern having a T-shaped opening is then formed over the interlayer dielectric layer, exposing the active region and a portion of the inactive region. The interlayer dielectric layer and etch stopping layer are sequentially etched to reveal a top surface of the semiconductor substrate using the mask pattern, thereby forming a self aligned contact opening exposing a top surface of the semiconductor substrate. The mask pattern is then removed. A conductive layer is formed in the self aligned contact opening and over the interlayer dielectric layer. The conductive layer and the interlayer dielectric layer are planarization-etched to reveal a top surface of the gate mask, thereby forming at least two contact pads.

    Abstract: Non-volatile memory devices include a tunnel insulating layer on a channel region of a substrate, a charge-trapping layer pattern on the tunnel insulating layer and a first blocking layer pattern on the charge-trapping layer pattern. Second blocking layer patterns are on the tunnel insulating layer proximate sidewalls of the charge-trapping layer pattern. The second blocking layer patterns are configured to limit lateral diffusion of electrons trapped in the charge-trapping layer pattern. A gate electrode is on the first blocking layer pattern. The second blocking layer patterns may prevent lateral diffusion of the electrons trapped in the charge-trapping layer pattern.
