    摘要: The present invention relates to a method of forming a small gap using CMP and a method for manufacturing a lateral FED. In the present invention, a small gap is determined by the thickness of an oxide film, and so uniform small gaps of about 100 Å that have been impossible to attain with the art of prior lithography can be formed with repeatability. Prior lateral field emission devices have the problem of repeatability in forming a gap for field emission because they are fabricated by means of a thermal stress method or an electrical stress method. But if the method of forming a small gap according to the present invention is used to fabricate a lateral FED, a FED can be made that has low voltage drive and high current drive characteristics and uniform field emission characteristics.

    摘要: A semiconductor memory device is fabricated by forming an active region protruding from a semiconductor substrate, forming an isolation layer on the substrate adjacent opposing sidewalls of the active region, and forming a floating gate electrode on a surface of the active region between the opposing sidewalls thereof. The floating gate electrode is formed to extend beyond edges of the surface of the active region onto the isolation layer. A surface of the floating gate electrode adjacent the active region defines a plane, and the isolation layer is confined between the plane and the substrate. A control gate electrode is formed on a surface of the floating gate electrode opposite the active region. The control gate electrode may be formed to extend along sidewalls of the floating gate electrode towards the substrate beyond the plane defined by the surface of the floating gate electrode adjacent the active region. Related devices are also discussed.
