    摘要： Methods of forming non-volatile memory devices include the steps of forming a semiconductor substrate having first and second floating gate electrodes thereon and an electrically insulating region extending between the first and second floating gate electrodes. A step is then performed to etch back the electrically insulating region to expose upper corners of the first and second floating gate electrodes. Another etching step is then performed. This etching step includes exposing upper surfaces and the exposed upper corners of the first and second floating gate electrodes to an etchant that rounds the exposed upper corners of the first and second floating gate electrodes. The step of etching back the electrically insulating region includes etching back the electrically insulating region to expose sidewalls of the first and second floating gate electrodes having heights ranging from about 30 Å to about 200 Å. The step of exposing the upper corners of the first and second floating gate electrodes to an etchant is followed by the step of etching back the electrically insulating region to expose entire sidewalls of the first and second floating gate electrodes.

    摘要： A method of manufacturing a semiconductor device includes forming an insulation pattern over a substrate. The insulation pattern has at least one opening that exposes a surface of the substrate. Then, a first polysilicon layer is formed over the substrates such that the first polysilicon layer fills the opening. The first polysilicon layer also includes a void therein. An upper portion of the first polysilicon layer is removed such that void expands to a recess and the recess is exposed. A second polysilicon layer is formed over the substrate such that the second polysilicon layer fills the recess.

    摘要： A copolymer having a repeating unit represented by the following general formula I and a chemical amplification positive photoresist composition having the copolymer and a photoacid generator. The photoresist can allow for a good pattern shape even though a post-baking is taken in a somewhat delayed time and for a use of any radiation, such as uv light, deep uv light and charged particle beam. Also, it is superior in storage stability and resolution so that it is useful for the high integration of semiconductor devices. The polymer ranges, in polystyrene-reduced average molecular weight, from 1,000 to 1,000,000. The polymer is represented by the following repeating pattern: ##STR1## wherein, R.sub.1, R.sub.2 and R.sub.3 independently represent a hydrogen atom or a methyl; R.sub.4, R.sub.5 and R.sub.6 independently represent a hydrogen atom, an alkyl group, an alkoxy group or a halogen; 1, m, n each is a repeating number satisfying the condition that 0.3
