Abstract: A method for verifying optical proximity correction (OPC) using a layer-versus-layer (LVL) comparison. The method includes performing optical proximity correction of an original design of a semiconductor device to prepare a revised design of the semiconductor device; comparing the revised design and the original design with each other; dividing deviation patterns, obtained by results of the comparison, according to an illuminating system; and comparing the divided deviation patterns respectively to reference values to determine whether or not any error in the optical proximity correction occurs.

Abstract: A nonvolatile memory device has a floating gate with its top and side surfaces covered by ONO film to improve the data retention of the floating gate. The ONO film has upper and lower silicon dioxide layers interposed by silicon nitride layer thinner than the oxide layers. A method includes the steps of forming a tunnel oxide layer on a silicon substrate, depositing a first polysilicon film on the tunnel oxide layer, patterning the first polysilicon film to form a floating gate, depositing oxide-nitride-oxide (ONO) film on the substrate surface to cover top and side surfaces of the floating gate, depositing a second polysilicon film on the ONO film, patterning the second polysilicon film to form a control gate, and selectively etching the ONO film to form an interlayer dielectric layer interposing between the floating and control gates and a sidewall spacer dielectric layer on sidewalls of the floating gate.
