    摘要: There is provided an exposure method that includes the steps of forming a phase shift mask having a desired pattern and a cyclic dummy pattern overlaid onto the desired pattern, a part of the desired pattern to be resolved by effects of the dummy pattern being thicker than the dummy pattern's line width, illuminating the phase shift mask by using illumination light having a peak near or on an optical axis in an intensity distribution to transfer the desired pattern onto the exposure plane by projecting light having passed through the phase shift mask onto the exposure plane.

    摘要: In a method of manufacturing non-volatile semi-conductor memory including a memory cell transistor and a peripheral transistor, a floating gate and a control gate of the memory cell transistor is formed on a semiconductor substrate and a gate electrode of the peripheral transistor is formed on the semiconductor substrate. The control gate and gate electrode are covered with first and second insulating layers, respectively. A conductive layer is deposited to cover the first and second insulating layers. The conductive layer is etched back until the first and second insulating layers are exposed. An erasing gate of the memory cell transistor is formed by leaving the conductive layer on the insulating layer. A first mask layer on the second insulating layer and a second mask layer on the erasing gate is formed. The conductive layer remaining in the regions outside the masks is removed.
