    • A method to mend a black defect and a white defect of a phase shift mask pattern so that the mended phase shift mask pattern has an accurately defined pattern. In the vicinity of a black defect and the area around the same, a mending phase shifter is formed into a thickness twice as large as the thickness d of a phase shifter. All light beams through a black defect area are nearly 0 degree out of phase with a non-phase-shifted light beam, thereby the phase shift mask pattern having the black defect becoming a phase shift mask pattern with an accurately defined pattern. In a similar manner, every light beam through a white defect area is nearly 180 degree out of phase with a non-phase-shifted light beam. As a result, a mended phase shift mask pattern has an accurately defined pattern.
    • 一种修复相移掩模图案的黑色缺陷和白色缺陷的方法,使得修饰的相移掩模图案具有精确限定的图案。 在黑色缺陷附近及其周围的区域,修整移相器形成为移相器的厚度d的两倍的厚度。 通过黑色缺陷区域的所有光束与非相移光束几乎相差0度,从而具有黑色缺陷的相移掩模图案变为具有精确限定图案的相移掩模图案。 以类似的方式,通过白色缺陷区域的每个光束与非相移光束几乎相差180度。 结果,修正的相移掩模图案具有精确定义的图案。

    • A method of manufacturing a semiconductor capacitor provided with a substrate, a dielectric film formed on the substrate and a pair of electrode layers stacked on both sides of the dielectric film comprises a step of forming a polycrystalline silicon layer for serving as one of the electrode layers on the substrate, a step of making at least a surface region of the polycrystalline silicon layer amorphous, a step of forming the dielectric film on the polycrystalline silicon layer while maintaining an amorphous surface state, and a step of forming another one of the electrode layers on the dielectric film. The lower electrode of the capacitor has its surface or the whole layer made amorphous. The surface of the electrode which is amorphous has smooth surface configuration, thereby improving the quality of the dielectric film formed thereon.
