    • A phase-shifting mask suited for equal line/space, small pitched, dense line pattern is disclosed. The phase-shifting mask includes a transparent substrate, a partially shielded mesa line pattern of first phase formed on the substrate, and a clear recessed line pattern of second phase etched into the substrate and is disposed right next to the partially shielded mesa line pattern. The partially shielded mesa line pattern has a plurality of alternating 5%-10% transmittance light-shielding regions and clear regions of the first phase. The partially shielded mesa line pattern and the clear recessed line pattern have the same line width. The light that passes through the clear regions of the first phase and the light that passes through the clear recessed line pattern of second phase have a phase difference of 180 degree.
    • 公开了适合于相等的线/空间,小直径,密集线图案的相移掩模。 所述移相掩模包括透明基板,在所述基板上形成的第一相的部分屏蔽的台面线图形,以及蚀刻到所述基板中的第二相的清晰凹陷线图案,并且紧邻所述部分屏蔽的台面线图案设置。 部分屏蔽的台面线图案具有多个交替的5%-10%的透光遮光区域和第一相的透明区域。 部分屏蔽的台面线图案和清晰的凹陷线图案具有相同的线宽。 通过第一相的透明区域的光和通过第二相的清晰凹陷线图案的光具有180度的相位差。

    • A phase-shifting mask suited for equal line/space, small pitched, dense line pattern is disclosed. The phase-shifting mask includes a transparent substrate, a partially shielded mesa line pattern of first phase formed on the substrate, and a 100% clear recessed line pattern of second phase etched into the substrate and is disposed right next to the partially shielded mesa line pattern. The partially shielded mesa line pattern has a plurality of alternating 45-degree, oblique areas and 100% transmittance clear regions of the first phase. The partially shielded mesa line pattern and the clear recessed line pattern have the same line width. The light that passes through the clear regions of the first phase and the light that passes through the clear recessed line pattern of second phase have a phase difference of 180 degree.
