    摘要: A method for forming a semiconductor device is presented. The method includes providing a substrate having a photoresist thereon and transmitting a light source through a mask having a pattern onto the photoresist. The mask comprises a mask substrate having first, second and third regions, the third region is disposed between the first and second regions. The mask also includes a light reducing layer over the mask substrate having a first opening over the first region and a second opening over the second region. The first and second openings have layer sidewalls. The sidewalls of the light reducing layer are slanted at an angle less than 90 degrees from the plane of a top surface of the mask substrate. The method also includes developing the photoresist to transfer the pattern of the mask to the photoresist.

    摘要: A method for forming a phase shift mask is presented. The method includes providing a substrate including a transparent material having first, second and third regions, the third region being disposed between the first and second regions. The method also includes forming a light reducing layer on a first major surface of the substrate. The light reducing layer is patterned to form a patterned light reducing layer having sidewalls defining openings to expose the first and second regions. The patterned light reducing layer is processed to transform the sidewalls of the patterned light reducing layer to angled sidewalls having an angle of less than 90° from a plane of the first major surface of the substrate. The angled sidewalls improve intensity balance of an image-formed by light-transmitted through the mask.
