    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 with 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 embodiment method for forming a layout for a phase shift mask. A embodiment comprises providing a layout comprising a first feature, a first shifter region and a second shifter region. The first feature preferably has a L-shape portion with an elbow region. The first shifter region is on the outside of the L-shaped portion and the second shifter region is on the inside of the L-shaped portion. The elbow region has an outside corner away from the second shifter region. We identify a phase conflict region caused by the L-shaped portion of the first feature, the first shifter region and the second shifter region. We resolve the phase conflict by modifying the elbow region by moving the outside corner of the elbow region away from the first shifter region and the phase conflict region. The modification of the elbow region further comprises forming a jog region in the line end section of the first feature.

    摘要: A structure, a method of fabricating and a method of using a phase shift mask (PSM) having a first phase shifted section, a half tone section, and a second phase shifted section. The first phase shift section and the half tone section are shifted 180 degrees with the second phase shift region. Embodiments provide for (1) a half tone, single trench alternating phase shift mask and (2) a half tone, dual trench alternating phase shift mask. The half tone region provides advantages over conventional alternating phase shift masks.

    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.
