    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 liquid immersion scanning exposure system utilizes an immersion liquid confined within a watertight lens hood having a base portion formed from a solid optical element. During operation, a bottom portion of a lens assembly is disposed within the immersion liquid and the solid optical element is placed upon a photoresist material or layer (to be patterned). The lens assembly moves laterally through the immersion liquid parallel to the photoresist material. Because the solid optical element separates the immersion liquid from the photoresist material and does not move relative to the photoresist material, the photoresist material does not contact with the immersion liquid and the solid optical element and is not susceptible to damage or scratching by the solid optical element.

    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.
