Abstract: A novel method for eliminating or reducing the accumulation of electrostatic charges on semiconductor wafers during spin-rinse-drying of the wafers is disclosed. The method includes rinsing a wafer; applying an ionic solution to the wafer; and spin-drying the wafer. During the spin-drying step, the ionic solution neutralizes electrostatic charges on the wafer as the wafer is rotated. This reduces the formation of defects in devices fabricated on the wafer, as well as prevents or reduces electrostatic interference with processing equipment during photolithographic and other fabrication processes.

Abstract: A method of fabricating a phase shift mask (PSM) is described. A patterned photoresist layer is formed on an opaque layer over a transparent plate. A thin mask layer is formed on the sidewalls of the patterned photoresist layer. The exposed opaque layer and transparent plate thereunder are then removed while using the patterned photoresist layer and mask layer as a mask. A phase shift opening is formed in the transparent plate, and thereby a phase shift layer is formed at the place where the phase shift opening is located. The patterned photoresist layer and the opaque layer thereunder are then removed to expose the transparent plate. The opaque layer under the mask layer can precisely self-align the phase shift layer to prevent alignment deviation caused by multiple lithography processes. The precision of the phase shift mask can be increased, and mask manufacture cost can be lowered.

Abstract: A method of forming a feature pattern in a photosensitive layer includes forming the photosensitive layer on a substrate, providing a first mask having a first opaque area thereon, and performing a first exposure process with a first dose to form a first unexposed image in the photosensitive layer. The method further includes performing a second exposure process with a second dose to expose sidewalls of the first unexposed image so that the sidewalls of the first unexposed image receive at least a portion of the second dose thus forming a second unexposed image in the photosensitive layer, and developing the photosensitive layer with a developing process to form the feature pattern and to create features having smaller widths than those which would result in developing the photosensitive layer of the first unexposed image.
