    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.

    Abstract: A method of forming holes in a layer through a cross-shape image exposure. The method includes removing a section from each corner of the rectangular patterns on a photomask to form cross-shape patterns so that circular or elliptical contact holes are formed on a photoresist layer after photo-exposure and development. Optical image contrast between contacts is increased by the cross-shape patterns on the photomask.

    Abstract: A stringer block is formed on the interface between a HDP silicon oxide layer and a silicon substrate. During an etching process for defining the profile of a floating gate, the stringer block functions to expose a bottom corner stringer. Following that, a polysilicon etching process effectively removes the bottom corner stringer. As a result, a stringerless flash memory cell is formed to prevent leakage currents, resulting from the bottom corner stringer, and improve both the reliability and data retention ability of the device.

    Abstract: A method of code programming a mask read only memory (ROM) is disclosed. According to the method, a first photoresist layer is formed over word lines and a gate oxide layer of a substrate already having implanted bit lines. The first photoresist layer is patterned to develop pre-code openings over all of the memory cells, which correspond to intersecting word and bit lines. The first photoresist layer is then hardened using either a treatment implant or a treatment plasma. Subsequently, a second photoresist layer is formed over the first photoresist layer and patterned to develop real-code openings over memory cells which are actually to be coded with a logic “0” value. Each memory cell to be coded is then implanted with implants passing through the pre-code openings and the real code openings and into the memory cell.
