    Abstract: A method of forming a photolithographic mask for use in fabricating a semiconductor device is provided. The method includes forming a layer of photoresist material on a wafer and exposing the photoresist material to a light source. The photoresist material is developed, and before the wafer dries, the wafer is cleaned with one or more cleaning liquids. The cleaning liquid may be a surfactant, an acid, a dissolved gas solution (e.g., CO2, SO2, SO3, NH3, NO2, or the like), deionized water, or the like. Thereafter, the wafer is dried. The wafer may be dried, for example, by a spin dry process, a gas purge process using, for example, compressed dry air, N2, CO2, Ar, or the like, or a drying alcohol such as IPA vapor.

    Abstract: A method of fabricating a non-volatile memory is provided. A longitudinal strip of stacked layer is formed over a substrate. The longitudinal strip is a stacked layer including a gate dielectric layer, a conductive layer and a cap layer. A buried bit line is formed in the substrate on each side of the longitudinal strip. The longitudinal strip is patterned to form a plurality of stacked blocks. Thereafter, a dielectric layer is formed over the substrate. The dielectric layer exposes the cap layer of the stacked blocks. Some cap layers of the stacked blocks are removed to expose the conductive layer underneath. A word line is formed over the dielectric layer to connect stacked blocks in the same row serially together.

    Abstract: A method of enhancing photoresist anti-etching ability, at least includes follows. Provide a substrate, form a photoresist with a pattern on the substrate, put both photoresist and substrate in a low pressure environment, and treat photoresist by an electron beam to let at least part of photoresist is hardened. This method usually is performed before etch process, but the method also could be modified as follows. Expose photoresist by an electron beam while an etching process being performed, or alternately expose photoresist by an electron beam and perform an etch process.

    Abstract: The present invention discloses a method of forming a slope lateral structure. In this invention, the silicon nitride and the silicon hydroxide with different etching rates are used. Thus, when the silicon nitride is etching, the top and laterals portion of the silicon hydroxide is suffering the slight etching. So that, when the silicon nitride is etched completely, a slope lateral silicon hydroxide is formed, because of the different etching time on the top and the bottom portion of the silicon hydroxide. Using the present invention, the conventional NROM process problem, which the wordlines are connected by the residue on the laterals of the protective layer after etching process can be solved.

    Abstract: A method of removing small particles remaining on a surface of a semiconductor wafer and preventing a silicide layer covering the semiconductor wafer from corroding starts by controlling a temperature of the semiconductor wafer to between room temperature and 45° C. Then, a cleaning solution of a temperature between 0° C. and 45° C. is utilized to clean the semiconductor wafer to effectively remove small particles remaining on the surface of the semiconductor wafer and prevent the silicide layer from corrosion by the cleaning solution. Therein, the cleaning solution is comprised of a pre-determined volume ratio of hydrogen peroxide (H2O2), ammonia (NH4OH), and deionized water.
