摘要： A corrosion-inhibiting cleaning composition for semiconductor wafer processing includes hydrogen peroxide at a concentration in a range from about 0.5 wt % to about 5 wt %, sulfuric acid at a concentration in a range from about 1 wt % to about 10 wt %, hydrogen fluoride at a concentration in a range from about 0.01 wt % to about 1 wt %; an azole at a concentration in a range from about 0.1 wt % to about 5 wt % and deionized water. The azole operates to inhibit corrosion of a metal layer being cleaned by chelating with a surface of the metal layer during a cleaning process.

摘要： In a cleaning solution and a method of cleaning a semiconductor substrate, the cleaning solution includes about 1 to about 10 percent by weight of sulfuric acid, about 0.5 to about 5 percent by weight of aqueous hydrogen peroxide solution, and about 85 to about 98.5 percent by weight of hydrogen fluoric acid solution. Various polymers attached to a metal wiring formed on a substrate are removed by immersing the substrate into the cleaning solution. The substrate is rinsed to remove the cleaning solution remaining on the substrate. Thus, the polymers can be completely removed without damage to the metal wiring and an underlying oxide film.

摘要： Methods of forming an electronic structure can include forming an interlayer insulating layer on a substrate, and forming a storage node comprising a base and sidewalls extending away from the base. The interlayer insulating layer can have a contact hole therein exposing a portion of the substrate. Moreover, the storage node base can be in the contact hole and the sidewalls can extend away from the base and away from the substrate with portions of the sidewalls being within the contact hole and with portions of the sidewalls extending outside the contact hole beyond the interlayer insulating layer away from the substrate. Related structures are also discussed.
