    • The invention includes methods in which silicon is removed from titanium-containing container structures with an etching composition having a phosphorus-and-oxygen-containing compound therein. The etching composition can, for example, include one or both of ammonium hydroxide and tetra-methyl ammonium hydroxide. The invention also includes methods in which titanium-containing whiskers are removed from between titanium-containing capacitor electrodes. Such removal can be, for example, accomplished with an etch utilizing one or more of hydrofluoric acid, ammonium fluoride, nitric acid and hydrogen peroxide.
    • 本发明包括使用其中含有含磷和氧的化合物的蚀刻组合物从含钛容器结构中除去硅的方法。 蚀刻组合物可以例如包括氢氧化铵和四甲基氢氧化铵中的一种或两种。 本发明还包括从含钛电容器电极之间除去含钛晶须的方法。 这种去除可以例如通过使用氢氟酸,氟化铵,硝酸和过氧化氢中的一种或多种的蚀刻来实现。

    • The invention includes an etchant composition containing isopropyl alcohol and one or more of HF, NH4F and tetramethyl ammonium fluoride (TMAF). The invention encompasses a method of processing a substrate. A substrate is provided which has a first material containing at least one of polysilicon, monocrystalline silicon and amorphous silicon, and a second material. The substrate is exposed to an etch composition which comprises isopropyl alcohol and at least one of HF, NH4F and TMAF. The invention includes a method of processing a semiconductor construction including providing a construction which has a capacitor electrode material and an oxide material along at least a portion of the capacitor electrode material. At least some of the oxide material is removed by isotropic etching utilizing an etchant composition comprising isopropyl alcohol.
