Description
例示的な実施形態において、銅酸化物層はグレインを有し、調整の後にはこれらグレインは250ナノメータ以下のサイズを有する。別の実施形態において、銅酸化物層はグレインを有し、調整の後にはこれらグレインは200ナノメータ以下のサイズを有する。いくつかの実施形態において、銅酸化物層はグレインを有し、調整の後にはこれらグレインは実質的に不規則に配向している。 In an exemplary embodiment, the copper oxide layer has a grain, these grains after adjustments have a size equal to or less than 250 nanometers. In another embodiment, the copper oxide layer has grains , and after conditioning these grains have a size of 200 nanometers or less. In some embodiments, the copper oxide layer has a grain, these grains after adjustments are substantially randomly oriented.
銅表面は、銅表面を酸化剤に暴露することによって安定化される。例示の実施形態において、酸化剤は亜塩素酸ナトリウム、過酸化水素、過マンガン酸塩、過塩素酸塩、過硫酸塩、オゾン、又はこれら物質の混合物のうちのいずれか1つ以上から選択される。銅表面を安定化させるステップは、室温〜約80℃の範囲の温度で行うことができる。 The copper surface is stabilized by exposing the copper surface to an oxidizing agent. In an exemplary embodiment, the oxidizing agent is selected from one or more of sodium chlorite, hydrogen peroxide, permanganate, perchlorate, persulfate, ozone, or a mixture of these substances. The The step of stabilizing the copper surface can be performed at a temperature ranging from room temperature to about 80 ° C.
例示の実施形態において、銅酸化物層は非常に分散したグレイン構造を有し、調整の後にはグレインは200ナノメータ以下のサイズを有する。別の実施形態において、銅酸化物層はグレインを有し、調整の後にはこれらグレインは100ナノメータ以下のサイズを有する。いくつかの実施形態において、銅酸化物はグレインを有し、調整の後にはこれらグレインは実質的にランダムに配向している。 In the illustrated embodiment, the copper oxide layer has a highly dispersed grain structure, and after conditioning the grains have a size of 200 nanometers or less. In another embodiment, the copper oxide layer has a grain, these grains after adjustments have a size equal to or less than 100 nanometers. In some embodiments, the copper oxide has a grain, these grains after adjustments are oriented in substantially random.
図3Aは、ノジュール状グレイン及び長距離秩序の結晶構造を反映する一方向性グレイン成長を有する、従来の電解銅表面(すなわち、滑らかな銅表面、若しくは言い換えると粗化されていない銅表面)の典型的なモルフォロジーを示す、50,000倍の例示的SEM写真である。比較として、本発明の方法に従って処理された電解銅表面のモルフォロジーが、図3Bに示されている。非常に明確であるように、図3Bに示された、処理された銅表面上の安定化層は、グレインがより細かく、グレイン成長が一方向性ではなく、均一性がより高いモルフォロジーを示している。対照的に、図3Cは既存の黒色酸化物表面を示し、この表面は非常に厚く、壊れやすい繊維状構造を示している。図3Dは、既存のマイクロエッチされた銅表面の例示的SEM写真であり、この表面は非常に不均一なマイクロな畝状モルフォロジーを示している。 FIG. 3A shows a conventional electrolytic copper surface (ie, a smooth copper surface or, in other words, an unroughened copper surface) with unidirectional grain growth reflecting a nodular grain and a long-range ordered crystal structure. 2 is an exemplary SEM photo at 50,000 times showing typical morphology. As a comparison, the morphology of the electrolytic copper surface treated according to the method of the present invention is shown in FIG. 3B. As is very clear, as shown in FIG. 3B, stabilizing layer on the treated copper surface, grain rather finer, grain growth rather than a unidirectional, higher morphological uniformity Show. In contrast, FIG. 3C shows an existing black oxide surface, which is very thick and shows a fragile fibrous structure. FIG. 3D is an exemplary SEM photo of an existing micro-etched copper surface, which shows a very non-uniform micro-cocoon morphology.
