    Abstract: Unitary structures having conductive portions electrically separated by non-conductive portions are described. In some embodiments, the non-conductive portions are made of metal oxide. In some embodiments, the method involves an oxidizing process adapted to convert an entire thickness at a selected portion of a metal substrate to a metal oxide, thereby creating metal portions that are electrically isolated from one another. In some embodiments, the thickness of the metal substrate is reduced at certain regions prior to oxidizing in order to provide a sufficiently thin metal for complete oxidization through the entire thickness. In some embodiments, the oxidizing process involves a plasma electrolytic oxidation process. In some embodiments, the plasma is concentrated at certain regions of the substrate for preferential oxidation. Applications for the substrate include enclosures and electrical components for electronic devices that use radio frequency communication.

    Abstract translation: 描述具有由非导电部分电隔离的导电部分的单一结构。 在一些实施例中，非导电部分由金属氧化物制成。 在一些实施例中，该方法涉及一种氧化工艺，其适用于将金属衬底的选定部分处的整个厚度转换为金属氧化物，从而产生彼此电隔离的金属部分。 在一些实施例中，金属基板的厚度在氧化之前在某些区域被减小，以便提供足够薄的金属以在整个厚度上完全氧化。 在一些实施方案中，氧化工艺涉及等离子体电解氧化工艺。 在一些实施例中，等离子体被浓缩在衬底的某些区域以进行优先氧化。 用于基板的应用包括使用射频通信的电子设备的外壳和电气部件。
