摘要： The surface of a metal base is electroplated by utilizing an induction codeposition phenomenon using at least one of carbon dioxide and inert gas, an electroplating liquid containing a metal powder dispersed therein, and a surfactant in a supercritical state or a subcritical state. The concentration of the metal in the electroplating liquid is in a saturated or supersaturated state. Accordingly, the dissolution speed of the metal base can be suppressed, and, at the same time, a plating layer having a smooth surface can be formed in a short time by utilizing an induction codeposition phenomenon. The electroplating method can be applied even when the metal base is formed of a metallic thin film provided on a surface of an insulating film provided on the substrate, or even when the metal is copper, zinc, iron, nickel, or cobalt. The above constitution can provide an electroplating method which, in electroplating on the surface of a metal base, can prevent the dissolution of the metal base to realize normal electroplating even in the case of a very thin metal base.
摘要翻译：使用二氧化碳和惰性气体中的至少一种，含有分散在其中的金属粉末的电镀液体和超临界状态或亚临界状态的表面活性剂，利用感应共沉淀现象对金属基体的表面进行电镀。电镀液中金属的浓度处于饱和或过饱和状态。因此，可以抑制金属基体的溶解速度，并且同时可以通过利用感应共沉积现象在短时间内形成具有光滑表面的镀层。即使当金属基底由设置在基板上的绝缘膜的表面上设置的金属薄膜形成时，或甚至当金属为铜，锌，铁，镍或钴时，也可以应用电镀方法。上述结构可以提供一种电镀方法，即使在非常薄的金属基底的情况下，在金属基材表面的电镀中也能够防止金属基体的溶解，从而实现正常的电镀。

摘要： This invention provides an electroless plating method comprising electrolessly plating the surface of a metal base sample (22) using a supercritical fluid or a subcritical fluid in such a state that a metal powder is dispersed in an electroless plating liquid (19). According to this method, a homogeneous and thick plating layer is formed in a short time by taking advantage of an induction eutectoid phenomenon. In the electroless plating method, the metal powder may have an average particle diameter of not less than 1 nm and not more than 100 mum, and the electroless plating method may also be applied to a damascene process or a dual damascene process which is a method for forming a fine metal wiring within a semiconductor element. The above constitution can provide an electroless plating method which can realize the formation of an even film by electroless plating in a short time using a subcritical fluid or a supercritical fluid by taking advantage of an induction eutectoid phenomenon. ® KIPO & WIPO 2009
摘要翻译：本发明提供了一种化学镀方法，其包括使金属粉末分散在无电镀液体（19）中的状态下，使用超临界流体或亚临界流体对金属基体样品（22）的表面进行电镀。根据该方法，通过利用感应共析现象，在短时间内形成均匀且厚的镀层。在化学镀方法中，金属粉末的平均粒径可以不小于1nm且不大于100μm，并且化学镀方法也可以应用于作为方法的大马士革法或双镶嵌法用于在半导体元件内形成精细的金属布线。上述结构可以提供一种化学镀方法，其可以通过利用诱导共析现象利用亚临界流体或超临界流体在短时间内通过无电解电镀实现均匀的膜的形成。 ®KIPO＆WIPO 2009
