摘要:
A liquid displacement is performed by supplying a plating liquid onto a substrate 2 while rotating the substrate 2 at a first rotational speed in a state that a pre-treatment liquid remains on a surface of the substrate 2 (liquid displacement process (block S305)). Then, an initial film is formed on the substrate 2 by stopping the rotation of the substrate 2 or by rotating the substrate 2 at a second rotational speed while continuously supplying the plating liquid onto the substrate 2 (incubation process (block S306)). Thereafter, a plating film is grown by rotating the substrate 2 at a third rotational speed while continuously supplying the plating liquid onto the substrate 2 (plating film growing process (block S307)). Here, the first rotational speed is higher than the third rotational speed, and the third rotational speed is higher than the second rotational speed.

Methods for fabricating the high performing device permit cost effective, high production rates of the device and its component structures without any degradation in device performance resulting from component layering.
摘要:
A method of depositing at least one metal skin layer on a metal nanoparticle core is disclosed. The first step of the method is selecting a metal to deposit. Then, the metal nanoparticle core is dispersed in an electrolyte solvent to form a liquid mixture. Next, a hydrogen containing gas is bubbled through the liquid mixture to form a layer of adsorbed hydrogen atoms on the surface of the metal nanoparticle core. Finally, the selected metal is added to the liquid mixture to form a metal skin layer on the metal nanoparticle core.
