  • Publication number: 20080166474
    Abstract: In a manufacturing method of a conductive composite particle, a conductive composite particle is manufactured that is formed of an active material particle having a region capable of electrochemically inserting and desorbing lithium and a carbon layer joined to the particle surface. In the carbon layer, fine metal particles are dispersed. This method has the following three steps. In the first step, a polymer material containing the metal element composing the fine metal particles is prepared. In the second step, the active material particle surface is coated with the polymer material containing the metal element. In the third step, a carbon layer having a porous structure including a fibrous structure is formed as the surface layer section from the polymer material by a treatment where the active material particle coated with the polymer containing the metal element is heated in an inert atmosphere to carbonize the polymer material.

  • Publication number: 20050233477
    Abstract: A substrate processing apparatus which is capable of enhancing productivity in manufacturing product substrates. In process chambers 106 and 107 of an etching apparatus 100, etching is carried out on a substrate as an object to be processed, and dummy processing is carried out on at least one non-product substrate before execution of the etching. A host computer 200 determines whether or not the dummy processing is to be executed. The host computer 200 determines whether or not the interior of each of the process chambers 106 and 107 is in a stable state, and omits the execution of the dummy processing when it is determined that it is in the stable state.
