It is well known that the progress in basic technologies in computer electronics is very rapid. For example, a degree of integration of semiconductor chips has drastically increased during the past decade. A clock frequency of CPU for the recent personal computer is about fifty times higher that that of ten years ago. These high-tech devices require the development of new materials with new functions and new processes. In addition, it is expected that a new Intelligent Transport System (ITS) and global communication networks will be constructed at the beginning of twenty first century. These new high-tech infrastructures also strongly require the development of new materials with intelligent functions. This paper reviews the recent progress in new functional materials and new processes. First, several types of functional materials based on atomized powders are described. Next, a light emitting diode (LED) promising for optical communication devices is reported. Finally, a new type of precision casting method of titanium in combination with levitation melting has been introduced.
