Throughout the history of mankind, scientists and engineers have relied 
on the slow and serendipitous trial-and-error approach for compounds discovery. 
In the 1990s, the combinatorial approach was pioneered in the pharmaceutical 
industry in order to dramatically increasing the rate at which new chemicals 
are identified. The high-throughout concept is now widely being applied to a 
variety of fields. We have developed combinatorial thin film synthesis and 
characterization techniques in order to perform rapid survey of previously 
unexplored material space in search of new inorganic functional materials. 
Various thin film deposition schemes are implemented for fabricating massive 
arrays of compositionally varying thin film samples in the form of combinatorial 
libraries and composition spreads. A suite of high-throughput characterization 
tools including scanning SQUID microscopes and microwave microscopes are 
employed to track change in physical properties of the materials as a 
function of sweeping composition changes. Issues regarding handling the 
large amount of data and materials informatics from the viewpoint of 
combinatorial experimentation will be discussed.
