Brain function improving agents, cognitive judgment ability improving agents, as well as foods and beverages that contain krill oil as an active ingredient are provided. The IC elements 10 are placed individually in cutouts 74, into each of which one IC element 10 can be inserted, the cutouts being formed in the outer circumference of a disk-like carrier 70. The high rate synthesis andor analysis of an array of materials uses deposition control techniques in conjunction with the electrode array to develop a meaningful array of materials and to analyze the materials for desired characteristics to develop one or more materials with desired characteristics. A depletion region is formed between the low doped well and the substrate when a reverse bias voltage is applied to the ESD device.
