he structure and behavior of defects, especial point defects are the key to understand the structural imperfection of structuresensitive advanced ceramics and related devices. A conception of chemistry and physics, especially for electronics on the point defect in the advanced ceramics is briefly reviewed in the present work. Several achieved examples of defect engineering and microscopic control technology for improving some ceramics/devices of electric, magnetic, optical, mechanical and/or biological behavior by defect improve/rebuild are discussed. The knowledge of how defects influence the ceramics/device performance is revealed and point defects provide very useful tools for understanding their basic characteristics and to open up their potentiality of the new advanced ceramics/devices in the near future.
