In the development of semiconductor device which is facing the difficulties of miniaturization, introduction of material with self-assembling ability is one of the most important methods to overcome those difficulties. In this study, we propose a nanosystem utilizing biosupramolecules as biotemplate. Biosupramolecules have many fascinating features such as size uniformity and self-assembling ability, which cannot be realized in conventional inorganic materials. Various inorganic materials that are very important materials for fabricating semiconductor devices can be incorporated inside the molecules. This meritorious technique is called biomineralization. It can be performed at room temperature. We established the technique to place the above-mentioned material accurately from one (linearly) to three (sterically) dimensions on the semiconductor substrate. In this chapter, we introduce several examples of application to electron device, such as floating gate memory, resistive memory, thin film transistor, MEMS sensor, solar cell, and metamaterials. We successfully demonstrated the new function by utilizing these unique features. This technique will open the door to next generation semiconductor devices.
