| Research Abstract |
Micromachining technology enables to integrate various kinds of micro-electro-mechahical systems used in wide fields. Nano-scale mechanics that are miniaturized from micro to nano scale make the performance higher, especially in mechanical, thermal, optical. properties. Objects of this research are the fabrication and the evaluation of high-density data storage device based on scanning probe microscopy with an ability to write and read bits with the size of 25 nm, which is fabricated by the micro/nanomachining technology. In conventional optical storage, heating by focused laser beam enable to write and read bits on a disk, however, the diffraction of light limits the recording density. To overcome this problem, the focused laser is replaced with many nano-scaled heater as a recording head in this research. In this research, we developed fundamental fabrication technique and demonstrate the performance and other related techniques were investigated. Ultra-thin silicon beams as a high sensitive sensing element are developed and these mechanical properties are characterized. Near-field micro components which can use an extremely localized light-field are developed as well.
