Electronic and photonic devices having ultra-micro structures fabricated with a focused ion beam

摘要

The present invention relates to devices each of which has an ultra-micro structure formed using a focused ion beam (FIB). In many cases, the structure has a shape of plate standing itself on a substrate. Although typical examples of the devices according to the present invention are a field effect transistor and a laser diode, the present invention is not limited to only such devices. The field effect transistors and the laser diodes according to the present invention have new functions or improved characteristics.
