| Outline of Final Research Achievements |
For highly thermal sensitivity, downsizing of the sensor was required. pn junction, which is capable of downsizing by microfabrication techniques, was employed as a measurement principle due to its temperature dependence of electrical resistance. The fabrication process to enclose a pn junction based thermal sensor in a vacuum area in a microfluidic chip was established, and the characteristics of the fabricated device was evaluated. The thermal resolution of the device was 31.3 nJ. Further downsizing is possible by using electron beam lithography, and the thermal resolution could be improved more than 1000 times. In this research, the feasibility of the thermal device having pico-Joule thermal resolution was indicated.
