Paper Abstract

Miniaturized sensor for thermal analysis is fabricated using micromachining technique and its fundament al characteristics are obtained. This device fabricated in a Si substrate consists of monolithically integrated components of an air-bridge type microheater, a thin film thermocouple and a sample-holder. Boiling points of liquid samples, water and methanol, are observed in the heating curve and the heating-rate curve, and sudden decrease of the temperature at the dropping time of the liquid samples at room temperature due to the effect of evaporation heat is also observed. Loss of the sample due to the evaporation during heating was theoretically discussed.
