Abstract
The stable and low-power heating characteristics of a microheater are very important for the micro gas sensor. Membrane-type gas' sensors ha ve been fabricated by silicon IC technology. Steady-state thermal anal ysis by the finite-element method is performed to optimize the thermal properties of the gas sensor. From the analysis, the desirable size o f the microheater for low power consumption is determined. The heating properties of fabricated poly-Si and Pt microheaters have been tested . The sensing characteristics of the packaged microsensor are also exa mined.
