Abstract :
In this paper, we fabricated drag force type gas flow sensor with dry etching technology which used deep RIE (reactive ion etching) and etching stop technology which used SOI (silicon-on-insulator). we fabricated two kinds of sensor, which are cantilever type and paddle type. Both cantilever and paddle type flow sensors have similar sensitivity as 0.03 mV/VldrkPa.
