Popis: In this paper, we fabricated silicon piezoresistive pressure sensor with dry etching technology which used Deep-RIE and etching delay technology which used SOI(silicon-on-insulator) wafer. We improved pressure sensor offset and its temperature dependence by removing oxidation layer of SOI wafer which was used for dry etching delay layer. Sensitivity of the fabricated pressure sensor was about 0.56 mV/VkPa at 10 kPa full-scale, and nonlinearity of the fabricated pressure sensor was less than 2 %F.S. The zero off-set change rate was less than 0.6 %F.S.
