This paper presents the characteristics of metal thin-film pressure sensors. The micro pressure sensors consists of a chrom thin-film, patterned on a Wheatstone bridge configuration, sputter-deposited onto thermally oxidized Si wafer an aluminium interconnection layer. The fabricated micro pressure sensors shows a low temperature coefficient of resistance, high-sensitivity, low non-linearity and excellent temperature stability. The sensitivity is 1.16~1.21 mV/V.kgf/$\textrm{cm}^2$ in the temperature range of 25~l0$0^{\circ}C$ and the maximum non-linearity is 0.21 %FS.
