Nb/Al-AlOx/Nb tunnel junctions designed for x-ray detection have been manufactured and characterized at temperatures down to 0.35 K. At a bias voltage of 0.5 mV, a leakage current of the order of 0.1 pA/mu m(2), and a dynamic resistance exceeding 10(6) times the normal state resistance, were achieved in junctions with dimensions up to 200 X 200 mu m(2) and critical current densities of order 200 A/cm(2). The combination of high critical current density, low leakage current, and large area represents an important step towards the development of superconducting tunnel junction detectors with improved spectroscopic performance.
