AB  - Sodium ion sensitive field-effect transistors (ISFETs) based on reactively 
      sputtered sodium aluminosilicate (NAS) glass membranes are investigated. Using an 
      inverted cylindrical magnetron, NAS films with defined and reproducible 
      composition are obtained. Radiation damage in the gate dielectric is largely 
      eliminated by annealing at 450 degrees C. The Na(+) sensitivity, the selectivity 
      with respect to H(+) and K(+) ions, the response time, the conditioning period, 
      the long-term drift, and the lifetime are evaluated. The ISFETs exhibit a 
      near-Nernstian Na(+) response down to 10(-4) mol/l in solutions of pH>/=7. The 
      NAS films are physically very robust and have excellent chemical durability, 
      e.g., a sensor with a 110 nm thick membrane lasts for about 8 months. The overall 
      sensor properties compare well with those of a commercial Na(+) selective glass 
      electrode.
