2115919 9304359 PCTABS00020 Screen printing technology is employed in the batch fabrication of the contacts and polymeric membranes of solid-state ion-selective sensors. The process achieves high yield with very reproducible results. Moreover, membrane thickness can easily be predetermined, as it is directly related to the thickness of the screen or stencil. The process of the present invention is compatible with many integrated circuit manufacturing technologies, including CMOS fabrication. Advantageous polymeric membrane paste compositions include a polyurethane/hydroxylated poly(vinyl chloride) compound and a silicone-based compound in appropriate solvent systems to provide screen-printable pastes of the appropriate viscosity and thixotropy.
