PCT No. PCT/EP92/00990 Sec. 371 Date Jan. 7, 1993 Sec. 102(e) Date Jan. 7, 1993 PCT Filed May 6, 1992 PCT Pub. No. WO92/21020 PCT Pub. Date Nov. 26, 1992.The invention relates to a process for producing miniaturized chemical and biological sensor elements with ion-selective membranes. To simplify production in the micro range, an aperture (5,6) starting from the front (3) and tapering toward the back (4) is made in a thin silicon substrate (1) so that the front and back are interconnected. A liquid with which the ion-selective membrane is formed is poured into the containment (2) thus formed. Vertical ISFETs may also be made on the above principle.
