Abstract
The application of hybrid microelectronic manufacturing techniques to the construction of ion-selective electrodes is considered. A solid state pH glass electrode has been manufactured using thick film techniques. The electrode structure studied consists of a conductive and a glass layer on a substrate. Major problems associated with the making of the pH–sensitive glass paste and the choice of conductive layer material are discussed. With the correct choice of materials and by using a suitable manufacturing process a linear electrode response can be achieved.
