Dear members: We are looking for conductive epoxy suitable for so-gel application, i.e, it can be spinned cast on Si and will cure under normal conditions. We need to adhere piezoelectric material onto Si wafer using this method. Does anybody know such a product that can provide some decent conductivity and adhesion? Also, does anybody know where can I get thin Si wafers with Si3N4 (or SiO2) on BOTH sides? Thank you in advance. Qun LI Dept. of Biomedical Engineering Louisiana Tech University
