Electronic component used as an OFW/SAW component has a substrate plate covered with a tin dioxide layer, and an electrical conductor structure

摘要

Electronic component (1) has a substrate plate (10) and an electrical conductor structure (12, 13). The substrate plate is covered with a tin dioxide layer (16) as passivating layer in the region to be passivated over the conductor structure. An Independent claim is also included for a process for the production of a tin dioxide layer on a surface of a substrate plate over conductor structures comprising photolytic oxidation of a tin IV compound to form tin dioxide.
