First Claim
Patent Images
1. A method for manufacturing a transparent, electrically conductive member, by forming an electrically conductive layer on a transparent substrate, comprising the steps of:
- heating the substrate to a first deposition temperature;
thermally decomposing and oxidizing a tin compound in the vicinity of the substrate under conditions such that a tin oxide layer is deposited on the substrate;
bringing a halogen containing doping material into the vicinity of the substrate during the deposition step, whereby said tin oxide layer is doped as it is deposited; and
without thereafter raising the temperature of the deposited doped layer above the deposition temperature, performing a heat treatment on the doped tin oxide layer at a temperature between 250°
C. to 400°
