Abstract

A laser direct writing technique for forming insulating layers of silicon dioxide from an organosilicate film on various substrate materials is shown. The process resolution is a function of the thermal properties of the substrate and is shown to be 1 μm. The technique allows for a local variation in the oxide thickness by changing process parameters. The quality of the laser written layers is compared to similar films formed by conventional organosilicate processing.
