Thin film layer deposition - using acoustic waves formed by local pulsed heating at substrate surface through laser beams

摘要

In the development of thin film layers, together with photo-acoustic assistance, acoustic waves are directed across the surface of the substrate to be coated during deposition. The waves are formed by local pulsed heating through laser beams directed at the substrate. USE/ADVANTAGE - The thin film layers are deposited for special applications with specific characteristics such as conductivity, magnetic, piezo-electric, ferro-electric, optical etc. The technique does not require interdigital converters to deposit thin film layers. The acoustic waves give thin film layer deposition on substrates which are not piezo-electric.
