  • Physical Vapour Deposition Processes
    Publication number: 20110263073
    Abstract: A method of depositing a film of a first material, such as Cadmium Telluride on to a second material, such as Cadmium Sulphide by a physical vapour deposition process wherein said deposition is performed in an atmosphere having a relatively high ambient pressure, in one embodiment between 50 and 200 Torr.
    Type: Application

  • Method of forming 3-D structures using MOVCD with in-situ photoetching
    Patent number: 4933299
    Abstract: MOVPE growth and photoetching are integrated into a unified sequence which is carried out without removing a workpiece from a MOVPE reactor. Growth may be carried out before, after or before and after the etching.To prevent pattern broadening by diffussion of the active species the substrate is preferably protected by a fugitive coating which is removed by the illumination. Native oxide coatings are particularly suitable for InGaAsP substrates. These are conveniently applied for exposing to substrate to 20.degree./o O.sub.2 +80.degree./oN.sub.2 for about 3 minutes at 450.degree. C.
