摘要:
A method of processing a substrate according to a PECVD process is described. Temperature profile of the substrate is adjusted to change deposition rate profile across the substrate. Plasma density profile is adjusted to change deposition rate profile across the substrate. Chamber surfaces exposed to the plasma are heated to improve plasma density uniformity and reduce formation of low quality deposits on chamber surfaces. In situ metrology may be used to monitor progress of a deposition process and trigger control actions involving substrate temperature profile, plasma density profile, pressure, temperature, and flow of reactants.

A temperature controlled showerhead for chemical vapor deposition (CVD) chambers enhances heat dissipation to enable accurate temperature control with an electric heater. Heat dissipates by conduction through a showerhead stem and fluid passageway and radiation from a back plate. A temperature control system includes one or more temperature controlled showerheads in a CVD chamber with fluid passageways serially connected to a heat exchanger.

This invention relates to an aerosol injection nozzle designed with a specific geometry to place materials vertically “upwards”, i.e., in opposite direction to the gravity and its method of use. With the nozzle is possible to deposited coatings, multilayer, composite materials, nanopins, nanorods, nanoclusters, nanoplates, nanowires, nanoparticles, “quantum dots” or semiconductors confined, of different materials, not limited to the examples above: TiO2 oxides, ZnO, ZrO2, SnO2, CuO, NiO, CrOx, AlOx, PbZrTiO3, LiNbO3; noble metal Ag, Au, Pt; polymer PANI, PEDOT. The process can be repeated in successive stages with the same device and with the same method to get one or several coatings or materials in successive stages.
