Abstract:
A plasma deposition device for forming a thin film having a function of introducing material gas to an interior of the deposition device, a function of generating a plasma state from said material gas by providing electric energy thereto, a function of resolving said material gas into active species, and a function of depositing said active species on a deposition substrate and forming a thin film, wherein;said device is equipped with a plurality of electrodes that are grouped in a predetermined arrangement and positioned separately from said deposition substrate, wherein each of the plurality of electrodes has a discharge generating surface that faces parallel to the surface of said deposition substrate, and electric energy is supplied to said device by applying voltage between said electrodes to generate discharge, such that an arch shaped electric field discharge passage is formed between adjacent electrodes of the plasma deposition device, and such that based on the predetermined arrangement of the plurality of electrodes, (a) a potential difference is formed between some, but fewer than all of the plurality of electrodes, and (b) varying amounts of plasma are generated between at least some of the plurality of electrodes.
