Abstract:
1. A deposition method comprising: providing a heat flow control heat transfer part that is located between a placing stage on which a first electrode is placed and the first electrode, or that comprises a part of the placing stage; placing a processing object on the first electrode; generating plasma between the first electrode and a second electrode to generate active species that contribute to deposition of a film, wherein a density of the active species is lower at a peripheral area of the processing object than at a central area of the processing object; depositing a film on the processing object; and during the depositing, creating a differential between (i) a thermal resistance between the central area of the processing object and the placing stage and (ii) a thermal resistance between the peripheral area of the processing object and the placing stage, such that a heat flow is caused from the central area of the processing object toward the peripheral area of the processing object; wherein the differential is created by the heat flow control heat transfer part, which is opposed to at least one part of the peripheral area of the processing object.
