Abstract:
1. A static electricity deflecting device for a substrate processing apparatus which irradiates a substrate under processing with an electron beam and processes the substrate with the electron beam, comprising: a passing portion which causes the electron beam to pass; a plurality of groove portions radially formed from the passing portion; a space portion which is disposed at an outer position of each of the plurality of groove portions and whose width is larger than a width of each of the plurality of groove portions; a conductive film disposed in each of the plurality of space portions such that the conductive film is visible from the passing portion, the conductive film being substantially grounded; an insulative portion disposed in each of the plurality of space portions such that the insulative portion is not visible from the passing portion; and an electrically conductive film which electrically connects the conductive film, wherein each of the plurality of groove portions has a first connection portion connected to the passing portion and a second connection portion connected to the space portion, the second connection portion being wider than the first connection portion.
