Abstract
PURPOSE:To prevent the concentration of an electric field to the surrounding section of a material to be treated, and to execute uniform electric treatment to the whole surface of the material to be treated by forming an electrode in the same shape as the material to be treated and in a shape smaller than the size of the material to be treated. CONSTITUTION:When electrode plates 180, 190 are connected to the positive pole of a DC power supply 20, a wafer 100 is connected to a negative pole and mesa grooves 9, 10 are coated with glass impalpable powder through an electrophoresis method, the electrode plate 180, 190 are formed in the same shape as the wafer 100 and in the shape smaller than the wafer 100. Accordingly, the thickness of a glass protective film can be uniformalized because the current density of the central section and surrounding section of the wafer 100 is equalized.
