摘要:
An electrostatic chuck for attracting an insulative substrate to be processed, the electrostatic chuck comprising a dielectric layer having a first surface which attracts an insulative substrate, and a second surface on which are provided a plurality of electrodes, and an insulative support base plate fixing said dielectric layer. A distance between adjacent ones of the electrodes and the thickness of the dielectric layer are adjusted such that when a potential difference is established between the electrodes, a non-uniform electric field is formed in which the insulative substrate is partially polarized and attracted to the first surface by gradient force.
摘要:
A chuck equipment which can hold insulating substrates is provided. First and second electrodes are provided to be exposed on the base the surface of which is insulated. The insulating substrate is placed in contact with or in close proximity to the surfaces of the first and second electrodes. Since an electric field having a high rate of spatial change is established between the first and second electrodes, the substrate is held against the surface of the chuck equipment by the gradient force. Since the magnitude of the gradient force depends on that of the rate of change of the electric field, a voltage may be applied between the first and second electrodes to establish an electric field of 1.0×106V/m or greater.

摘要:
A multi-stepped substrate having a plurality of steps is produced by forming, on the principal surface of a substrate, a plurality of masks which are put on top of each other, which differ from each other in the materials used for forming them and which are likewise different, from each other, in the means for peeling off the same; and that the substrate is subjected, in order, to dry-etching operations through the plurality of masks each having a desired shape such that the substrate has a plurality of steps each of which reflects the shape of each corresponding mask.
