发明名称 Formation method of metallic electrode of semiconductor device and metallic electrode formation apparatus
摘要 A formation method of a metallic electrode of a semiconductor device is disclosed. The method includes: acquiring data about surface shape of a surface part of a semiconductor substrate; and causing a deformation device to deform the semiconductor substrate based on the data so that a distance between a cutting plane and the surface part falls within a required accuracy in cutting amount. In deforming the semiconductor substrate, multiple actuators are used as the deformation device. A pitch of the multiple actuators is set to a value that is greater than one-half of wavelength of spatial frequency of a thickness distribution of the semiconductor substrate and that is less than or equal to the wavelength.
