摘要: A method of making optical gratings by the use of a Scanning Electron Microscope wherein (1) a substrate having a thin film of electron resist thereon is exposed in adjacent areas by an electron dosage and the amount of such dosage and the depth of the thin film are selected such that energy deposition in regions between adjacent exposed areas in said electron resist is below the threshold sensitivity of said resist for development, (2) the development time of the resist is made an inverse function of the electron dosage, and/or (3) the period of the grating is controlled by use of a standard scanning format.
